23、103 version 14.0.0 Release 141 Scope The present Technical Specification outlines the Codec Lists in 3GPP including both systems, GSM and UMTS, to be used by the Out of Band Transcoder Control (OoBTC) protocol to set up a call or modify a call in Transcoder Free Operation (TrFO) and in “transcoder a
24、t the edge“ scenarios. The TS also specifies the SDP description of 3GPP Codecs to be used within a SIP-I -based circuit switched core network as specifies in 3GPP TS 23.231 14. The TS further specifies the coding of the Supported Codec List Information Elements for the UMTS radio access technology.
25、 The TS further reserves the Code Point for the CSData (dummy) Codec Type for the negotiation of A-Interface Type and the RTP redundancy for CS Data and Fax services, see 3GPP TS 48.008 23. The Supported Codec List IE includes Codec_Types from the TDMA and PDC systems, to support TFO or TrFO between
26、 UMTS and TDMA, or UMTS and PDC. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-s
