This document describes the Source Controlled Rate (SCR)operation of the Adaptive Multi-Rate speech Codec in Codec Types UMTS_AMR and UMTS_AMR2 for the UMTS system. The implementation of this SCR operation is mandatory in all UMTS equipment. The description is structured according to the block diagram in figure 1. This structure of distributing the various functions between system entities is not mandatory for implementation@ as long as the operation on the speech decoder output remains the same. Annex A describes the Discontinuous Transmission (DTX) operation of the Adaptive Multi-Rate speech Codec in Codec Types FR_AMR@ HR_AMR and OHR_AMR for GERAN. This annex is the former GSM 06.93 (Release 98). Annexes B to E describe the SCR operation of the Adaptive Multi-Rate speech Codec in Codec Types GSM_EFR@ TDMA_EFR@ TDMA_US1 and PDC_EFR for the UMTS system.
