scope:

Next generation technology [i.e., Internet Protocol (IP)] reflects the ongoing evolution of the Public Switched Telephone Network (PSTN). Historically, the PSTN has been based on Time Division Multiplexing (TDM) equipment and processes as the backbone of the network. As the industry transitions, IP technology provides an alternative means for voice and data transmission and the potential for many new services and processes (i.e. TN authentication frameworks). However, the transition, and ultimately IP technology, presents a need to address its impact on telephony functions and processes that have been developed over time in order for calls to be reliably completed. These are related to such functions as network reliability, operational efficiencies, intercompany interconnectivity, network/call troubleshooting, and many other areas that permit networks to interwork with each other consistently and effectively.

Within the wide scope of IP related impacts, this document focuses on providing information for connecting service provider (SP) networks using next generation connections, including internetwork routing.

As industry standards, best practices, and regulatory decisions relative to IP become further defined, this document will be modified as applicable.

Purpose

This document serves as a guide to provide an industry understanding of the operational needs for next generation interconnection and interoperability.
