`
`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 second edition, has been produced as a result of further updating work carried out by TC-SMG
`on the base document GSM 08.60.
`
`This ETS specifies the inband control of remote transcoders and rate adaptors for full rate speech and full
`rate data within the European digital cellular telecommunications system (Phase 2).
`
`This ETS corresponds to GSM technical specification, GSM 08.60 version 4.2.0.
`
`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.

`
`Introduction
`
`1.1. Scope
`
`When 64 kbit/s traffic channels are used on the Abis interface the speech shall be coded according to
`CCITT Recommendation G.711 and the data rate adaption shall be as specified in TS GSM 04.21 and
`TS GSM 08.20.
`
`In the case where 16 kbit/s traffic channels are used for full rate speech or full rate data service, then this
`specification shall apply for frame structure and for control of remote transcoders and additional rate
`adaptors.
`
`The use and general aspects of the Abis interface are given in TS GSM 08.51.
`
`NOTE:
`
`This specification should be considered together with the GSM 06 series of
`specifications, TS GSM 04.21 (Rate Adaption on the MS-BSS Interface) and TS GSM
`08.20 (Rate Adaption on the BS/MSC Interface).
`
`1.2. Normative references
`
`This ETS incorporates by dated and undated reference, provisions from other publications. These
`normative references are cited at the appropriate places in the text and the publications are listed
`hereafter. For dated references, subsequent amendments to or revisions of any of these publications
`apply to this ETS only when incorporated in it by amendment or revision. For undated references, the
`latest edition of the publication referred to applies.

`
`General Approach
`
`When the transcoders/rate adaptors are positioned remote to the BTS the information between the
`Channel Codec Unit (CCU) and the remote Transcoder/Rate Adaptor Unit (TRAU) is transferred in
`frames with a fixed length of 320 bits (20 mS). In this specifi cation these frames are denoted "TRAU
`frames". Within these frames both the speech/data and the TRAU associated control signals are
`transferred.
`
`The Abis interface should be the same if the transcoder is positioned 1) at the MSC site of the BSS or if it
`is positioned 2) at the BSC site of the BSS. In case 1) the BSC should be considered as transparent for
`16 kbit/s channels.
`
`When data is adapted to the 320 bit frames, a conversion function is required in addition to the conver-
`sion/rate adaption specified in TS GSM 08.20. This function constitute the RAA.
`
`The TRAU is considered a part of the BSC, and the signalling between the BSC and the TRAU (e.g.
`detection of call release, handover and transfer of O&M information) may be performed by using BSC
`internal signals. The signalling between the CCU and the TRAU, using TRAU frames as specified in this
`specification, is mandatory when the Abis interface is applied.
`
`NOTE:
`
`If standard 64 kbit/s switching is used in the BSC, multiplexing according to CCITT
`Recommendation I.460 should apply at both sides of the switch.
`
`In figure 2.1 a possible configuration of the TRAU and the CCU is shown.
`
`The functions inside the TRAU are:
`
`"Remote Transcoder and Rate Adaptor Control Function" (RTRACF);
`"Remote Speech Handler Function" (RSHF);
`The RAA function;
`The RA2 function;
`The transcoder function.

`
`The functions inside the CCU are:

`The RAA function;
`The RA1/RA1' function;
`The channel codec function.

`
`This specification will not describe the procedures inside the TRAU and the CCU. The layout in figure 2.1
`is only intended as a reference model.

`3.5. Coding
`
`In the following sections the coding of the frames is described. Any spare or not used control bits should
`be coded binary "1".
`
`For all frame types the octet 0, 1 and the first bit of octets 2, 4, 6, 8, ... 38 are used as frame sync.
