B-ISDN signalling protocol capabilities

Abstract

The authors outline B-ISDN (broadband integrated services digital network) protocol requirements and clarify necessary signaling protocol functionalities for each service phase. For broadband-specific services they propose mechanisms to control multipoint communication. Discussed is the integration of user-network and interoffice interface signaling, particularly the replacement of SS7 by DSS1. A new protocol structure for various multipoint services is described. A call control architecture with modularized protocol structure which includes basic and enhanced control modules is proposed.<>
