KX-TDA0480 Overview


KX-TDA0480 Overview

1.1 KX-TDA0480 Overview

The KX-TDA0480 is self-contained H.323 Version 2 compliant communications device (Gateway) that allow organisations to route both voice and fax communications over any TCP/IP network.The KX-TDA0480 installed in the IP PBX can be used to seamlessly bridge PSTN and analogue telephone with digital data networks, allowing organisations to more fully exploit their existing intranet and internet facilities. Most importantly, since communications take place over digital data networks, the high cost of long distance communications over conventional telephone networks is virtually eliminated.In the simplest sense, the KX-TDA0480 converts outgoing voice or fax signals into a digital format, compresses and packages the signal for transmission over digital TCP/IP networks. On the incoming side, the KX-TDA0480 reverses this process, receiving voice or fax data packets and translating them back into appropriate voice and fax signals.

Simplified IP Gateway network connection

In summary, the KX-TDA0480 provides organisations with a reliable solution for high quality integrated voice and fax communications using existing LAN/WAN environments without interrupting or compromising ongoing data communications.The KX-TDA0480 incorporates many features that help to assure a robust and easy-to-use product that delivers high quality voice communication and error free fax transmission.

Fax InterfaceThe KX-TDA0480 IP Gateway card is capable of real-time fax transmission using IP (T.38) transmission, thereby taking full advantage of the data network's flow and data control (TCP or UDP transmission).

KX-TDA0480 Overview

DTMF Detect and RegenerationThe KX-TDA0480 is capable of detecting and regenerating DTMF signals. Sending units are able to detect and convert DTMF tones for reliable transmission. On the receiving end, the unit regenerates DTMF tones, assuring accurate transmission when interfacing with Auto Attendant/Voice Mail or Interactive Voice Response systems.

Voice QualityThe KX-TDA0480 provides high-quality voice compression encoding which can be configured on a priority basis to automatically select between 64kbps PCM stream as either G.729A (8kbps), G.723.1 (6.3kbps) or G.723.1 (5.3kbps) compression and packet priority control.In addition, proprietary dynamic jitter buffer and Dynamic Echo Cancellation further assure uninterrupted and natural speech communications.

Network ConnectivityThe KX-TDA0480 supports a 10BaseT Ethernet interface for network connection. WAN connectivity is provided through any IP router.

H.323 ComplianceThe KX-TDA0480 is H.323 Version 2 compliant.

When implemented within an H.323 network, units are simultaneously managed as H.323 compliant gateways, using H.323 Gatekeeper device call control, address management, and bandwidth control capabilities.

IP and Telephone Numbering ManagementThe KX-TDA0480 employs a unified telephone numbering management system. It is easy to create a numbering plan that conforms to numbering plans of PBX.IP to telephone number translation can be handled in a number of ways.

KX-TDA0480 Overview

1. In H.323 compliant networks (e.g., Gatekeeper devices are employed) translations are handled by an H.323 Gatekeeper device.

2. Finally, internal DNS capabilities can also be combined to optimise network performance.

SNMP CapabilitiesThe KX-TDA0480 can be configured to use network management control through SNMP (Simple Network Management Protocol - MIBII).

Remote Control and ManagementInstallation and configuration of the KX-TDA0480 is performed using Maintenance Console Software (MCS).For first-time installation the Maintenance Console Software is used in conjunction with a common RS232C interface in order to establish a unit's new IP addressing. Once this is done and units are on-line in the network, the Maintenance Console Software can be used to configure and troubleshoot units remotely.

Alternatively, the KX-TDA0480 configuration files can be manually configured and uploaded to units, or the KX-TDA0480 on-line configuration commands can be entered directly to a unit. The advanced unit configuration techniques are applied using an RS-232C, LAN, or a Telnet/FTP link.

T.38 ComplianceReal time Internet Fax communication in accordance with ITU-T recommendation T.38 is offered.

Planning

The KX-TDA0480 provides versatile and reliable low cost voice and fax over IP networks. The equipment and software are designed to be easily integrated into existing data and telephony networks. Proper planning will make the installation process go more easily and will assure that the network can be easily maintained and upgraded. This section covers the following planning related topics; (1) General discussion of the KX-TDA0480 configurations and components. (2) Presentation and description of worksheets used to record information needed to install and configure a IP network.


Planning

2.1 Basic Configuration Overview

The KX-TDA0480 is an H.323 Version 2 compliant Internet Voice Gateway card. Units are designed to provide voice and fax transmission over an IP network, permitting the creation of voice/fax networks over any IP compatible intranet and Internet.IP-to-telephone number translation can be managed using H.323 Gatekeeper functions or the KX-TDA0480's internal DNS functions.

A basic configuration is shown in Figure "Basic network configuration".

A few conditions must be met for the KX-TDA0480 installation.

• The KX-TDA0480 must be connected to the LAN using an Ethernet interface and must be connected to the WAN (e.g., IP network) using a router.

• Only one IP network (Internet, Intranet, and VPN) can be used to interconnect communicating devices.

• The KX-TDA0480 requires that the network used support static IP addressing.

Basic network configuration

Static addressing means that the IP addresses allocated to various devices in the network are represented by fixed values. In some network applications, particularly large ones, addresses are sometimes dynamically allocated (DHCP/BOOTP). When this is the case, a block of IP addresses must be allocated for static assignment for the KX-TDA0480.

Sample network configuration

In the sample network, the New York Main Office and the Los Angeles and San Francisco branch offices are using the KX-TDA0480 to realise low-cost voice and fax communications through the IP network.

This sample is used throughout this manual to illustrate network and unit configurations. Also see the IP addressing and numbering plan network diagrams in Appendices A1 and A2.And this network is configured using the KX-TDA0480's internal DNS functions to manage network IP address-to-telephone number translations. See Appendix A3 for details regarding this function.

Although the sample network described above illustrates many of the KX-TDA0480's capabilities, it represents only one of many possible network configurations. The various features and methods for implementing KX-TDA0480 products are discussed in greater detail in the following sections of this guide.

Whatever the configuration envisioned, when planning a network installation, take care to avoid configurations that introduce unnecessary delays in transmission time. This is especially important in the case of Firewall protection systems or VPN (Virtual Private Network) devices. See Appendix A5 Optimising Performance: for a discussion of methods for optimising communications.

Planning

2.1.1 H.323 Version 2 Networks

The H.323 Version 2 standard is an important step toward the standardisation of equipment and software used in IP telephony. The KX-TDA0480 is compliant with the standards set forth under the H.323 specifications. The sample network used throughout this document is configured as H.323 and examples of the parameters needed for network configuration are provided. Below is a brief discussion of the H.323 standard and the role the KX-TDA0480 plays in the scheme of things.

H.323 Network OverviewH.323 is a device-independent, comprehensive set of multimedia communications standards set forth by the International Telecommunications Unit (ITU). Among others issues, H.323 sets forth standards for multimedia communications over IP-based Local Area Networks (LANs) and Wide Area Networks (WANs) and for end-point (terminal) devices which interact across the networks.When implemented within an H.323 network, the KX-TDA0480 compliance helps to insure that:

• The KX-TDA0480 is interoperable with other H.323 compliant devices, irrespective of manufacturer.

• Communications between various networks (LAN and WAN), and between end-point devices (terminals), is as seamless as possible.

• The impact of high network loads caused by bandwidth intensive applications such as video and telephony applications, are more easily handled through H.323 bandwidth management.

• The effects of variable LAN latency inherent in various networks are minimised.

• End-point terminals with differing capabilities (data, audio, and video) can interact.

The H.323 standard sets forth four major components that participate in an H.323 "conference".

H.323 Network Entities

• Terminals

• Gateways

• Gatekeepers

H.323 Gatekeeper Zone


Planning

• Multipoint Control Unit (MCU)

GatekeepersThe Gatekeeper is the vital link in an H.323 enabled network. It acts as the central point of management for all calls within its zone and it provides call control services to all registered endpoints.These devices perform several vital functions:

• Gatekeepers are the central points at which LAN identifiers for terminals and gateways (e.g., telephone numbers) are translated into IP and IPX addresses.

• Gatekeepers can perform bandwidth management tasks that help minimise the impact of high network loads produced by bandwidth intensive communications.

• Gatekeepers are also capable of providing additional services. For example, they can be used to balance call loads and to keep billing records for calls placed within their zone.*1

GatewaysIn an H.323 network, the KX-TDA0480 is classified as a Gateway device.Gateways can provide many different kinds of service but almost all provide translation services that enable end-point terminals of different types to communicate with one another seamlessly. TCP/IP network Interfaces are provided for analogue telephone and fax, a digital/analogue proprietary telephones, PBX, and PSTN networks.When the KX-TDA0480 is installed in an H.323 network, the unit is in continuous communication with the H.323 Gatekeeper and uses the call addressing and management services provided by the Gatekeeper.In addition, the KX-TDA0480 provides the interface between the worlds of voice and data communications, performing for example, voice compression/decompression and voice and fax data packetisation and de-packetisation.

TerminalsAt a minimum, H.323 terminals support voice communications, but may also support video and data. Three other required components are Q.931 for call signalling and call setup, Registration/Admissions/Status (RAS), which is used for Gatekeeper and Gateway communications, and support for RTP/RTCP sequencing of audio and video packet data. These requirements apply to all H.323 devices. Although the KX-TDA0480 is capable of communicating with other H.323 compliant devices, the current implementation is intended to communicate with PSTN terminal devices such as; analogue telephones, PBXs, Key Telephone Systems, and other telephone networking devices.

Multipoint Control Unit (MCU)MCUs manage the process by which calls involving three or more terminals are setup and managed. The capabilities may be implemented in stand-alone equipment or may be integrated into Gateway and/or terminal devices.

*1 Gatekeeper "additional services" vary based upon device manufacturer.


Planning

2.1.2 DNS

In networks not using an H.323 Gatekeeper, DNS facilities are used to perform telephone number-to-IP address translations. When DNS is used, the DNS facility provides each KX-TDA0480 in the network with the network IP address-to-telephone number information needed to communicate with other units in the network.The KX-TDA0480 has an internal DNS facility that can be used to perform this task.

CharacteristicsFor the KX-TDA0480 internal DNS, this information is recorded and uploaded to all units using the KX-TDA0480 DNS.DAT file.The MCS is used to generate and upload the DNS.DAT file containing definitions for up to 511 units. The following information is entered during DNS.DAT file creation:

• Unit Code

• Number of digits in the unit's extension number

• Unit's IP address

• Connection port no.

Whenever units are added to a network or their number plans changed, all DNS configuration files must be updated. DNS configuration files should only be uploaded to units AFTER all network units have been setup in the MCS.

2.1.3 G3 Fax

The KX-TDA0480 is capable of transmitting faxes using the data network to which the unit is connected and will automatically differentiate between fax and voice transmissions. Fax communication over a data network uses error-checking flow control protocols that assure accurate transmission.When this feature is used, each unit supports up to four fax terminal connections. During fax transmission, the ports in use are temporarily unavailable for voice communication. The fax unit is connected to PBX unit port using a 2-wire line.The following information should be considered when installing and using the KX-TDA0480's fax features.

Characteristics• G3 fax conforms to ITU-T Rec. T.30 standards

• Up to four fax lines per unit

• Communication configuration is 14400, 9600, 7600, 4800 or 2400 bps with no fall back

Operational limits• Manual transmission and voice reservation functions of the G3 fax terminal cannot be used.

• Up to four fax communications per unit can be conducted at a time.


Planning

• Under high network load and poor transmission conditions, a fax communication may be dropped.

• During a fax connection, the KX-TDA0480 sends a Ring Back Tone (RBT) until a fax connection is achieved.

2.1.4 DTMF Detection

The KX-TDA0480 provides DTMF detection and regeneration capabilities.

Characteristics• Sending units detect and convert DTMF tones for reliable TCP transmission.

• Receiving units regenerate DTMF tones.

• Assures accurate and reliable transmission when interfacing with Auto Attendant/Voice Mail or Interactive Voice Response systems.

• Selecting the DTMF signal method which the KX-TDA0480 sends from among Auto, Alphanumeric, and Signal.

Operational limits• When a unit is configured to use DTMF regeneration, the feature may introduce some

transmission delay.In most cases (Voice Mail, IVR, Auto Attendant), it will be the calling party which will need to send DTMF tones by dialling numbers. As a general rule it is best to avoid duplicating detection on two communicating KX-TDA0480. This can be accomplished by always selecting the DTMF detect Outgoing parameter when using DTMF regeneration.In the example shown in DTMF Detection, two units use DTMF regeneration and are configured so that the feature is enabled only once irrespective of which unit initiates communications.

Planning

In the case of the third unit, with no DTMF regeneration enabled, duplication is also avoided since units with DTMF regeneration detects the absence of the feature on the unit and transmits DTMF using the voice path.


Planning

2.2 Worksheets

Because the KX-TDA0480 is designed to accommodate a variety of network scenarios, a wide range of parameters can be configured. Although in simpler installations, the default settings will often be sufficient, some applications may require that specific parameters be adjusted to match existing network interfaces.Whether the installation is simple or more complex, configuration information needs to be on-hand once the installation of the KX-TDA0480 begins. This information should be determined during the network planning process.At a minimum, IP addressing, telephone network, and telephone numbering plans must be provided. Additionally, Network, PBX, and PSTN interface parameters may be needed. Finally, information about special features to be implemented will need to be prepared.The worksheets described in this section are designed to assist in the network planning process and should be filled-out before beginning physical and logical installation. To make the process easier, they employ a top-down strategy, follow a recommended order of operations, and conform to the Maintenance Console Software's interface.Determining the information to be recorded on these worksheets requires a specific knowledge of any existing network, existing PBX telephone systems, and a thorough knowledge of IP network addressing methods and telephone numbering systems.Data from the Sample Network Diagram illustrated in Appendix A1 of this document are included. Where applicable, field defaults and applied values are indicated in the text by an underscore. Sample network IP addressing and telephone numbering examples are illustrated in Appendices A1 and A2.Reproduction masters for the worksheets can be found in Appendix A8.

2.2.1 Network Worksheets

The Network worksheets are designed to allow the planning process to be conducted using a top-down approach.Network worksheets organise information about the KX-TDA0480 in a summary fashion, so that the relationship between the network IP addressing and numbering plan can be easily seen.Also, if DNS facilities are used instead of an H.323 Gatekeeper, this information must be supplied to the DNS entities so that all KX-TDA0480 can be made aware of one another.Reproduction masters for all worksheets in this section are included Appendix A8 of this document.

2.2.2 Network Units List Worksheet

Use the Network Units List Worksheet to record unit identifications and IP addressing information to be installed in the network.This worksheet is designed for use as a master list of key unit information and is useful in planning the deployment of units.The seven fields are to be completed for each KX-TDA0480 installed in the network. The information contained on this worksheet will be transferred to individual unit setup worksheets discussed later in this section.See sections 4.7.2 Create a New Gateway (KX-TDA0480 Unit) and 4.7.3 Create a New


Planning

Group NameUse the Group Name field to assign a group in which to create and store the KX-TDA0480 in the Maintenance Console Software. Subgroups can also be created. The procedure for creating Groups is discussed in Section 4.6 of this document.Each KX-TDA0480 must be assigned to a Group. The New Group command is used to enter this information in the Maintenance Console Software. Although the Maintenance Console Software requires that this be done before units (Gateways) can be defined, it is used for unit identification only and is not recorded in the unit's configuration file (OFDD.VHO).DNS information is stored in the unit's DNS.DAT file.The Group Name field allows for entry of an unrestricted alphanumeric string.For convenience, the Group Names in the sample worksheet are designated as the names of the cities in which the units will be installed.

• This worksheet contains all of the information needed to initialise a network's KX-TDA0480 using the Maintenance Console Software Unit Setup Wizard.

• If this setup information is uploaded to each unit and the units are rebooted, it is possible to perform all remaining configuration tasks remotely using the Maintenance Console Software.

Planning

Unit NameUse the Unit Name field to record a name to be associated with each network unit (i.e., Gateway) in the Maintenance Console Software. Although the Maintenance Console Software requires this information before a unit can be defined and configured, it is used for unit identification only and is not recorded in the unit's configuration file (OFDD.VHO). The Unit Name field allows for the entry of an unrestricted alphanumeric string. In the sample worksheet the unit names are combination of office name and numbers (e.g., NY01, NY02, etc).

Unit IP Address (VHUB_IP)Use this field to record each network unit's unique IP address. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.The default setting is 192.168.1.200.IP addressing information is typically supplied by a network administrator.

Subnet Mask (VHUB_SUBNET)Use this field to record each network unit's Subnet Mask IP address. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 1 to 255 excluding 0.0.0.0 and 255.255.255.255. The default setting is 255.255.255.0.Subnet IP addressing information is typically supplied by a network administrator.

Route IP Address 1 (GW_IP)*1

Use the Route IP Address 1 field to record the IP address of the primary gateway to be associated with each of the network units.For each unit, the unit's Gateway 1 (i.e., primary Gateway) is the one that will be accessed by the unit during normal operation.The KX-TDA0480's gateway is typically a router or similar device. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value. IP addressing information is usually supplied by a network administrator.

• The IP and Gateway addresses must belong to the same Subnet. The unit will not operate properly and the alarm lamp will be lit when these values are incompatible. Although the MCS rejects conflicting addresses, care must be used if the VHUB_SUBNET parameter is configured manually, using the KX-TDA0480 on-line commands.

*1 The Gateway is the unit's link to Wide Area Network. The GW-IP refers to the IP address of the device (e.g., a router or similar device) to which the KX-TDA0480 forwards data packets for delivery to the IP network and from which the KX-TDA0480 receives data packets. In the case of an installation behind a firewall, this address is used to route the KX-TDA0480 data through the protection facilities. See Appendix A5 and the KX-TDA0480 Programming Guide for details regarding installation behind a Firewall.


Planning

Route IP Address 2 (GW_IP)*1

Use the Route IP Address 2 field to record the IP address of the secondary (e.g., backup) gateway to be associated with each of the network units.For each unit, the unit's Gateway 2 is the one that will be accessed by the unit if Gateway 1 (i.e., the primary Gateway) fails. The KX-TDA0480's gateway is typically a router or similar device. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value.IP addressing information is usually supplied by a network administrator.

Signal port no.Specification of TCP port number for call control (incoming calls)Setting range is from 0 to 60000. The default setting is 1720.

2.2.3 Connection Information Worksheet

If the IP Gateway network’s internal DNS capabilities are to be used in the network, use the DNS Connection Information Worksheet to record summary information needed to configure these facilities. The IP address and Destination Office Code information on this worksheet is also used to configure Gatekeeper Inter-equipment Routing (TRS.DAT) information. A complete discussion of IP Gateway network DNS configuration is provided in Appendix A3 of this document. See section 4.9.1 Configure Gateway Units (KX-TDA0480) for Maintenance Console Software procedures for configuring this information in the KX-TDA0480.

In the case of the KX-TDA0480 internal DNS functions, DNS information is recorded and uploaded to network units using the Maintenance Console Software. This is done only after all unit configuration files (OFDD.VHO) have been uploaded.The information is stored in the DNS.DAT files of all network units and is used to inform each unit of the existence, IP address, and telephone number of other units in the network.During network installation, this information is uploaded to every KX-TDA0480 in the network and must be held consistent in the network. If network units are later added, removed, or modified, the DNS.DAT information must be updated in all network units.Up to 511 IP address to telephone number translations can be included in the KX-TDA0480's internal DNS.DAT file.See Appendix A3 for details regarding Network DNS configuration.In the DNS.DAT file, PBX Office Code can be associated with multiple IP addresses corresponding to up to 30 KX-TDA0480.

Unit Name and IP AddressUse the Unit Name and IP Address field to record the unit name and IP address for each connection to be defined.This information can be transferred from the Network Units List Worksheet.

Connection port no.Specification of TCP port number for call control (incoming calls)Default: 1720

Terminal CodeUse the Terminal Code field to record the Terminal Codes for the immediate KX-TDA0480, PBX or Hunt Group being connected to.It is important to note that some of the KX-TDA0480 unit Terminal Codes in the sample network include a single digit from the destination number. For example, the PSTN destinations all have the digit 9, which is the PBX-PSTN Access Code. These extra digits speed connection time to the dialled extension by routing the call directly to

the desired destination. The DNS facility therefore, has less look-up work to do.The number of extension digits included in the Terminal Code can be greater than that used in the sample, but the Remaining Digits field must be adjusted accordingly. See Remaining Digits, below.

• The Terminal Code is that of the PBX to which the unit is connected.In the sample network, NY01 is PBX Office Code 21. The digits 5, 7, and 9 have been added to facilitate routing to extensions 500-599, 700-799, and PSTN Access Code 9. The result is that the Terminal Codes for this unit are 215, 217, and 219.NY02 has the same destinations as those for NY01, but also includes the PBX Office Code 27 because this unit is associated with a Trunk Group routed to PBX 27. No additional digits are included so the Terminal Code is simply 27.

Remaining DigitsRecord the number of digits in addition to the Terminal Code digits to be associated with the destination unit. This is usually the number of digits used for the extension number.

• For the sample: NY01, most of the destinations have remaining digits set to 2. The one exception is the PSTN destination, in which case the remaining digits is 10, allowing PSTN numbers up to 10 digits in length to be accessed (e.g., 805- 555-1212). Setting remaining digits to 10 does not mean that the user must dial all 10 digits when calling a number.

CommentsUse the Comments field to record free text information regarding the unit. This information is for reference purposes and is recorded in MCS files only.

2.2.4 Common Configuration Worksheet

In most circumstances, some configuration information is common to all units within a network, or at least within a network group. The Maintenance Console Software provides a Common Configuration facility that makes it easy to configure parameters that are shared by all of the units in a group.

Use the Common Configuration worksheet to record values for parameters that are common to many units within a network. The common configuration items include DNS, SNMP, Gatekeeper, and Notify E-mail.

• These parameters can also be entered individually for each unit, using the Unit Configuration folders.


Planning

DNS SetupUse the DNS Setup section to set the receiving figures of the KX-TDA0480 starting address translation.When an H.323 Gatekeeper is not used in the IP Gateway network, the KX-TDA0480 internal DNS are used to perform telephone number-to-IP address translation. See Appendix A3 of this document.

SNMP SetupIf an SNMP compatible network management system is present, use the SNMP Setup section of the worksheet to record information about available Trap IP addresses and the facility's Community name.SNMP Simple Network Management Protocol is a TCP/IP Protocol suite Application Layer utility that provides a mechanism to manage and control network equipment from a central console system. The KX-TDA0480 report any error codes or fault codes to the central console (Network Management System NMS) by sending out Traps.

Trap IP 1 (SNMP_TRPDST)Record the IP address for the first Trap Transmission facility. The IP address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. There is no default value for this field. In the sample, there is no Trap 1 IP address.

There is no default value for this field. In the sample, there is no Trap 2 IP address.

Trap IP 3 (SNMP_TRPDST)Record the IP address for a third Transmission facility. The IP address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value for this field.In the sample, there is no Trap 3 IP address.

Community Name (TRP_COMMU)Record the SNMP Community Name. The name may consist of a string of from 1 to 8 characters (e.g., public, proxy, private, etc.)

GatekeeperUse the Gatekeeper section of the worksheet to record the IP address for a primary and optional secondary Gatekeeper.

WARNINGTo configure other Gatekeeper devices refer to the manufacturer's documentation.

A Gatekeeper provides the telephone number-to-IP Address translation plus additional services, depending on the feature set of the Gatekeeper used. When an H.323 IP Gateway network is implemented, a Gatekeeper device must be configured as part of the network. Provisions are also made for a secondary (backup) device.*1

If no Gatekeeper is used, the KX-TDA0480 internal DNS features must be used. In this case, no entries are required for Gatekeeper devices.

Gatekeeper 1 IP (GK_IP)Use the Gatekeeper 1 IP field to record the IP address for a primary Gatekeeper device. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn,

*1 H.323 Protocol recommends one H.323 Gatekeeper within a Zone and a secondary (redundant) Gatekeeper for the same zone. See the Gatekeeper unit's documentation for details.

• When an H.323 Gatekeeper address is entered during unit configuration, the Gatekeeper takes precedence over all other network management facilities. The KX-TDA0480 internal DNS settings will be ignored.


Planning

where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. There is no default value for this field.In the sample, no secondary Gatekeeper device is defined.

Gatekeeper 2 IP (GK_IP)Use the Gatekeeper 2 IP field to record the IP address for a secondary Gatekeeper device. This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. There is no default value for this field. In the sample, no secondary Gatekeeper device is defined.

Notify E-mailThe KX-TDA0480 is capable of generating unit event e-mail notifications through the SMTP server interface. Events for which notifications are produced include Power-on, Command Reboot, Unit Reset, and Fan Fault. If the parameters for Notify E-mail are not configured, the feature is disabled.

Primary SMTP ServerRecord the IP address of the primary SMTP server. The IP address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value for this field.

Secondary SMTP ServerIf a secondary (backup) SMTP server is configured, record the IP address of the secondary server. The IP address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value for this field.

E-mail Address 1Record the e-mail address to which unit event notifications are to be sent.There is no default value for this field.

E-mail Address 2If desired, record a second e-mail address to which unit event notifications are to be sent.There is no default value for this field.

2.2.5 Unit Setup Worksheet

The Unit Setup Worksheet is used to record all of the information needed to install and configure the KX-TDA0480. Some of this information can be transferred from the network worksheets discussed earlier in this section.

The worksheet has a front and backside. There is also an extension to the worksheet.

The worksheet is divided into sections that correspond to the Unit Setup Wizard and Edit Data configuration tabs in the Maintenance Console Software.Worksheet fields with default values are subtitled with these values in parentheses.

Worksheet examples in this section are for the named units in the Sample Network in Section 2.1 Basic Configuration Overview. Also see the network diagrams in Appendices A1 Voice Over IP Addressing and A2 Numbering Systems.

Once this worksheet is completed, the information is used to logically configure a unit. The logical parameters are configured using the Maintenance Console Software. Once this information is entered into the software, the configuration file is uploaded to the unit and is recorded in unit’s internal OFDD.VHO file.

The Maintenance Console Software procedures for entering and uploading unit configuration data are provided in Section 4 Logical Installation of this document.

This worksheet should be completed for each KX-TDA0480 to be installed in the network. Care must be taken to assure that the information provided is correct and complete. Inaccurate or incorrect information may result in problems that are difficult to diagnose once the network is operational.

Reproduction masters for these worksheets are included in Appendix A8 Worksheet Masters of this document.

Planning

Unit Identification InformationUse the unit identification information line to record information used to identify a Group to which a unit belongs, and to identify the individual unit.

Group NameUse the Group Name field to assign a group in which to create and store the KX-TDA0480 in the Maintenance Console Software.

Each KX-TDA0480 must be assigned to a Group. The New Group command is used to enter this information in the Maintenance Console Software. This must be done before units (Gateways) can be created.

The Unit Name field allows for entry of an unrestricted alphanumeric string.

In the sample worksheet, the Group Name is New York.

Unit NameUse the Unit Name to enter a name to be associated with a unit (Gateway) in the Maintenance Console Software. The Maintenance Console Software requires this information before a unit can be defined and configured using the Maintenance Console Software.

The Unit Name field allows entry of an unrestricted alphanumeric string.

In the sample worksheet, the Unit Name is NY01.

GeneralUse the General section of the worksheet to record unit IP addressing and password access information.

See Appendix A1 Voice Over IP Addressing.

Unit IP (VHUB_IP)Use this field to record a unit's unique IP address.

This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. The default setting is 192.168.1.200.

IP addressing information is typically supplied by a network administrator.

In the sample worksheet the Unit IP is recorded as the default address, 133.149.1.91.


Planning

Subnet IP (VHUB_SUBNET)Use this field to record the Subnet Mask IP address.

This address must conform to Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn = a value of 1 to 255 excluding 0.0.0.0 and 255.255.255.255. The default setting is 255.255.255.0.

IP addressing information is typically supplied by a network administrator.

There is no default value for this field.

In the sample worksheet, the Subnet mask IP address is the same as the default, 255.255.255.0.

Gateway 1 IP (GW_IP)Use the Gateway address field to record the address of the primary gateway to be associated with the unit. This is the gateway that will be accessed by the unit during normal operation.

The KX-TDA0480's Gateway is typically a router or similar device. This address must conform to Internet Protocol addressing requirements. E.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. This address usually applies to a router or similar device, to which the unit is connected.

IP addressing information is usually supplied by a network administrator.


In the sample worksheet, the Gateway 1 IP address is recorded as 133.149.1.1.

Gateway 2 IP (GW_IP)Use the Gateway address field to record the address of the secondary gateway, if present.

The KX-TDA0480's second Gateway address is optional. It is used to designate a secondary (backup) device to be accessed in the event that the primary gateway becomes unavailable. This address must conform to Internet Protocol addressing requirements. E.g. nnn.nnn.nnn.nnn, where nnn = a value of 0 to 255 excluding 0.0.0.0 and 255.255.255.255. This address usually applies to a router or similar device, to which the unit is connected.

IP addressing information is usually supplied by a network administrator.


In the sample worksheet, the Gateway 2 IP address is recorded as None (e.g. there is no secondary gateway).


Planning

User PW (PASS_U)Use the User PW field to record a User access level password.

Passwords may be from 1 to 10 alphanumeric characters long and are case sensitive. Upper and lower case characters can be freely mixed.

The default User password is user.

In the sample, the User password is entered as user (e.g., the default password).

Maintenance PW (PASS_M)Use the Maintenance PW field to record a Maintenance access level password.

Passwords may be from 1 to 10 alphanumeric characters long and are case sensitive. Upper and lower case characters can be freely mixed.

The default User password is mainte.

In the sample, the User password is entered as mainte (e.g., the default password).

ToneThis parameter is irrelevant to the setting of the KX-TDA0480.

NumberingThis parameter is irrelevant to the setting of the KX-TDA0480.

Trunk DataUse the Trunk Data section of the worksheet to record information needed to configure each of the active ports on the KX-TDA0480.

Port No. (ITRK)The Port # field indicates the port to be configured (e.g., ports 1 to 2). To the right of each port are fields for the port's setup parameters. Provide information for each of the unit's active ports.

• If a port on the KX-TDA0480 is not used, this should be indicated and, in the Maintenance Console Software, the Clear button should be used to remove all default settings. Failure to logically disable an unused port can result in calls being lost because they are erroneously routed to an inactive port.


Planning

Trunk Group (ITRK)Use the Trunk Group Field to define from 1 to 2 Trunk Groups to be associated with the KX-TDA0480: Trunk Group 1 and Trunk Group 2.

A Trunk Group consists of a collection of trunks on the KX-TDA0480. At least one group must be defined and up to four Trunk Groups (ports 1 to 2) can be defined for the KX-TDA0480.

Trunk Groups

In the sample, the Trunk Group parameter for all ports is recorded as the default, 1 (e.g., All ports are members of the same Trunk Group).

Delete Digits (TGNINFO)Use the Delete Digits field to record the number of digits to be deleted from the received number.

In the sample, the Delete Digits parameter for all ports is configured to the default value of 0.

Length of Call Reference (ITRK)This parameter must always be set to "1".

Interface Type (ITRK)This parameter must always be set to "Basic Interface".

Planning

PAD In and PAD Out ( PAD_VALUE)For each port, use the PAD In and PAD Out fields to record the amount of PAD to be introduced into the communication between the KX-TDA0480 and the PBX main unit.

PAD is a voice line gain/loss function expressed in decibels (dB) which is introduced into communications between the KX-TDA0480 and the PBX main unit. This feature is used to emulate the loss normally generated in PSTN network transmission.

The following values are provided in the MCS list box.

+14dB, +12dB, +10dB, +8dB, +6dB, +4dB, +2dB, 0dB, -2dB, -4dB, -6dB, -8dB, -10dB,-12dB, -14dB, -40dB

The recommended value for the KX-TDA0480 is 0dB since the PBX introduces its own padding towards its extensions.

In the sample, the PAD In and PAD Out parameters for all ports are configured to the defaults for the KX-TDA0480, In = 0dB and Out = 0dB.

In a few cases, these settings may need to be adjusted. See Appendix A4 Pad Control and AGC for details. Adjustments of the nature must be performed on a case-by-case basis.

DTMF Detect (DTMF)The KX-TDA0480 capable of using of DTMF.

When DTMF is enabled, the unit passes digits after a call has been established, the KX-TDA0480 on the originating end detects the DTMF tones, captures them, and packetises them for TCP transmission to the destination KX-TDA0480 where regeneration occurs.

When DTMF is disabled, DTMF is transmitted over the voice path.

The available settings include:

• Care must be taken to calculate the end-to-end gain/loss when reconfiguring the PAD In and PAD Out parameters since these settings can have a cumulative effect when both are configured.

No: DTMF will not be detected.

Outgoing (Default): DTMF will be detected for outgoing calls.

Incoming: DTMF will be detected for incoming calls.

Both: DTMF will be detected for incoming and outgoing calls.


Planning

As a general rule it is best to avoid duplicating detection on two communicating KX-TDA0480. This can be accomplished by always selecting the DTMF detect Outgoing parameter when using DTMF regeneration.

AGC (Automatic Gain Control)For each port, record the AGC function levels to be used if this feature is to be enabled.

The AGC (Automatic Gain Control) feature operates at the PAD In side of the unit. If this feature is to be enabled, the allowed values are recorded in dBm in the range of +3 to -60 dBm. It is recommended that the PAD In value be set to 0 dBm when AGC is enabled.

The default configuration is for AGC disabled.

Protocol Type (IPROT)Set a type of the ISDN Layer 3 signal protocol, or a call control signal. Only QSIG is supported.

Hunt PatternUse the Hunt Pattern section of the Worksheet to record information how called numbers are processed through the PBX main unit.

The Hunt Pattern defines which Trunk Group will be accessed when a call is processed and how the call will be routed through the PBX main unit.

Destination numbers always consist of one or more PBX Codes. Each Trunk Group defined in the Trunk Data folder can be associated with a PBX Code. When there are two or more Trunk Groups defined for a single KX-TDA0480, grouped ports can be associated with more than one PBX by configuring them with the appropriate PBX Codes. Conversely, the Trunk Groups of several units can be configured with the same PBX Code.

When a Trunk Group is associated with a PBX Code (Destination number), it is then associated with Hunt Pattern Number (1 or 2). The Hunt Pattern number is used to configure the Trunk Priority Feature discussed in the next topic.

From 1 to 2 Hunt Patterns can be defined (e.g., A pattern for each Trunk Group that has been defined for the unit). The relationship between ports, Trunk Groups, Hunt Patterns and PBX Codes is:

Per Unit Minimum Maximum

Ports 1 2

Trunk Groups 1 2

Hunt Patterns 1 2

Destination No. 1 128


Planning

The default configuration is for one Trunk Group made up of all two ports. This configuration is defaulted to Hunt Pattern 1 and would be associated with a single PBX Code (Destination number). In the Trunk Priority folder settings this single group is defaulted to Priority one.

If the default configuration is used, then all that is necessary is to define the connection characteristics for the single Trunk Group (e.g., Trunk Group 1). Since no additional Trunk Groups are available, no additional Hunt Pattern information is required and the Trunk Priority section of this worksheet can be ignored.

If additional Trunk Groups are defined (e.g., Trunk Group2 etc.) then Hunt Patterns and Trunk Priorities must be configured.

See the next Topic in this section, "Trunk Priority".

Destination Number (HNTPTN)Use the Destination Number field to record the PBX Code to be accessed when calling through the KX-TDA0480 (8 digits maximum). Every Hunt Pattern must be associated with a PBX Code.

Hunt Pattern No. (HNTPTN)Use the Hunt Pattern No. field to record the number of the pattern to be associated with the Destination Number. Each Destination number will have a Hunt Pattern number associated with it (i.e., 1 or 2.).

Trunk PriorityUse the Trunk Priority section of the Worksheet to define the order (priority) in which alternate Trunk Groups will be searched in the event that a connection is not established within the first Trunk Group. This feature can be used to distribute traffic on PBX port.

Priority 1 is the first Trunk Group searched. If a connection cannot be established in the Priority 1 group, additional Trunk Groups are searched in priority order.

The Destination numbers searched using this feature are determined by the Hunt Pattern Number assigned in the Hunt Pattern section of the worksheet. (See previous Topic.)

• It is not possible to direct calls to a specific port within a Trunk Group.

• Trunk Groups must be defined using Trunk Data before Hunt Patterns can be configured.


Planning

Up to 2 Hunt Patterns can be defined for each unit.

Hunt pattern # (TGNPRIORITY)Records are provided for up to four Patterns. Record the Trunk Group numbers for each pattern to be created.

Priority # Trunk Group No. (TGNPRIORITY)Enter the Trunk Group Number defined in the Trunk Data section of the worksheet in the appropriate priority column (e.g., For defined Trunk Groups, number will be 1 or 2).

Voice ModeUse the Voice Mode section of the worksheet to record configuration parameters affecting the manner in which the KX-TDA0480 handles voice data packets.

Each port (1 to 2) can be configured individually.

Port (RTP_HEAD)The Voice Mode section is organised so that configuration parameters can be entered for each port on the KX-TDA0480. Provide information for each of the unit’s active ports.

Protocol (RTP_HEAD)Use the Protocol field to record the voice protocol to be used by the port. Two options are possible.

In the sample, the Protocol for all ports is recorded as the default value, H.323.

Codec Information (AUDIO_CAP)The principle difference between Codecs is their compression capabilities and their performance in delay and latency environments.

The KX-TDA0480 allows the selection of one or two Codecs.When two Codecs are selected, one must be configured as High Priority and the other as Low Priority. A single Codec cannot

• These parameters are entirely independent from the network configuration (H.323 compliant or DNS), and can be used freely in either network configuration.

H.323 (Default): Use this protocol to have the unit use H.323 voice control protocol (RTP/RTCP).

Oki: Use this protocol to have the unit use Oki's proprietary voice control protocol.


Planning

be assigned for both priorities.

When the KX-TDA0480 attempts to establish a connection with another VoIP gateway, the gateway goes through a capabilities exchange and negotiates the CODEC to be used.

The KX-TDA0480 will try to use the High Priority Codec first. If the remote gateway does not support the High Priority Codec, the Low Priority Codec is offered.

Use the Codec Information field to record the voice transmission Codec(s) to be used by all ports on the unit. Also specify the Codec priority when two Codecs are used. G723.1 is the default value for H.323 networks. G.729A can also be selected. The Efficiency to Quality settings will vary based on the Codec selected.

In the sample, G.729A is the only Codec configured for use.

Efficiency to Quality (VOICECOND)The ratio of Payload to Bandwidth for each Codec can be adjusted. The default values are shown in the following table.

The bytes and bandwidth values are inversely related in a predetermined ratio. In the Maintenance Console Software, the values are adjusted using a slide-bar control that maintains the correct ratio.

In the sample, Efficiency is recorded as the default value, 80 bytes/12.0 Kbps.

NetworkUse the Network section of the worksheet to record parameters used in checking network connectivity between the KX-TDA0480 and the immediate Ethernet switch or router to which the unit is connected.

To perform checks, the KX-TDA0480 transmits ICMP error checking packets on a defined error checking timing cycle. If no reply is detected, the link between the unit and Ethernet switch is broken.

This feature's information is typically used in cases where the KX-TDA0480 are working in groups associated with a PBX. In this case, failed links can be bypassed as calls are rerouted through active links.

Codec Default Parameters

Codec Payload Bandwidth

G.729A 80 bytes 12K

G.723.1 (5.3) 160 bytes 7.5K

G.723.1 (6.3) 192 bytes 8.46K


Planning

Regular Timing (UPLINK)Regular Timing period in seconds. Every "Regular Timing" seconds, an error checking packet will be transmitted during normal operation. If "Regular Timing"=0, no checking is performed. Otherwise, "Regular Timing" should be in the range of 1 to 999.

The default setting for this value is 0 seconds.

Error Detect Timing (UPLINK)Error Detect period in seconds. Every "Error Detect Timing" seconds, an error checking packet will be transmitted during link failure. "Error Detect Timing" should be in the range of 1 to 999.

The default setting for this value is 3 seconds.

Generally, "Error Detect Timing" should be smaller than "Regular Timing" because more frequent checking is required when the link is down.

Disconnect on Errors (UPLINK)During Regular Timing checking, if "Disconnect on Errors" times bad packets are detected then "link failure" is declared. Regular Timing checking is halted, and Error Detect checking is started."Disconnect on Errors" should be in the range of 1 to 100.

The default setting for this value is 10 times.

Reconnect on Errors (UPLINK)During Error Detect checking, if "Reconnect on Errors" times good packets are detected then "normal link" is declared. Error Detect checking is halted, and Regular Timing is started."Reconnect on Errors" should be in the range of 1 to 100.

The default setting for this value is 1 times.

Call ControlUse the Call Control section of the worksheet to record parameters associated with Gateway-to-Gateway and Gateway-to-Gatekeeper communications and for control for the KX-TDA0480.

The start and signalling port parameters designate the signalling ports on which communication will be initialised and on which transmission will take place, respectively.

As a rule, the default values should be used.


Planning

Signalling Port (CALL_PORT)Use the Signalling Port field to record the port on which transmission will be initiated.

In the sample, the unit is configured to the default value, 1720. This value affects one port only.

H.245 Start Port (H.245_PORT)Use the H.245 Start Port field to record the port on which H.245 signalling will be initiated.

In the sample, the unit is configured to the default value, 1721.

This value affects the four ports. The designated port and the next three ports in sequence (e.g., 1721, 1722, 1723, and 1724).

RTP Start Port (RTP_PORT)Use the RTP Start Port field to record the port on which RTP signalling will be initiated.

In the sample, the unit is configured to the default value, 5004.

This value affects eight ports. The designated port and the next seven ports in sequence. Even ports are RTP (e.g., 5004, 5006, 5008, and 5010). Odd ports are RTCP (e.g., 5005, 5007, 5009, and 5011).

Connect Time (NOCTIME)Use the Connect Time field to record the time allowed for a connection to be established.

This parameter defines the time frame during which the KX-TDA0480 will try to establish the call. If a call is not established within this time (e.g., the called KX-TDA0480 is not responding) a fast Busy Tone is returned. When implementing KX-TDA0480 in a dialup WAN scenario -WAN connection setup time must be included as a timing consideration.

The range of acceptable values includes from 1 to 99 seconds.

In the sample, the unit is configured to the default value, 30 seconds.

UDP Port No. for Supplementary Service (ISDN_ANF_PORT)A port used to transfer QSIG signals in an IP network when they are received, using the QSIG connectionless supplementary service. The default value of this port is 5003. When using this type of port, it will be necessary to unify it within the network.

DNS Setup, SNMP Setup, Gatekeeper, and Notify E-MailRefer to Section 2.2.4 Common Configuration Worksheet.


Planning

Recovery DelayThe KX-TDA0480 Recovery Delay feature controls a secondary Jitter buffer that is activated dynamically when enabled. This feature allows the unit to recover from network delays by temporarily storing voice data in a Jitter (recovery) buffer. In the event of a network delay, the stored voice data is transmitted, assuring an uninterrupted conversation.

Several configuration parameters can be configured for this feature.

Maximum Receive Buffer Size (RX_BUFFER)Record the maximum allowable size of the Jitter buffer. In most cases, the default size (1920 ms) will provide the best results.

Start Recovery (RX_BUFFER)Record, in units of ms, the delay time threshold value for the start of recovery delay processing*1. In most cases, the default value (200 ms) will provide the best results.

End Recovery (RX_BUFFER)Record, in units of ms, the delay time threshold value for stopping the recovery delay processing which started at the time specified as Start Recovery data. In most cases, the default value (30 ms) will provide the best results.

Other

Cause of Fan Fault (FAN_FLT)This parameter is irrelevant to the setting of the KX-TDA0480.

A-law/m-law Flag (LAW_FLAG)Assign as appropriate to the network Codec set at the PBX.

The default setting for this field is m-law.

*1 Recovery Delay Processing is defined as the operation of discarding soundless voice packets from the jitter buffer.


Physical Installation

Section 3


Before beginning the KX-TDA0480 unit installation process, it is recommended that all planning worksheets be completed. The following sequenced steps make for a quick and efficient installation. With experience, installers may adopt variations on these procedures that suit their particular needs: (1) Connect Cables (2) Power-up Unit and Verify Physical Installation

Logical Installation

Section 4


Once the KX-TDA0480 has been physically installed, it must be logically configured for operation. The logical installation process described in this section involves the following operations; (1) Initialise the unit with new IP addressing information, (2) Configure unit specific parameters, (3) Upload configuration files and reboot the units. IP addressing and configuration parameters were discussed in detail in Section 2.2.2 of this document and the worksheets created at that time are used to perform the logical installation tasks described in this section.



4.1 Logical Installation Methods

There are several methods by which the logical configuration process can be performed.In all cases, each newly installed KX-TDA0480 must first be initialised with its new IP addressing through a direct RS-232C link to the unit. Once a unit has been initialised , it is possible to perform additional configuration tasks using one of the following methods.

• Use the KX-TDA0480 Maintenance Console Software to configure and upload configuration files. This can be done locally or remotely.

• Configure OFDD.VHO and DNS.DAT files off-line and use an FTP link to upload the configuration files to a unit.

• Configure a unit directly over a serial connection, line-by-line, using the terminal command line interface and on-line commands.

In this section, all configuration tasks will be performed using the Maintenance Console Software. Alternative methods for creating and uploading configuration files are described in Appendix A7 of this document.

The following procedures are discussed in this section.

• Install Maintenance Console Software

• Start Maintenance Console Software and Login

• Initialise Unit with Maintenance Console Software Setup Wizard

• Create/Edit Common Configuration

• Configure Unit Parameters

• Transfer Files and Reboot Units



4.2 Maintenance Console Software Overview

The KX-TDA0480 Maintenance Console Software (MCS) provides an easy-to-use interface for the installation and management of the KX-TDA0480. The MCS is a Microsoft® Windows® 98, Windows NT®, Windows 2000 or Windows XP compatible software product and will run on systems supporting that operating system. In addition, the computer terminal must have a floppy drive for installation and a serial port. Finally, to permit communication with the unit over the LAN, an Ethernet Network card using an RJ45 connector is also required.The Maintenance Console Software user's interface conforms to Windows 98, Windows NT, Windows 2000 or Windows XP conventions allowing users to use a mouse to pull down menus, point and click items, and select operational buttons to execute various operations. For additional information regarding the user interface, see the Windows 98, Windows NT, Windows 2000 or Windows XP user's documentation.In this section, procedures for using the Maintenance Console Software to install and configure the KX-TDA0480 is described.

4.6 Create a New Group

When first setting up a IP Gateway network, unit Groups must first be created. Groups are used to help organise the network configuration and will usually consist of units that are related to one another. For example, they will be in the same location.Groups can be created all at once or one at a time as the network setup process proceeds.Use the information recorded in the Network and Unit Configuration worksheets described in Section 2.2 of this document.

To create new Group:1. Mouse-click on the Main icon in the directory window Groups pane and select New and

Group from the Unit menu.

Note

• Click the Toolbar Create Group icon.



• Click the right mouse button in the Groups windowpane and use the Pop-up New Group menu item.

The MCS displays the Create new group dialogue box.

2. Select the Group Name field and type a new group name. Also type comments into the Comment field if desired.

3. Click on the OK button to accept the information displayed in the fields or Cancel to abort the changes.

The MCS updates the directory window Groups pane with the new group.

Repeat this procedure to create additional groups.



In the sample network, four groups have been created.



4.7 Create New Units

Once a new Group has been created, new units can be added to the group; Gateways*1 and Gatekeepers*2 and Other Unit*3. The Maintenance Console Software Unit Information Setup Wizard is used to create both types of units in exactly the same manner.A new unit is shipped with the factory default IP addressing information (i.e., 192.168.1.200). Although this information can be used to establish a LAN type connection, it is usually easier to first reconfigure the unit's IP addressing information to match that of the existing LAN, using a direct RS-232C serial cable connection.The Maintenance Console Software's Unit Information Setup Wizard method for doing this is discussed in the following procedures.If desired, once a unit has been created using this direct method, the unit setup information can be edited remotely, using a network connection.

*1 A Gateway is the KX-TDA0480 IP Gateway card.*2 A Gatekeeper is an H.323 device that is used to manage H.323 Voice-Over-IP networks. Only H.323 networks use a Gatekeeper.

the IP Gateway networks may also be configured using internal DNS server management capabilities.*3 An Other Unit refers to Other Device excluding Gateway and Gatekeeper.



4.7.1 RS232C Port Configuration

In section 3.3 the RS233C cable was connected with the terminal to be used for initialising the KX-TDA0480. The Maintenance Console Software is configured by default to use the port Com 1 for serial data transfer. If a serial communications port other than Com 1 is being used on the computer terminal used for unit initialisation, the MCS Options item must be selected from the Tools menu to reconfigure the Com port.

To reconfigure the serial communications port:

1. Select Options from the MCS Tools menu.

The MCS displays the Options folders

2. In the first folder (General), use the Select RS-232C port pull-down list-box to choose the desired port.



3. Click on the OK button to accept the new port setting. Click the Cancel button to abort the change.



4.7.2 Create a New Gateway (KX-TDA0480 Unit)

Unit Setup Wizard 5 of 6Use the Setup Wizard screen 5 to either accept the default User password or change the User password.The default User password is user typed in lower case characters. Be careful to make a record of any new password that is entered at this time*1.

1. If the default password is to be used, click on the Use Default check box and proceed to step 6.

2. If the User password is to be changed, select the Password field and type the new password. To enhance security, an * (asterisk) symbol will be echoed in place of each character typed.


3. Select the Confirm password field and retype the new password. To enhance security, an * (asterisk) symbol will again be echoed in place of each character typed.


*1 If the new password is lost, contact the Customer Support.



• If the password is changed and the Password and Confirm Password values are not identical, the MCS will issue an error message and redisplay screen 5 so that the password fields can be corrected. The passwords must match in order to proceed.



Unit Setup Wizard 6 of 6Use the Setup Wizard screen 6 to select the method for applying the unit setup information.

Two methods are available: Update Configuration File and Upload to Unit and Reboot.

Update Configuration FileUse the Update Configuration File to record the unit setup information to an MCS file for later upload to the unit. This method is not recommended for first time installation, since the unit IP addressing information entered in the Wizard must be written directly to the unit if the unit is to be accessed using a remote (e.g., LAN) connection.During subsequent remote (e.g., LAN) sessions, the Unit Information Setup Wizard can be accessed using the Edit Data and Change Unit Information item on the MCS Unit menu.

Upload to Unit and RebootUse the Upload to Unit and Reboot method for new units. In addition to recording the unit setup information to an MCS file, this method uploads the information directly to the unit, issues the unit "write to memory" command and reboots the unit.The settings configured using the Unit Information Setup Wizard take effect following the unit reboot, allowing the unit to be accessed over a LAN connection.



1. Click the Option radio button for method to be used; Update Configuration File or Upload to Unit and Reboot. Both methods will save the file to the MCS. If the Update Configuration File method is used, proceed to step 4.

2. If the Upload to Unit and Reboot method is selected, click the Reboot access method radio button for the method to be used to upload the data to the unit.

3. Click the RS232C radio button to select the upload method.

4. Click on the Finish button to complete the Wizard. Click on the Cancel button to exit the Wizard and lose all changes.

Once the Finish button is clicked the MCS will perform the specified operations.If the Update Configuration File method was used, the unit's updated OFDD.VHO file is saved, and the Main Directory windows will be redisplayed with the new unit displayed in the Units window pane. If the Upload to Unit and Reboot method is used, the MCS updates the Unit setup information in the unit and displays a confirmation message indicating the operation was successful. An error message will be displayed if a connection could not established.

In addition to the upload, the unit's updated OFDD.VHO file will be saved, and the Main Directory windows will be shown with the new unit displayed in the Units window pane.

• During the first time configuration (unit initialisation) the RS-232C cable must be connected to the unit and the COM port being used on the computer terminal must be properly selected to perform the following operation.

• During subsequent sessions, the unit setup (e.g., IP addresses) can be edited remotely using a LAN connection. This is done by selecting the Edit Data/Change Unit Information item on the MCS Unit menu. When this method is used, the computer and unit must be within the same subnet or communication will be lost after the new configuration becomes effective.

• As discussed in the previous note, the LAN upload method should only be selected for units that have been previously initialised and are already on-line in the network.

• The unit reboot process can take over a minute to complete. Observe the LED indications on the front panel of the unit to verify that the reboot process is complete before attempting to perform additional operations with the unit.



4.7.3 Create a New Gatekeeper

Gatekeepers are only created for H.323 managed networks. In the case of the KX-TDA0480, networks can also be managed through internal DNS facilities.When used, up to two Gatekeeper devices can be created for each H.323 Zone. The first device created is used as the primary device. Optionally, a secondary (e.g., backup) device can be created.

WARNINGThe Maintenance Console Software can only be used to configure an the Gatekeeper device. To configure other Gatekeeper devices refer to the manufacturer's documentation.

To create a Gatekeeper device, select the Group in which the device is to be located and then select the New Gatekeeper item from the Unit menu.

Note

• Click the Toolbar Create Gatekeeper icon.

• Click the right mouse button in the Groups window pane and use the pop-up New Gatekeeper menu item.

The MCS then displays the Setup Wizard for a Gatekeeper.



The process for setting-up a Gatekeeper unit is identical to that for a Gateway unit, except that the Type field is for a Gatekeeper only.Refer to the Setup Wizard procedures for a Gateway to set up the Gatekeeper.



4.7.4 Create an Other Unit

Other Unit refers to Other Device excluding Gateway and Gatekeeper.To create an Other Unit device, select the Group in which the device is to be located and then select the New Other Unit item from the Unit menu.

Note

• Click the Toolbar Create Other Unit icon.

• Click the right mouse button in the Groups window pane and use the pop-up New Other Unit menu item.

The information about Other Unit can be added easily to DNS.DAT by selecting Other Unit item from the devices list on priority connection information display.The MCS then displays the Setup Wizard for an Other Unit.



4.8 Create/Edit Common Configuration

The Maintenance Console Software provides a Common Configuration facility that makes it easier and quicker to configure parameters that are shared by all of the units in a group. The common configuration items include; DNS, SNMP, Gatekeeper, and Notify E-mail. These parameters can also be configured for individual units using the Unit Configuration folders described later in this section. This may be better when adding only a few units to an existing network.

To use the Common Configuration feature:1. Select a Group in the Groups Pane or from within a group, select the units to be configured

using the methods described earlier in this document.

2. Select the Edit Common Configuration item from the Unit/Edit Data menu or from the pop-up menu displayed by right-clicking on the selected units.

The MCS then displays the folders for the Common Configuration items.



3. All parameters configured in this manner will be applied to all units in the selected group or to the units selected in the Units Pane. The new parameters will appear in the Configuration folders for each unit.

• If a Gatekeeper unit is a member of the selected group, only the SNMP parameters will be applied to that unit.



4.9 Configure Units

Once a Gateway or Gatekeeper unit has been created using the Unit Information Setup Wizard, the Maintenance Console Software has created a configuration file (OFDD.VHO) for the unit. This file must now be configured with data that will allow the unit to operate properly in the network environment in which it is installed.The Maintenance Console Software permits all configuration file data to be entered and edited while off-line. Once the configuration data for one or more units has been entered into the MCS, each unit's configuration file can be saved to a hard disk and /or uploaded to unit's using the network interface.*1

In the procedures discussed in this section, the completed configuration files will be uploaded to the units using a LAN connection.See Section 3.4 for additional information about the LAN connection. To begin the configuration process, highlight the unit to be configured by clicking on the unit's icon and then select Edit data and Edit configuration item from the Unit menu.

Note

• Click the Toolbar Edit Configuration icon.

*1 Additional methods for uploading and downloading configuration files are discussed in Appendix A7 of this document.



• Place the mouse cursor over the unit to be configured, click the right mouse button, and use the pop-up menu's Edit configuration item.

The MCS then displays an Edit Configuration dialogue box asking if the unit OFDD.VHO file to be edited is the one that is currently recorded on disk by the MCS or if the OFDD.VHO file currently stored in the unit should be downloaded for editing.

• In the case of a newly created unit, the Saved configuration file option (default) should be selected.

• If a unit has been previously configured and its configuration file is not recorded on the MCS terminal currently in use, it may be desirable to download the OFDD.VHO file from the unit. In order to do this, the terminal must have an active LAN link with the unit. In this case, select the Download configuration file from Unit radio button.

Once a method has been selected, click on the OK button to proceed.Assuming that the Saved File option is selected, the MCS then displays a file selection dialogue box.



• If this is a newly created unit, only one file will be displayed in the Options list of this dialogue box. The file date will be the date on which the Unit Information Setup Wizard was run.

• If this unit has been configured previously, there may be two or more versions of the OFDD.VHO file displayed.

The file named with the .VHO extension will always be the most recent version of the configuration file stored on the MCS terminal. Older backup or rollback versions of the configuration file will always be listed with the extension. OLD and will be listed in data sorted order with the most recent shown toward to the top of the list.



Click on the desired file version in the Options list by clicking on it, and then click on the OK button to proceed.The MCS then displays the tabbed configuration folders for the Type of unit being configured.

In most cases, the order in which folders are selected for data entry is not important. In the few cases where order is important, the MCS will issue a warning message.To view a configuration folder, click on a folder's tab.

• Click the Cancel button in any folder to abort all of the edits made during the current configuration session.

Folder tabs



4.9.1 Configure Gateway Units (KX-TDA0480)

The Maintenance Console Software display uses a set of tabbed folders to organise the unit configuration process. Each of these folders contains fields in which configuration data are entered.The data to be entered should have already been identified and recorded on a Unit Setup Worksheet for the unit being configured. Field definitions and parameter descriptions are provided in Section 2.2 of this document.Much of the data recorded during the unit configuration process is critical to the proper operation of the equipment and care must be taken to avoid errors.

Each of the unit configuration tabs is discussed as follows.



General FolderUse the General folder to display and reconfigure unit Setup Information. This is the first folder displayed when beginning unit configuration.The folder displays information that was entered using the Unit Information Setup Wizard. Usually, no changes will need to be entered for this tab.

Use the Unit section to view and edit unit IP addressing information.

UnitDisplays the unit's name. This field cannot be edited from this folder.To change a unit's name, exit the Edit Data configuration screen and return to the directory window. Click the mouse cursor once on the Unit Name in the MCS Units windowpane. When the cursor changes to a text edit cursor, make the desired changes and then click the mouse over another section of the MCS window. The change made will be reflected in the Unit Information Setup Wizard and the General configuration folder.

Use the Password section to view and edit unit IP addressing information.



PasswordThe Maintenance and User passwords can be changed by clicking one of the Change Password buttons. The change procedure is the same for both password types.When a Change Password button is clicked, the MCS displays a change password dialogue box.


To change a password:1. Type the current password into the Current Password field.

2. Type the new password into the New Password field.

3. Type the new password a second time in the Confirm new password field.

4. Click on the OK button. Click the Cancel button to abort the operation.

The MCS will then close the Change Password dialogue box and return to the General folder.If the current password is incorrect, or if the new password confirmation does not match the new password, the MCS displays an error message.

Use the IP Addresses section to view and edit unit IP addressing information.

IP AddressType an IP address for the KX-TDA0480.If the unit was setup on the terminal currently in use, this value should not need to be changed.

Subnet MaskType a Subnet Mask IP address.If the unit was setup on the terminal currently in use, this value should not need to be changed.



Route Address 1Type an IP address for the primary Gateway (e.g., router).If the unit was setup on the terminal currently in use, this value should not need to be changed.

Route Address 2Type an IP address for the secondary/backup Gateway (e.g., router).If the unit was setup on the terminal currently in use, this value should not need to be changed.



Tone FolderUse the Tone folder to configure the unit tone set.Although the KX-TDA0480 allows for the creation and installation of custom tone sets, the following procedure is for configuring the unit with a predefined tone set.

Use the Tone field to select a predefined Tone set.In the Information section, the Tone library list shows the values for the currently selected Zone setting.

Tone selectUse the pull-down list to view available and choose a predefined Tone set.



Numbering FolderUse the Numbering folder to configure the unit numbering plan. This information includes the unit's (KX-TDA0480) Office Code.

Use the Office Code section to view and edit the unit's Office Code.

Office CodeType the unit's 1 to 16 digit Office Code. This value is required

Trunk Data FolderUse the Trunk Data folder to configure each of the Trunks on the KX-TDA0480.

The KX-TDA0480 has 2 ports. 2 voice communication channels are included for each port.

On the KX-TDA0480, a Trunk Group can be made up from 1 to 2. Typically, all ports used to form a Trunk Group will share the same configuration. As discussed latter, the Hunt Pattern folder can be used to specify a priority order in which these groups are accessed.

The Port parameters list displays the configuration parameters for each unit port.

If the list columns exceed the width of the list window, use the horizontal scroll bar to move the display to the right or left.

Also, the column widths can be adjusted by placing the mouse cursor over the right or left edge of the column field title. When the cursor changes to a cross, drag the column border to the desired width.

Scroll bar



To configure a port, select the port in the Port parameters list and configure each of the fields provided in the area beneath the list.

Trunk GroupUse the pull-down list to select the Trunk Group number with which the port will be associated.

In the sample above, all of the ports are configured as members of Trunk Group 1.

Delete DigitsType the number of digits to be deleted from the dialled number when calling this Trunk.

The maximum number of Delete Digits is 32.

This parameter should normally be set to "0".

Length of Call ReferenceSet to "1" all the time.

Interface TypeSet to "Basic Interface" all the time.

PAD InUse the pull-down list to select the PAD value (in dB) to be applied to voice signals coming into the unit.

It is usually best to use the default value for this field until it is determined by observation, that adjustments are required.

PAD OutUse the pull-down list to select the PAD value (in dB) to be applied to voice signals going out from the unit.

It is usually best to use the default value for this field until it is determined by observation, that adjustments are required.

DTMF detectUse the pull-down list to select the DTMF detection method to be used by the unit; No (ne), Incoming, Outgoing, or Both.

It is recommended that this be set to Outgoing.



AGCTo enable the unit's Automatic Gain Control, check the AGC check box and configure the AGC sensitivity using the scroll box to change the AGC dB value.

It is recommended that the PAD In value be set to 0 dBm when using this feature.

Protocol TypeSet a type of the ISDN Layer 3 signal protocol, or a call control signal. Only QSIG is supported.

DTMF transfer signal patternSet DTMF signalling method: Auto, Alphanumeric, Signal.

Complete the fields listed above for each active port on the unit.

• If a port on the unit is inactive, select the port in the Port parameters list and click on the Clear button to logically disable the port.

• If this is not done, calls can be lost because they are erroneously routed to an inactive port.



Hunt Pattern FolderUse the Hunt Pattern folder to record information about how called numbers are to be routed through the KX-TDA0480 to the PBX. Up to 128 destination numbers can be entered for a unit.

From 1 to 2 Hunt Patterns are defined. If more than one Hunt Pattern is defined, then the Trunk Priority features are used to configure the priority order in which alternate Trunk Groups are searched in the event that a connection cannot be established within first group.

To configure a Hunt Pattern, complete the fields located beneath the Patterns list and click the Update button.

Once the Update button is clicked, the new Pattern list will be updated with the new Pattern information.

Destination NumberType the Destination Number for the Hunt Pattern. Up to 128 codes can be configured.



Under normal circumstances, assign the same value as the value assigned for the PBX code at the PBX to this parameter (8 digits maximum per code).

Hunt Pattern No.Use the pull-down list to select the Hunt Pattern No. (1 or 2) to be associated with the Destination number field.



Trunk Priority FolderUse the Trunk Priority section of the Worksheet to define the order (priority) in which alternate trunk routes will be selected in the event that the first Trunk Group accessed is busy.

Priority 1 will be the first group searched. If the destination number is not found on the associated Trunk Group, then the remaining group is searched in priority order.

Up to 2 Hunt Patterns can be defined for each unit.

The Hunt Pattern list provides records for each Hunt Pattern that was defined in the Hunt Patterns folder. To configure a Hunt Pattern, select the desired pattern in the Hunt Pattern list and complete the fields located beneath the Hunt Pattern list.

The Hunt Pattern list is updated as new values are configured in the fields.

PriorityUse the pull-down list to select a Priority setting (1 or 2).



Trunk group numberUse the pull-down list to select a Trunk Group (1 or 2) to be associated with the Priority settings.

Only Trunk Groups that were defined in the Trunk Data folder are listed.



Voice Mode FolderUse the Voice Mode folder to configure parameters affecting the manner in which the KX-TDA0480 handles voice data packets.Each port (1, 2) can be configured individually.

The Configuration list shows the Voice Mode for each active port on the unit.Below the Configuration list are read-only fields for Packet parameters; Packet size and bandwidth.To configure a port's Voice Mode, select the port to be configured on the Configuration list and then modify the protocol field below the list using the Select protocol field.The Packet parameters are modified using the Efficiency slide bar on the right side of the dialogue box.The Configuration list and read-only Packet parameter fields are updated as the configuration is edited.It is also possible to select between two voice transmission Codecs.



Select ProtocolUse the pull-down list to choose a protocol for the selected port (H.323).This setting affects only the method in which voice data is handled by the unit and has no effect upon the selection of a network H.323 Gatekeeper or DNS facilities.

Packet send intervalUse the Efficiency slide bar to adjust the packet size to bandwidth ratio for the selected port.

To operate the Packet send interval slide bar, click on the control handle and hold the mouse button. Drag the control handle to the left or right to adjust the ratio. The values in the read-only Packet parameter fields are updated as the slide bar is manipulated.

CODEC InformationUse the Up-arrow and Down-arrow to configure the Codecs on the Configuration list.Select the Codec(s) to be applied for voice transmission by highlighting the item on the Configuration list and clicking the >> button to transfer the item to the CODEC list.Once selected, the selected CODEC(s) appear in the Packet parameters Selected field.



FAX related FolderData for specifying the selection priority sequence for the protocol to use when performing T.38FAX communication. When performing communication between two KX-TDA0480, the specified priority protocol (priority 1 capability type) can be locked if the specifications are the same. Even when connecting to other company products, the protocol can be used in the same manner if the specifications are the same.

FAX capabilityThe configuration can be selected from TCP and UDP (Redundant). Default setting is TCP.Left window: Protocol used. The priority level of the protocol is specified.Right window: Protocol which can be used. The protocol not immediately used is specified.Up/Down: The priority level of the protocol is changed.

Note

Do not move the protocol from the left window to the right window using the button.



FAX redundantSpecifies the number of times each packet information is resent to the connecting device when performing T.38 FAX communication using UDP. Different from TCP, there is no procedure for response check, etc., for UDP. Thus, the number of times to send information can be increased to assure that packet information is sent correctly. However, there will be a decline in the transmission efficiency when increasing the number of times the information is sent.

Bit orderData for specifying the send sequence of bit arrays when sending T.38 packet data.When sending as advised, specify the normal direction.When reversing the send sequence of bit arrays, specify the reverse direction.Selection will be made according to the conditions of the other party's device.The default setting is the reverse direction.

IFP packet max sizeMaximum size of IFP (Internet Fax Packet) that can be sent at one time.Since data can be sent in smaller units by decreasing the size, connection problems can be resolved on networks with long delays. However, decreasing the size will increase the packet overhead and result in increased of the network load. The default value is 290 bytes.



Network FolderUse the Network folder to configure the network timing parameters used to monitor the link between a Gateway and router, hub, or switching device to which the unit is connected. When link failure is detected, the error condition is reported.

Use the Information Section to view and edit the network timing parameters.

Regular time periodType the timing cycle over which the error checking packets will be transmitted during normal operation.The seconds value can also be scrolled up and down with the scrolling arrows located to the right of the field.

Error detect time periodType the timing cycle over which the error checking packets will be transmitted after an error has been detected. This value is usually set to a higher frequency than Regular Timing. If a normal return is detected during this period, the Regular Timing is resumed.



The seconds value can also be scrolled up and down with the scrolling arrows located to the right of the field.

Disconnect after errorsType the number of times that an error can be detected before the link is failed.The Times value can also be scrolled up and down with the scrolling arrows located to the right of the field.

Reconnect after errorsType the number of times that a recovered link is to be detected before the link will be reestablished as normal.The value can also be scrolled up and down with the scrolling arrows located to the right of the field.



Call Control FolderUse the Call Control folder to configure parameters associated with gateway to gateway communications and control.The start and signalling port parameters designate the signalling ports on which communication will be initialised and on which transmission will take place, respectively.

Use the Information section fields to modify the H.245 call start and signalling parameters, RTP start parameters, T.38 call start, and connection timing.

Call signalling port numberType the number of the port on which transmission will occur.The default port number is 1720. From 4 to 65524 can be specified except FTP(20,21), telnet(23) ports.

• The default values conform to the H.323 protocol and should always be used unless there is a known network conflict. If a conflict is detected, refer to the H.323 protocol specifications before making adjustments.



The port number can also be scrolled up and down with the scrolling arrows located to the right of the field.

H.245 start port numberType the number of the port on which the H.245 signalling will be initiated.The default port number is 1721. From 4 to 65521 can be specified except FTP(20,21), telnet(23) ports.The port number can also be scrolled up and down with the scrolling arrows located to the right of the field.

RTP start port numberType the number of the port on which RTP/RTCP signalling will be initiated.The default port number is 5004. From 4 to 65516 can be specified except SNMP(161), RAS(1718,1719).The port number can also be scrolled up and down with the scrolling arrows located to the right of the field.

T.38 start port numberType the number of the port on which T.38 signalling will be initiated.The default port number is 5012. From 4 to 65521 can be specified except FTP(20,21), telnet(23) ports.The port number can also be scrolled up and down with the scrolling arrows located to the right of the field.

UDP Port No. Supplementary serviceA port used to transfer QSIG signals in an IP network when they are received, using the QSIG connectionless supplementary service.The default port number is 5003. From 4 to 65524 can be specified except FTP (20, 21), telnet (23) ports.When using this type of port, it will be necessary to unify it within the network.The port number can also be scrolled up and down with the scrolling arrows located to the right of the field.

Connect time to establishType the time (seconds) that will be allowed for call signalling to be established.The range of acceptable values include from 1 to 99 seconds. The default value is 30 seconds.The Time value can also be scrolled up and down with the scrolling arrows located to the right of the field.

Restore defaultsClick on the Restore defaults button to return the values for all fields to their default condition.



DNS FolderDNS folder is used to configure the number of digits to receive to start number translation.

When an H.323 Gatekeeper is not used in the IP Gateway network, the KX-TDA0480's internal DNS server are used to perform IP address-to-telephone number translation.Modifications to DNS are described in A3 DNS Configuration:

• This information is recorded on the Common Configuration worksheet described in Section 2.2.4 Common Configuration Worksheet of this document, and can also be entered for selected unit groups using the Edit Data/Edit Common Configuration items on the Unit menu. See Section 4.8 for the procedure using the Common Configuration facility in the Maintenance Console Software.

Domain Name Not usable

IP address for DNS 1 Not usable



Search DNS afterSpecify the number of digits to receive to start number translation. This is a data to shorten the number translation time. When the KX-TDA0480 receives the specified number of digits, it will start number translation. Set this data value to 1 when it is configured in priority connection information that IP address will be determined by 1 digit. The default value is 1 digit.The digits value can also be scrolled up and down with the scrolling arrows located to the right of the field.

When the OK button is selected, the MCS saves the configuration information on disk in the unit's OFDD.VHO file and returns to the MCS directory window.

The updated OFDD.VHO file is now ready for upload to the unit using the Maintenance Console Software's file transfer features discussed in section 4.10 Transfer Setup and Configuration Files to Units.

Click the Cancel button in any folder to abort all of the edits made during the current configuration session.

The Maintenance Console Software then displays a confirmation dialogue box.

Select Yes to abandon all changes and return to the directory window.

Note

• Often, when many units need to be created and configured, several of the units will have similar configurations. When this is the case, a quick way to create and configure these additional units is to use the copy and paste commands to create copies of existing units.Once created, copied units can be quickly renamed and edited with new IP addressing and numbering information.

• Select the unit to be copied in the Units window pane and click the Copy button on the Toolbar.

• Click the mouse in a vacant area of the Units window pane to deselect the copied unit. Then click the Paste button on the Tools bar.

• The MCS names the copy "Copy of Unit ...".



• To rename the unit, click on its name in the Units pane and edit the name.

• Once the new unit has been renamed, use the Edit Data item on the Unit menu and select Change Unit Information to modify the setup parameters.

• Finally, use the Edit Data item on the Unit menu and select Edit configuration to modify the unit's configuration.

• The Cut, Copy, and Paste features are also displayed on the Unit's pane pop-up menus.

• Use these features to delete units, make copies of units, and move units from one group to another.



4.9.2 Configure a Gatekeeper Unit

Using the Maintenance Console Software to configure network Gatekeepers is very similar to the methods used to configure a Gateway but the number of configuration parameters is considerably fewer.

The Maintenance Console Software display uses a set of tabbed folders to organise the configuration process. Each of these folders contains fields in which configuration data are entered.

The data to be entered should have already been identified and recorded on a Unit Setup Worksheet for the unit being configured.

Much of the data recorded during the unit configuration process is critical to the proper operation of the equipment and care must be taken to avoid errors.As discussed earlier, when a unit is selected and the Edit Data command is used, the Maintenance Console Software asks if a saved file is to be edited or if the file in the unit should be downloaded.

If the saved file is to be edited, the Maintenance Console Software displays a dialogue box in which the file to be edited can be selected. See section 4.7 Create New Units to review this process.

Once the file to be edited has been selected, the Maintenance Console Software displays the configuration folders for the Gatekeeper unit.Each of these folders is discussed below.

• Only the Gatekeepers can be configured using the MCS. See the manufacturer's documentation for other Gatekeepers.

• When an H.323 Gatekeeper address is configured within the IP Gateway network, it takes precedence over all other network management facilities. The KX-TDA0480 internal DNS settings will be ignored.



General Folder (Gatekeeper)Use the General folder to display and reconfigure unit Setup Information. This is the first folder displayed when beginning unit configuration.The folder displays information that was entered using the Unit Information Setup Wizard. Usually, no changes will need to be entered for this tab.

Use the Unit section to view and edit unit IP addressing information.

Use the Password section to view and edit unit IP addressing information.

Unit Displays the unit's name. This field cannot be edited from this folder.To change a unit's name, exit the Edit Data configuration screen and return to the directory window. Click the mouse cursor once on the Unit Name in the MCS Units windowpane. When the cursor changes to a text edit cursor, make the desired changes and then click the mouse over another section of the MCS window. The change made will be reflected in the Unit Information Setup Wizard and the General configuration folder.

Password The Maintenance and User passwords can be changed by clicking one of the Change Password buttons. The change procedure is the same for both password types.When a Change Password button is clicked, the MCS displays a change password dialogue box.




To change a password:1. Type the current password into the Current Password field.

2. Type the new password into the New Password field.

3. Type the new password a second time in the Confirm new password field.

4. Click on the OK button. Click the Cancel button to abort the operation.

The MCS will then close the Change Password dialogue box and return to the General folder.If the current password is incorrect, or if the new password confirmation does not match the new password, the MCS displays an error message.

Use the IP Addresses section to view and edit unit IP addressing information.

IP Address Type an IP address for the KX-TDA0480.If the unit was setup on the terminal currently in use, this value should not need to be changed.

Subnet Mask Type a Subnet Mask IP address.If the unit was setup on the terminal currently in use, this value should not need to be changed.

4.10 Transfer Setup and Configuration Files to Units

Once the MCS Edit Data folders have been used to setup and configure unit OFDD.VHO files, these files must be uploaded to the units. The Maintenance Console Software can be used to perform this task.

To upload OFDD.VHO files to network units:1. Select the units for upload in the Units pane of the directory window.

To select a contiguous group of units, select the first unit clicking its name. Then click on the name of the last unit in the list while holding the shift key.To select non-contiguous group of units, hold the CTRL key and then click on the name of each unit to be selected.

• To perform the upload using the following Maintenance Console Software procedure, the unit setup parameters must have been previously uploaded to the unit using the Unit Information Setup Wizard's Upload Option. Also, the unit must be connected to the LAN as described in Section 3.4.*1

*1 Another method can be used to upload an OFDD.VHO file to a single unit; FTP/Telnet file transfer. See Appendix A7.

• Gateway and Gatekeeper configuration files can not be combined in a single file transfer operation.



2. Select the File Transfer item from the Units menu.The Maintenance Console Software displays the File selection dialogue box.

3. Use the mouse to click on the system file check boxes and configure all fields so that the only checked box is for Config file.

4. Click the radio button, Reboot after file transmission, so that the units will automatically be rebooted.

5. If desired, check the Log activity option to record a log of the transfer process. Use the radio buttons to have the file overwrite any existing log files or append the log data to the end of an existing file.

6. Click on the OK button to begin the file transfer. Click the Cancel button to abandon the file transfer process.

The Maintenance Console Software displays a confirmation dialogue box.

7. Click Yes to proceed with the transfer, or No to abandon the process.

• It is important that the Config. File option be the ONLY item checked.



When Yes is selected, a transfer status message is displayed showing the file transfer progress.

Once the transfer process is complete, the Maintenance Console Software displays a report.

The Configuration file column should show OFDD.VHO for each unit. All other columns should show a dashed line.

If the transfer process failed, the Configuration file column will show a value of NG (No Good). See the KX-TDA0480 Programming Guide, for a discussion of trouble shooting.



Once the OFDD.VHO files have been successfully transferred, each of the units must be rebooted to have the new configurations take effect.If the Reboot option was not selected during the file transfer process, the units can be rebooted using the Control/Reboot item on the Unit menu.



To reboot the units:1. Select the units for upload in the units pane of the directory window.

To select a contiguous group of units, select the first unit clicking its name. Then click on the name of the last unit in the list while holding the shift key.To select non-contiguous group of units, hold the CTRL key and then click on the name of each unit to be selected. The Maintenance Console Software displays a Reboot dialogue box allowing the reboot to be forced or causing the reboot to occur only after all in-process calls are terminated.

2. Click the radio-button for the desired option and click the OK button to proceed. Select the Cancel button to abandon the process.



The Maintenance Console Software then displays a list of units selected for reboot. The checkboxes in the list can be adjusted to reflect the units to be rebooted.

3. Configure the units to be rebooted if necessary and click the Execute button to proceed with the reboot. Select the Cancel button to abandon the process.

The Maintenance Console Software displays a confirmation dialogue box.

4. Click Yes to proceed with the transfer, or cancel to abandon the process.

Once the Maintenance Console Software completes the operation, a Reboot results list is displayed.The Result column should display OK. If Error is returned for a unit, there was a problem with the transmission. See the KX-TDA0480 Programming Guide, Trouble Shooting section.



4.11 Synchronise Unit Time and Date

If a unit is disconnected from a power source for two or more months, battery discharge may result in the loss of the unit's clock synchronisation. This condition can produce alarm indications that do not affect the operation of the unit, but should be corrected using the following procedure.The Time Sync item on the Unit menu is used to synchronise the KX-TDA0480's time and date with the time and date setting of the computer terminal with which the unit is connected.

To update the time and date settings for one or more units:1. Check that the time and date setting for the computer terminal is correct and reset the time

if necessary.

2. Select the Time sync command from the Unit menu.

3. The MCS displays a Time sync unit selection list.

4. If necessary, mouse-click on a Unit Name in the list box to select or deselect it for synchronisation.

5. Click the Execute button to proceed with the update. Click on the Cancel button to abort the process.



The MCS displays a message box showing the progress of the update and then displays a results list indicating if the process was successful for each of the selected units.

A1 Voice Over IP Addressing

The KX-TDA0480 relies on static IP addressing for communications between network devices. This means that networks in which all addressing is allocated on the basis of dynamic IP addressing (DHCP/BOOTP) are incompatible with the KX-TDA0480 technology. Hybrid systems capable of employing both static and dynamic addressing are capable of employing the KX-TDA0480 technology.All IP addressing must conform to Internet Protocol addressing standards. The diagram below illustrates IP addressing for the sample network used in this document.


Overall

SubnettingIP addressing defines subnetting. Each network location has a subnet mask address that helps to define which digits of an IP address are used for the network address and the host address. In this case the sample network, the subnet address is the KX-TDA0480 default, 255.255.255.0. The subnet mask addresses for various networks may differ from the default subnets. In the case of the Internet, the subnet mask address will be provided by the regulating agency or the IP address provider.

• The following discussion does not attempt to address the subtleties of IP addressing.

Units at each location have unique IP addresses. These addresses fall within the same subnet as that of the gateway shared by the units. This means that the KX-TDA0480 connected to the same gateway will share the network portion of their IP address with the Gateway.Units at each location have unique IP addresses. These addresses fall within the same subnet as that of the gateway shared by the units. This means that all KX-TDA0480 connected to the same gateway will share the network portion of their IP address with the Gateway.

In the sample network, the San Francisco and Los Angeles offices are using a Class C address space (255.255.255.0), which means that all but the final octet (0) must be the same for all devices. The final octet for the device address cannot use the values 0 or 255.

Unit IP AddressingIn the sample network, the IP addresses have been allocated so that each KX-TDA0480 has a sequential number. For example, at the New York office, are addressed in sequence so that the last element of the NY01 address is .91, NY02 is .92. This sequencing is for convenience only and is not a requirement of the addressing scheme.

Finally, each location in the sample network has only a single router. Of course, there may be more than one router at each location, and each must be servicing its own subnet.

A3 DNS Configuration

A3.1 KX-TDA0480 DNS Functions

The function of a DNS system in the KX-TDA0480 network is to provide telephone number to IP Address translations when an H.323 Gatekeeper is not used.The KX-TDA0480 is able to use DNS information from internal DNS Database (limit of up to 511 units in the Network)The KX-TDA0480 Internal DNS Database file (DNS.DAT) is located in the directory 3.1 / VHUB/ETC within each unit. This information is common to all units in the network and is used to set IP Gateway network "priority connections". Since the internal DNS information resides autonomously in each KX-TDA0480, it is necessary to update every unit's DNS configuration file whenever the network configuration is changed.

A3.2 KX-TDA0480 Internal DNS Database

The internal DNS.DAT file is a simple text based database file. Each line in the file is a record containing number translation information for the KX-TDA0480 in a network sharing the same domain.Within each record, fields are identified by a single letter. Following each field identifier, the field values are recorded.The fields in the DNS.DAT file are:

N = Called Unit Code (KX-TDA0480 Office Code).

R = Remaining digits to be dialled in order to complete a connection. (Up to 32 digits)

I = IP address and Connection port no. (It is possible to omit the value at 1720.) of destination KX-TDA0480

The following equipment is included in the network.

N 217: Specifies the extension number 7nn (R-value being 2: 700 - 799) of PBX Code 21 as a called destination.

N 219: Specifies the Access Code for PSTN access from the PBX Code 21. The R value is 10 (max 32) which allows the user to dial in a 10 digit PSTN number followed by any extension number for the user being called. For example, from CG01 the caller can call 21-9- 408-935-3303 and reach the person on (408) 935-3303 in the PSTN network.

• It is recommended that extensions for fax and PSTN be set separately.

Appendices

A4 Pad Control and AGC

PAD is a voice line gain/loss function expressed in decibels (dB). The KX-TDA0480 is able to insert a digital pad in the outgoing and/or incoming speech path in order to optimise the gain or loss level of the voice signal.

The KX-TDA0480's AGC (Automatic Gain Control) functions on the PAD In side in a manner similar to that of the PAD In function, but operates by automatically adjusting the voice signal to a preset level.

A4.1 PAD Controls

The default Pad settings can be modified by the user. This is usually done on a network-wide basis.

In most cases it should not be necessary to modify the default PAD In and PAD Out settings. Indications that some adjustment is required are:

The following issues should be considered when adjusting the pad control.

• The digital pad value for the KX-TDA0480 can be selected as -40,-38,c,-14, -12, -10, -8, -6, -4, -2, 0, +2, +4, +6, +8, +10, +12, +14 dB.

The unit default settings are:

PAD Out = 0 dB

PAD In = 0 dB

A4.2 AGC

When enabled, the AGC feature allows the KX-TDA0480 to adjust the voice signal strength to a predetermined level.

As a rule, it is recommended that the PAD In value be set to 0 dBm when using this feature.

Voice level too low: Increase gain by decreasing PAD level.

Voice loud/distorted: Decrease gain by increasing PAD level.

Excessive background noise: Decrease gain by increasing PAD level.


Appendices

A5 Optimising Performance

Although the features of the KX-TDA0480 go a long way toward assuring clear voice communications and error free fax transmission over digital data networks, some network conditions can cause performance degradations.

Common causes include:

• Voice PAD settings not correctly configured.

• Many collisions among packets within the Local Area Network (LAN).

• Number of hops packets go through is too large.

• High traffic conditions are prevalent on the network.

• Routing through a firewall.

• Wide Area Network (WAN) transmission delays.

• Internet Service Provider (ISP) has inadequate service characteristics.

The methods used to prevent problems and optimise performance depend on the type and configuration of the network equipment in use. Below are some suggestions that may prove useful.

A5.1 Voice Volume

In some applications, voice volume may be either too low or too high. The gain control feature operates on both the incoming and outgoing sides and is referred to as the PAD control. The KX-TDA0480 is able to optimise the gain or loss level of the voice signals.

In most cases, it should not be necessary to modify the default PAD In (PAD value of the voice signals coming in to the unit)/PAD Out (PAD value of the voice signals going out from the unit) settings. Indications that some adjustment is required are:

Voice level too low: Increase gain by decreasing PAD level.

Voice loud/distorted: Decrease gain by increasing PAD level.

Excessive background noise: Decrease gain by increasing PAD level.

See section 4.9.1 Configure Gateway Units (KX-TDA0480) for configuring this information in the KX-TDA0480.

A5.2 Transmission Delays

Transmission delays can cause pauses and loss in voice communications and may result in delays and loss of fax transmissions. These conditions typically arise when there are high traffic loads (congestion) on the LAN and/or WAN. In the case of the LAN, the network design affects performance. In the case of the WAN the local router, the link to the ISP (i.e., ISDN,


Appendices

FR, F/T1, and T1), and the Internet Service Provider (ISP) facilities also affect performance.

Transmission delays are caused by excessive packet collisions. The probability that this condition will affect the KX-TDA0480 performance can be minimised by taking steps to provide the KX-TDA0480 with clear transmission paths.

KX-TDA0480 LocationOne preventative measure is to install the KX-TDA0480 so that the number of transmission hops is kept to a minimum. In the figure below, the KX-TDA0480 is located as close to the WAN interface as possible.

Priority ControlSome routers permit the configuration of priority control features. This allows the router to be configured to give higher priority to packets with high priority flags.

The priority control feature should be used when available. The KX-TDA0480 port numbering for the various packet types is presented in the following table.

Recovery Delay and Jitter Buffer

The KX-TDA0480 supports a secondary Jitter Buffer that activates in a dynamic manner. The following parameters can be programmed. This feature can be configured to help compensate for network congestion problems.

• Maximum Receive Buffer Size, defines the size of Jitter Buffer (max 1920ms).

• Start Recovery specifies the discard packets process limit once denoting that the buffer is full.

• End Recovery defines the limit beneath which the buffer continues to discard packets until the setting is reached.

The following diagram illustrates how the buffer process works.

Internet, Intranet, and Virtual Private Networks (VPN)

Managed Networks (Intranet, Leased Lines, VPN, etc.) provide better quality of service as compared to unmanaged networks (e.g., the Internet).

When implementing a network of the KX-TDA0480, care must be taken when assessing bandwidth requirements. The KX-TDA0480 uses 12K per port when in use. Serialisation delays to the WAN are lower when higher bandwidths are used.

When using the Internet/VPN, the Internet Service Provider plays an important role in reducing the variable delay in the WAN. A regional or national ISP will usually have better connectivity with the backbone and will be able to guarantee greater service reliability than a local city ISP.

When using VPN facilities, delays may be introduced due to the additional processing time required for encryption processing.


Appendices

A5.3 Firewalls

It is generally preferable that a IP Gateway network installation be connected with the IP network outside of any existing firewall installation. When for practical or policy reasons, an installation must be routed through a firewall some performance degradation may occur.

In the above example, the KX-TDA0480 is routed through a firewall. The Router IP address no longer serves as the KX-TDA0480’s Default Gateway IP address. Instead, the internal IP address of firewall becomes the Default Gateway IP address to be associated with the KX-TDA0480.

Also, when installing the IP Gateway network within a firewall, voice and fax packets must be routed through specified firewall ports using the information in the following table.

A6 Configuration Files

The KX-TDA0480 OFDD.VHO configuration files are stored as plain text files and can be edited directly using a plain text editor on any computer device. For experienced planning and installation personnel, this method can be fast and efficient. Once files have been created, they can be uploaded directly to the KX-TDA0480 using the FTP method discussed in Appendix A7.Once an OFDD.VHO file has been manually modified, the MCS unit registration information will be no longer be synchronised. Therefore, it is recommended that the modified OFDD.VHO file not be reopened directly using the MCS. If it is necessary to establish conformance with the MCS, establish a LAN link with the unit. Next create a new unit using the MCS Setup Wizard (Section 4.7 Create New Units), using the IP addressing information for the unit. Finally, select the download option when configuring the unit (Section 4.7 Create New Units) and download the configuration data directly from the unit. The manually created settings will then appear in the MCS configuration folders.

Also, when working directly with configuration files it is very important to observe and comply with the directory structure used by the Maintenance Console Software. Any change to this structure will cause the MCS to fail.

The OFDD.VHO files for each group are located in the unit sub-directories for each group. The Group directories are Chicago, Los Angeles, New York, and San Francisco.. Within each group are the Unit directories using the Unit Names (e.g., NY01, NY02, etc.) Note the location of the _tone_current file and Tone sub-directory.

Note the two OFDD files, OFDD.VHO and OFDD.OLD. The file with the .VHO extension is the current version.

A7 FTP File Transfers

Although the Maintenance Console Software provides file transfer tools, it is sometimes quicker to upload and download files over a network connection using the KX-TDA0480's FTP file transfer capabilities. This is especially true when updating a IP Gateway network's internal DNS settings.

DNS.DATThe KX-TDA0480's DNS.DAT file can be uploaded and downloaded using an FTP connection.*1 Since the DNS.DAT file must be common to the KX-TDA0480 in a network, this technique can be very useful.

A DNS.DAT file can be downloaded from a unit and then edited manually for a configuration update.

An updated DNS .DAT file created and saved either manually or with the Maintenance Console Software, can be uploaded to units in the network.

OFDD.VHOThe KX-TDA0480's OFDD.VHO file can be uploaded and downloaded using an FTP connection. This capability may be useful when manually configuring a large number of units. In this case, experienced installers can download a OFDD.VHO file, manually edit its configuration parameters for another unit, and then upload the new configuration file to the new unit.

A OFDD.VHO file can be downloaded from a unit and then edited manually.

A manually edited OFDD.VHO file created and saved either manually or with the Maintenance Console Software, can be uploaded to a unit in the network.

WARNINGThe commands discussed in the following procedures are CASE SENSITIVE. Please be careful to use the proper case when entering FTP commands and the KX-TDA0480 file names.

Local Area NetworkA short distance data communications network used to link together computers and peripheral devices (such as printers) under some form of standard control.

JitterJitter refers to fluctuations in transmission delay time. In the case of voice data, conversations are packaged into packets (IP packetisation) and transmitted. Individual packets can take different routes through the varied networks that comprise the Internet. When the time interval for the arrival of the packets is not constant the timing fluctuations that may occur are referred to as "jitter".


Glossary

Line dataLine data is a category of office data that includes both terminal and trunk data.

MCUMultipoint Control Unit. A bridging or switching device used in support of multipoint videoconferencing and supporting as many as 28 conference sites.
