Table 9-1 BISUP Parameter Inclusion

Details messages, methods and parameters of the BISUP of SS7 for control of ATM SVCs. Inclusive of methods to support calls routed to or received from an interconnecting network e.g. an Interexchange carrier network. Requirements are given for BISUP signaling using both the quasi-associated and associated mode of signaling. The signaling methods relate to point-to-point and point-to-multipoint constant and variable bit rate connections. BISUP methods to handle ATM and AESA are also given. Includes requirements related to the interworking between the access protocol DSS2 and BISUP. Including the support of 64 kbit/s based narrowband circuit-mode services - speech 3.1-kHz audio and 64 kbit/s unrestricted digital information bearer capabilities and interworking of these services with narrowband networks using ISUP
