G549:2000 Interconnection Implementation Plan

G549:2000 (.pdf, 273 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.

  • 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.
