ABSTRACT: This document replaces TR-NWT-001364.

This Generic Requirements (GR) document provides the view of Telcordia on switch processing time requirements. It describes a methodology for categorizing the various types of switch processing, and specifies mean and 95% values as requirements for each of these categories.

The switch processing time requirements apply to various disciplines including Advanced Intelligent Network (AIN), Common Channel Signaling (CCS), Integrated Services Digital Network (ISDN) Access, MultiFrequency (MF) signaling, and operator services. Switch processing times are important performance characteristics because they represent the switches' contribution to the delays that telecommunications end users perceive. In fact, throughout the various phases of an end user's involvement in a call, the switch processing times are one of the largest contributors to delays that the end user may perceive.
