Integrated Service Digital Network

PRINSIP ISDN

Prinsip ISDN :

1.Mendukung aplikasi suara dan non-suara

2.Mendukung aplikasi switched dan nonswitched

3.Ketergantungan terhadap koneksi 64-kbps

4.Kecerdasan dalam jaringan

5.Arsitektur protokol berlapis

6.Macam-macam Konfigurasi

KONSEP DASAR ISDN

Integrated Service Digital Network

KEUNTUNGAN ISDN

Integrated Service Digital Network

• High Speed & Quality> 10 kali lebih cepat dari PSTN ( > 9,6 Kbps )

• EfficiencySatu saluran untuk berbagai jenis layanan (voice, data

dan video)

• FlexibilitySingle interface untuk terminal bervariasi

• Cost EffectiveTeminal tunggal untuk audio dan video

MODEL REFERENSI ISDN

USER INTERFACE ISDN

Integrated Service Digital Network

• TE1 Contoh : Telepon ISDN; Video phone.

• TE2 Contoh : Telepon konvensional ( terminal a/b ) Terminal X-25.

• NT1 Contoh : titik terminasi fisik 2 kawat ke 4 kawat

• NT2 Contoh : PABX; LAN

• LT LT dapat membentuk fungsi-fungsi seperti NT, test loop, pembangkitan sinyal dan konversi kode.

• ET :Titik terminasi jaringan akses dg sentral ISDN dimana sinyal kontrol diproses.

USER INTERFACE

USER INTERFACE

Integrated Service Digital Network

• Network Termination (NT)NT bisa berupa Modem atau perangkat PBX

• Terminal Equipment 1 (TE1)Contoh : Telepon digital, Fax G4, Videophone

• Terminal Equipment 2 (TE2)Contoh : PC, FAX analog (G3), Telepon analog

• Terminal Adapter (TA)

Perangkat interface terminal non-ISDNU-Interface

2-W subscriber line• S/T-Interface

4-wire physical interface, untuk koneksi antara NT dengan TE1 atau NT dengan TA.

• R-Interface

Physical interface antara TA dengan TE2
