Tiga Jenis Public Data Network yang kita kenal berdasarkan geografis adalah:

1. LAN (Local Area Network) Biasanya terbatas luasnya, misalnya bangunan atau ‘kampus’ Kecepatannya berkisar antara 4 Mbps sampai >100 Mbps Dimiliki dan dikelola sendiri Dalam bisnis dewasa ini merupakan suatu keharusan

2. MAN (Metrpolitan Area Network) Hubungan antar lokal area network di suatu kota atau melalui

suatu kampus. MAN Bisa disebut juga sebagai extention dari LANs Bersifat individual user Umumnya digunakan untuk mengirim trafic pembicaraan dan

data Terdapat dua standard Yaitu FDDI II ( Fibre Distribution Data

Interface) dan IEEE 802.6 ( Institution of Electrical and Electronic Engineers, USA)

Kecepatan bisa 100 MBps dan 150 MBps.


3. WAN (Wide Area Networks) WAN dikenal sebagai hubungan antar Komputer /Terminal yang

bersifat inertcity, intercounty dan intercontinental. Atas dasar infra struktur komunikasi dapat dibagi dalalm

Terrestrial Data Networks (TDNs) dan Satellite Based Data Networks (SBDNs)

Wide Area Network

Metroplitan Area Network

b. Broadband dan Penggunaan Fiber optic

Pertimbangan penggunaan Broadband1. Penggunaan bisa sharing akan memberikan keuntungan secara ekonomis.dan layanan yang fleksibel.2. Kebutuhan kanal secara individu memudahkan penyaluran

informasiyang diinginkan.

Dua jenis akses dan tiga area network yang dapat disajikan dalam komunikasi jenis ini :

a. Integrated Digital Access (IDA)b. Optical fiber dalam LANc. Local Area Networks (LAN)d. Metroplitan Area Networks (MAN)e. Wide Area Netwroks (WAN)

Keuntungan fiber optic :

Meningkatkan reliability Kappasitas Transmisi lebih besar. Redaman sangat rendah dan bebas dari Crosstalk

Saingan media transmisi bagi fiber optik antara lain yang paling dekat adalah coaxial cable dan yang paling serius dalam arti dapat dengan mudah dalam implementasi dan fleksibilitasnya adalah Wireless (Radio).

Information about Information about Internet Business StrategiesInternet Business Strategies


Two Different Internet Business Strategies

Strategies of Existing Carriers Transition to Internet Service Providers based on the

existing infrastructureInstall Internet POP at Central OfficeMaximize the network management, traffic control, and

billing capabilitiesSeamless Integration of the existing infrastructure

Keep the existing Users, Reduce the risks for new servicesService differentiation using Guarantee GoS/QoS,

ReliabilityProvide VPN services based on access control, traffic

control, and securityStrategies of New Carriers

Based on cost competitiveness strategiesMinimize the network construction cost

Deployment by Best Effort NetworkNo Service quality, no traffic control, minimum network

management, flat billing


Impact of Internet on Traditional Public Network - Market Perspectives

Internet is highly accepted as Information Platform by Users and Content Providers regardless of Reliability and Guaranteed QoS problemsTelco is interest in leveraging tremendous Investments for Internet to enable a Seamless Migration to Network of Tomorrow

Convergence by integrating Existing Network, IMT-2000, and InternetBuild Seamless Converged Multimedia Services to network of tomorrow


Impact of Internet on Traditional Public Network - Network Perspectives

Traffic Problems for packet transport using Existing Circuit - Switched

NetworkCongestion due to high volume POP trafficHigh penetration ( > 15 %) of Internet users Performance degradation for long holding time of 20 min.

Strategies to overcome Traffic ProblemsUsing external xDSL devices to divert the Internet trafficControlling Internet traffic reuse installed infrastructure to online

Toward Converged Networks

Voice/Data Convergence to facilitate the development of new types of applicationsIntegrated Email/Voicemail, screen pops, CTI,

etc.New converged VoIP system will replace traditional

PBXProblems of the PBX-based Convergence

PBX is a Part of Telecom for corporate administrative service, separated from user organization

Hard to innovative from business standpoint, keep the bill down

Not responsive to user requests for new servicesNot open, additional features only by PBX

vendor, all intelligence inside PBXFor CTI interface, the environment is complex

and vendor-specific


Backgrounds of Converged Networks

BackgroundsDemand for long distance calls at low cost/low qualityLocal Exchange Carriers provide long distance service

without expensive backbone infrastructure investment

Reduce transmission network costs with voice compression

Usage of low-cost Internet resourcesPC become a Multimedia Network Terminal

Current IssuesVOIP subscribers is not restricted to Internet users,

possible to reach Telephone Users everywhereInteroperability of VoIP

Incomplete standards solved by ITU, IETF, ETSI (TIPHON)


Advantages of Converged Networks

Advantage for Telco ISP to provide VoIPWith existing switching facilities,

Advanced VoIP service can be provided (e.g., simplified access authentication,

charging methods)Benefits concerning subscription,

authentication, call set up (few digits, more speed), and charging (e.g. advice

of charge)Keep the users in their own network

New low-cost services for new customers

Broadband services Broadband services didefinisikan sebagai “layanan telekomunikasi yang membutuhkan kanal transmisi lebih besar dari 2 Mbps (E1)”Atau: Jaringan digital yang dapat melayani apa saja: jasa data kecepatan tinggi, videophone, videoconference, transmisi grafis resolusi tinggi, CATV, termasuk juga jasa sebelumnya seperti telepon, data, telemetri dan faksimile

Narrowband ServicesNarrowband services didefinisikan sebagai layanan telekomunikasi yang membutuhkan kanal transmisi yang relatif senpit bandwidthnya atau lebih kecil dar 2 MB/s.

Bandwidth Bandwidth didefinisikan sebagai kemampuan kanal yang dapat melalukan data dengan kecepatan tertentu.Dalam sirkit dijital besarannya diukur dalam Bit Per Second (Bp/s) yang biasa disebut denga kecepatan transmisi. Untuk sistem analog diukur dengan Hertz (Cycle per second)

ISDN TLP


ISDN digunakan karena pada switching digital umumnya terjadi pergerakan signal 64 Kb/s dari satu lintasan signal 2Mb/s ke lintasan lain, selain dari pada itu content yang terdapat pada 64 Kb/s dapat berupa speech, data atau video.

Dengan sistem ISDN memungkinkan Customer melalui kabel tembaga mengirim berbagai signal pada jaringan switching telephone pada rate 64 Kb/s. Jadi dengan cara itu ISDN dapat memberikan pertukaran informasi dari Customer Premises yang satu kepada Customer Premises lainnya dengan sistem switching

64 Kb/s.


Terdapat 2 jenis access layanan ISDN 1. Basic Rate Interface (BRI) atau Basic Rate

Access (BRA) dikenal dengan 2B+D Sistem ini terdiri dari 2 bearer 64 Kb/s untuk

transmisi informasi dan 1 kanal signaling 16 Kb/s, digunakan unutk hubungan yang sederhana.

2. Primary Rate Interface (PRI) atau Primary Rate Access (PRA) dikenal dengan 30B+D yaitu terdiri dari 30 bearer channels pada rate 64 Kb/s dan 1 signalling cahnnel 16 Kb/s, umumnya digunakan untuk sistem yang lebih kompleks misalnya beberapa PABX dan hubungan komputer dengan kapasitas besar.

INTELLIGENT NETWORK

An Intelligent Network consist of a number of basic elements, the switching and transmission facility to carry the call traffic. The additional part of IN are :

1. Additional processing associated with the basic switch.2. Information resourcesthat are necessary for the provision

of special features.3. Service contreol facility that control the provision

ofspecial features and services- the basic network and the information resources are used to provide these services.
