Introduction
This service description document details the Inband SignalingProtocol between Transcoder/Rate Adapter Units (TRAU) for speechtraffic channels for the Tandem Free Operation (TFO) of SpeechCodecs, sometimes also termed “Vocoder Bypass”. It is applied tothe North American standard TIA/EIA/IS-2000-A.
Annex A is mandatory and defines the capability and requirementsused in the development of this TFO standard.
Annex B is mandatory and describes the general Inband Signaling(IS) Principle, which is applicable to TFO specifications for allsystems (e.g., TIA/EIA-136, TIA/EIA/IS-2000-A, GSM) and onlyupdated to include the System Identifications for TIA/EIA-136 andTIA/EIA/IS-2000-A.
Annex C is informative and gives the rules for In Path Equipment(IPE). It is identical for all systems (e.g., TIA/EIA-136,TIA/EIA/IS-2000-A, GSM).
