13、 May 1996 Foreword This Global System for Mobile communications Technical Specification (GTS) has been produced by the Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI). This GTS defines the interfaces and Terminal Adaptation Functions
14、(TAF) integral to a Mobile Termination (MT) which enables the attachment of asynchronous terminals to a MT within the digital cellular telecommunications system (Phase ZPhase 2+). This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+ enhancements/features t
15、o the version 4 GSM technical specification. The European Telecommunications Standard from which this Phase 2+ GTS has evolved is Phase 2 GSM ETS 300 583 (GSM 07.01 version 4.5.1). GTS are produced by TC-SMG to enable the GSM Phase 2 + specifications to become publicly available, prior to submission
16、 for the formal ETSI standards approval procedure to become European Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+ specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile communications. The contents of
17、this GTS are subject to continuing work within TC-SMG and may change following formal TC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in version number as follows: Version 5.x.y where: y the
18、 third digit is incremented when editorial only changes have been incorporated in the specif ication; x the second digit is incremented for all other types of changes, .e. technical enhancements, corrections, updates, etc. NOTE: TC-SMG has produced documents which give the technical specifications f
19、or the implementation of the digital cellular telecommunications system. Historically, these documents have been identified as GSM Technical Specifications (GSM-TSs). These TSs may have subsequently become I-ETSs (Phase l), or ETSs/ETSI Technical Reports (ETRs) (Phase 2). TC-SMG has also produced ET
20、SI GSM TSs which give the technical specifications for the implementation of Phase 2+ enhancements of the digital cellular telecommunications system. These version 5.x.x GSM Technical Specifications may be referred to as GTSs. ETSI GSM*:07-02 96 H 3400855 0309860 b95 Page 6 GSM 07.02 Version 5.1 .O:

40、ccess Configuration This configuration is as shown in Figure 1 of GSM 04.02. This specification specifically refers to the Mobile Terminations (MTs) which support terminals of the type TE1 and TE2 with asynchronous capabilities. The TAF is functionally a part of an MT1, MT2 or MTO with an integral a
41、synchronous data capability. 2.2 Terminal Adaptation Function The TAF provides facilities to allow manual or automatic call control functions associated with alternate speechIdata, speech followed by data and circuit switched services. The following functions are also included: Conversion of electri
42、cal, mechanical, functional and procedural characteristics of the V series and ISDN type interfaces to those required by the PLMN Bit rate adaptation of the V series data signalling rates and the ISDN 64 kbit/s to that provided in the PLMN The mapping functions necessary to convert automatic calling

46、describes the rate adaptation scheme to be utilized over the Base Station (BS) to Mobile Station (MS) link. GSM 03.10 refers to the rate adaptation elements to be provided in the MS. 3.1.1 Rate Adaptation - V series This is provided as indicated in GSM 04.21 3.1.2 Rate Adaptation - S Interface (1.42
47、0) The ISDN rate adapted frame format is modified to the PLMN rate adapted format as indicated in GSM 04.21. 3.2 Interchange Circuit Signalling Mapping The interchange circuit signalling mapping at the interface between the TE2 and the MT shall conform to CCIlT V.24. The signals required at this int
48、erface are shown in Table 2. GSM 04.21 refers to the frame structure and identifies the use of the status bits for the carriage of signalling information. Status bits (S1 ,S3,S4,S6,S8,S9 and X): The bits S and X are used to convey channel control information associated with the data bits in the data
49、 transfer stage as shown below. The S bits are put into two groups SA and SB to carry the condition of two interchange circuits. The X bit is used to carry the condition of circuit 106. The mechanism for proper assignment of the control information from the transmitting signal rate adapter interface via these bits to the receiving signal rate adapter interface is shown below in table 1. For the S and X bits, a ZERO corresponds with the ON condition, a ONE with the OFF condition. Table 1 : General mapping scheme for V.21, V.22 and V.23 interchange circ
