Abstract (en)
[origin: WO0062494A1] The narrowband DS0 circuit ID and the called party address of a narrowband call SETUP request received by an ATM switch are used by the switch to identify a virtual channel profile (VCPRO) and a broadband address (BBA) (210). The VCPRO and BBA are then compared to teh VCPROs and BBAs of all existing calls which are carried by SVCs and serviced by the switch in order to determine whether or not a suitable existing SVC is presently set up which can carry the call to the termination endpoint of the call (220). If such an SVC exists (230), a connection admission control (CAC) is run on the SVC of that call in order to determine whether sufficient bandwidth to carry the requested call is available on that SVC (240). If sufficient bandwidth is available (250), the call is accepted, placed into the SVC, and the details of the call, are entered into the active call structure table (260). If sufficient bandwidth is not available, or if no suitable existing SVC is available, a new SVC is set up between the switch and the destination switch, or the call is rejected (225).
