|
|
Name:
|
ETSI TS 126 071 V6.0.0 (2004-12)
|
|
Title:
|
Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); AMR speech Codec; General description (3GPP TS 26.071 version 6.0.0 Release 6)

Status of approval:
|
|
|
Standard

|
Justification for the specific reference:
|
|
|
The AMR, which is one of recommended codecs in clause 14.2.2 of Y.2201(2009), is specified by ETSI TS 126 071, and there is no equivalent specification within any ITU-T recommendations. Since all specifications in ETSI TS 126 071 are necessary to specify the AMR, referencing is appropriate.
