Transmission systems for the BISDN

Subscriber access capacity corresponding to the first level of the synchronous digital hierarchy (SDH), which has been agreed upon as an international standard for broadband ISDN, is discussed. The subscriber access reference configuration defined by the International Consultative Committee for Telephone and Telegraph (CCITT) is described, as is the structure of the transmission network. Suggested transmission systems or systems already implemented are then examined. The discussion covers asynchronous transfer mode, multiplexing and framing, trunk line systems, subscriber line systems, optical transmission, and TV distribution.<
