Rapporteur:  BARRETT, Paul
Descendant(s):  TS 46.042    


This TS specifies the Voice Activity Detector (VAD) to be used in the Discontinuous Transmission (DTX) as described in 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.
