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 the next review is scheduled to occur in 2020.
