The present document defines the
22、 interfaces and Terminal Adaptation Functions (TAF) integral to a Mobile Termination (MT) which enables the attachment of synchronous terminals to a MT within the 3GPP system. The contents of the present document are subject to continuing work within the TSG and may change following formal TSG appro
23、val. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 o
24、r greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 12
25、7 003 V13.0.0 (2016-01)53GPP TS 27.003 version 13.0.0 Release 131 Scope The present document defines Terminal Adaptation Functions (TAF) which are integrated in a Mobile Termination (MT) and which enable the use of synchronous bearer services in the PLMN and the attachment of Synchronous synchronous
26、 Terminals terminals to an MT (see 3GPP TS 24.002 3). For the case where asynchronous terminals are attached to the TAF when using synchronous bearer services in the PLMN, the reader is referred to 3GPP TS 27.002 36 for the asynchronous MT-TAF interface specifics and to the present document for sync
27、hronous bearer service specifics on the TAF-IWF interface. The general aspects of Terminal Adaptation Functions are contained in specification 3GPP TS 27.001 9. The present document covers support of synchronous data services (see 3GPP TS 22.002 6) for the following interfaces and procedures: - V.22
28、 15 DTE/DCE Interface; - V.22 bis 16 DTE/DCE Interface; - V.26 ter 19 DTE/DCE Interface; - X.21 bis 24 DTE/DCE Interface; - X.32 30 Procedure; - V.25 bis 18 Procedure; NOTE: From R99 onwards the support of the following services are no longer required by a PLMN: - the dual Bearer Services “alternate
29、 speech/data“ and “speech followed by data“; - the dedicated services for PAD and Packet access; - BS 21 . 26 and BS 31 . 34. From REL-4 onwards the support of the following service is no longer required by a PLMN: - the synchronous Bearer Service non-transparent (BS 30 NT). the Teleservice Facsimil
30、e non-transparent (TS 61/62 NT) for A/Gb mode. The support of these services is still optional. The specification of these services is not within the scope of the present document. For that, the reader is referred to GSM R98 or R99 respectively. NOTE: Please note that the Gb interface does not play
31、any role in the scope of the present document although the term A/Gb mode is used. GERAN Iu mode is for further study. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identif
