Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS specifies the comfort noise aspect for full rate speech traffic channels for the European digital
cellular telecommunications system (Phase 2).
This ETS correspond to GSM technical specification, GSM 06.12 version 4.0.4.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM Technical Specifications (GSM-TSs) (NOTE).
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system.
Historically, these documents have been identified as GSM Technical Specifications
(GSM-TS). These TSs may have subsequently become I-ETSs (Phase 1), or ETSs
(Phase 2), whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are,
for editorial reasons, still referred to in GSM ETSs.

0.1 Scope
This technical specification gives the detailed requirements for the correct operation of the background
acoustic noise evaluation, noise parameter encoding/decoding and comfort noise generation in GSM
Mobile Stations and Base Station Systems during Discontinuous Transmission (DTX) on full rate speech
traffic channels.
The requirements described in this technical specification are mandatory for implementation in all GSM
Mobile Stations. The receiver requirements are mandatory for implementation in all GSM Base Station
Systems, the transmitter requirements only for those where downlink DTX will be used.
0.2 Normative references
