Abstract :
Call processing for establishment of switched virtual connections (SVCs) in ATM networks builds upon the existing models of call establishment for circuit-switched narrowband networks. This paper describes the application of the intelligent network´s capability set-2 (IN CS-2) basic call state model (BCSM) to the call processing software of an ATM switch. The call control function (CCF) that implements the BCSM makes use of the ATM Forum´s semantic API to communicate with the switch network services. We show how the high level “telephony-style” BCSM and its points-in-call (PICs) are mapped to the “data/socket-style” native-ATM connection states as described in the semantic API specification
