G520:2005 Local Number Portability - Network Plan
Defines the call handling and technical interconnection arrangements for local number portability, based on a model of interconnected networks. The model of interconnected networks is derived from AUSTEL's Interconnection Model of March 1995. The Plan also provides a description of the initial solutions being used for providing local number portability in Australia.
This Specification was reconfirmed in 2015 and 2020 and the next review is scheduled to occur in 2025.
