In detail what are the features operations and revelantant standards of ISDN.I have some information allready like
Integrated Services Digital Network is a set of digital transmission protocols defined by CCITT. The protocols are accepted by virtually all the world’s communications carriers as standard.
o It builds on groups of standard transmission channels. Bearer channels (or B channels) transmit user information at relatively high speeds, while separate Data channels (or D channels) carry call set-up, signaling and other information.
Two types of ISDN channels. B channels are clear channel "pipes" for user voice and data.
D channels are packet-switched links for call set-up and user data.
o It handles all types of information. Unlike some other digital communications technologies, ISDN handles all types of information - voice, data, studio-quality sound, still and moving images. They are all digitized, and transmitted at high speeds in the same flow of data.
