Network Evolution

PSTN Transition Focus Group (PSTNTran-FG)

ATIS’ Technology and Operations Council established the PSTN Transition Focus Group to assess issues related to this evolution, and provide guidance on critical network transition challenges. In its work, the PSTN-FG assessed challenges based on four key areas associated with the evolution: application services, access, transport and numbering. Work set forth in the report’s recommendations will progress initially through ATIS’ Packet Technologies and Systems Committee, which develops and recommends standards and technical reports related to services, architectures, and signaling, in addition to related subjects under consideration in other North American and international standards bodies.

The PSTN Transition Focus Group Assessment and Recommendations is available for purchase from the ATIS Document Center — a leading resource for worldwide technical operations standards for communications technologies produced by ATIS Committees and Forums. Additionally, ATIS' recent webinar, Network Evolution - PSTN in Transition is available for complimentary on-demand viewing.
