scope:

This document specifies the procedures to be employed to verify that implementations of VAD processing in conjunction with the IS-641 DTWCNG feature meet strict minimum performance requirements.

This document describes the test database, a method for generating individual test data files, the test requirements on candidate VADs, a method to collect performance metrics, and a means to test those metrics so as to validate conformance to the specification.

The purpose of this standard is to define minimum performance levels for the VAD; however, the manufacturer should attempt to provide the highest possible level of performance.
