Provides Bellcore's view of generic requirements for an Asynchronous Transfer Mode (ATM) Service Access Multiplexer (SAM) to support broadband services such as SMDS Frame Relay, Cell Relay, native mode LAN interconnection and DS1/DS3 Circuit Emulation. A SAM is meant to be the element at the edge of a public ATM network to give a cost effective broadband service access platform. Its basic function is to aggregate traffic from multiple broadband service access interfaces and to deliver this service traffic to a BSS for service feature processing and switching. By aggregating traffic to provide a highly filled interface to a BSS a SAM may be viewed as the broadband services' analog of a remote digital terminal.
