Amdt No. 1/2020 to ACIF G500:2000 (.pdf, 62 KB)
Defines the interconnection services and signalling protocol to be available for interconnecting domestic Australian networks.
Amendment No.1 of 2020 allows the transfer of international CLI.
The Specification was reconfirmed in 2007, 2012 and 2017 and amended in 2020. The next review is scheduled to occur in 2025.
Other related documents include:
G549:2000 Interconnection Implementation Plan (this complements G500:2000)
G500:1998 Specification - Signalling System No 7 - Interconnect ISUP (this was improved to produce G500:2000)
G500:1998 Supplement is the supplementary documents to G500:1998. It contains a number of service descriptions and the interconnect dial plan which was the predecessor to 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.
G500:2002 Specification - Interconnect Signalling Specification for Circuit Switched Networks
G500:2002 specifies the interconnect services and signalling protocol that will be available from interconnecting domestic Australian circuit switched networks.
This Specification has been withdrawn.
G500:2000 and G500:1998 are separate versions of signalling specifications for the interconnection of circuit switched networks in Australia. At the time of publication of G500:2002, inter-network interfaces based on either G500:1998 or G500:2000 were in operation and might continue to be used indefinitely.
G549:2000 Interconnection Implementation Plan
Amdt No 1/2020 to ACIF G549:2000 (.pdf, 63 KB)
Specifies the recommended technique for passing information between networks that is necessary for end-to-end operation but is not included in the signalling elements of the Interconnection ISUP Specification.
Amendment No.1 of 2020 supports the transfer of international CLI.
The Specification was reconfirmed in 2007, 2012 and 2017 and amended in 2020. The next review is scheduled to occur in 2025.
Other related documents include:
- G500:2000 Interconnection ISUP (this complements G549:2000)
- G500:1998 Specification - Signalling System No 7 - Interconnect ISUP (this was improved to produce G500:2000)
- G500:1998 Supplement is the supplementary documents to G500:1998. It contains a number of service descriptions and the interconnect dial plan which was the predecessor to G549:2000.
- G549:2002 Interconnection Implementation Guideline may also be of interest. It provides information on the consistent implementation of interconnection signalling based on G500:2002 and interworking between G500:2000 and G500:2002.
- G500:2002 Specification - Interconnect Signalling Specification for Circuit Switched Networks is based on the ITU's ISUP 2000 and related ETSI specifications and may be of interest if using G549:2002 instead of G549:2000.
