Multiple access for BISDN

Some possible access scenarios for broadband ISDN based on asynchronous transfer mode (ATM) switching are examined. The use of existing or emerging networks such as local area networks (LANs) or metropolitan area networks (MANs) as access networks is discussed. These networks are well suited for the data-oriented information that is seen as the first main application in the BISDN. Following the geographical extension of existing LAN applications, multimedia is generally seen to be a very important broadband application. Possible access schemes based directly on ATM cells and not restricted to a specific service are then considered. The status of the discussions in the International Consultative Committee for Telephone and Telegraph (CCITT) on generic flow control, which has a close relationship to ATM-based networks in the customer premises, is summarized.<>
