Rapporteur:  Mr. Barrett, Paul
Antecedent:  TS 06.42    

This TS specifies the Voice Activity Detector (VAD) to be used in the Discontinuous Transmission (DTX) as described in GSM TS 06.41. It also specifies the test methods to be used to verify that a VAD implementation complies with this TS.

The requirements are mandatory on any VAD to be used either in GSM Mobile Stations (MS)s or Base Station Systems (BSS)s that utilize the half rate GSM speech traffic channel.
