ABSTRACT: This document replaces TA-NWT-001358.

This Technical Reference (TR) provides quantitative benchmarks on the overload controlled switching system throughput (i.e., successfully processed call attempts), along with the quantitative description of the overload-related characteristics of offered traffic (traffic volume and customer behavior).

These generic requirements supplement and enhance GR-505-CORE, LSSGR: Call Processing, Section 5, which stipulates that the primary objective of overload controls on a switching system is to maintain throughput of successful calls regardless of the extent or cause of the overload. A key requirement of this document is that the overload throughput should not fall below 90% of the engineered capacity, if the overload does not exceed 30% in terms of the first attempts.
