G500:1998 Specification - Signalling System No 7 - Interconnect ISUP
This specification and its supplementary documents are part of the suite of documents developed for the purpose of defining the interconnect services and signalling protocol that will be available from interconnecting domestic Australian networks.
G500:1998 and its supplementary documents were improved to produce G500:2000 and G549:2000 . G500:2002 Specification - Interconnect Signalling Specification for Circuit Switched Networks is based on the ITU's ISUP 2000 and related ETSI specifications and may also be of interest.
