'ISDN BASIC ACCESS TECHNIQUES'

摘要

Various implementation approaches have been undertaken to develop an LSI/VLSI chip set suitable for CCITT-ISDN basic access applications (144 Kbit/s net-rate).First we review the main objectives that should be met by such implementations in terms of cost-effectiveness versus satisfaction of potential applications.These include:Terminals,Network Terminations,Central Office Subscriber Interface Boards,PABX Subscriber Interface Boards.
