  • ISDN) the ISDN
    Lecture-3 Integrated Services Digital Network (ISDN) The ISDN • The standards for ISDN was defined and developed by ITU-T in 1976. • Set of protocols that combines digital telephony and data transport services. • The whole idea is to digitize the telephone network to permit the transmission of audio, video and text over existing telephone lines. • The goal is to form a WAN that provides universal end- to-end connectivity over digital media. Integrated Digital Network (IDN) • A combination of networks available for different purposes. • Access to these networks is by digital pipes • Digital pipes are time-multiplexed channels sharing very high speed paths. Integrated Services Digital Network (ISDN) • ISDN incorporates all communication connections in a home or building into a single interface. • With ISDN all customer services will become digital rather than analog. Principles of ISDN 1. Support of voice and non-voice applications using a limited set of standardized facilities – Defines the purpose of ISDN and the means of achieving it 2. Support for switched and non-switched applications – Both circuit-switched and packet-switched connections – Support non-switched services in the form of dedicated lines 3. Reliance on 64-kbps connections – Fundamental block of ISDN – 64 kbps were chosen because it was the standard rate for digitized voice 5 Principles of ISDN 4. Intelligence in the network – Sophisticated serviced beyond simple setup a circuit-switched call – Sophisticated network management and maintenance capabilities – Use of SS7 (signaling system 7) and intelligent switching nodes in the network – SS7 is a set of telephony signaling protocols which are used to set up the vast majority of the world's PSTN telephone calls.
