25、rship Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. 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 incre
26、ase 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 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancement
27、s, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. ETSI ETSI TS 127 002 V13.0.0 (2016-01)63GPP TS 27.002 version 13.0.0 Release 131 Scope The present document defines the interfaces and Terminal Adaptation Functions (TAF
28、) integral to a Mobile Termination (MT) which enable the use of asynchronous bearer services in the PLMN and the attachment of asynchronous terminals to a MT (see 3GPP TS 24.002 3 and 3GPP TS 23.101 6). The general aspects of Terminal Adaptation Functions are contained in 3GPP TS 27.001 10. The pres
29、ent document covers support of these services for the following interfaces and procedures: (i) ITU-T V.14 16 procedures. (ii) ITU-T V.21 17 DTE/DCE interface. (iii) ITU-T V.22bis 18 DTE/DCE interface. (iv) ITU-T V.32 24 DTE/DCE procedures. (v) ITU-T I.420 14 S interface. (vi) ITU-T V.250 22 signalli
30、ng procedures. The asynchronous data rates between the MT and the IWF are defined in 3GPP TS 22.002 5. NOTE: From GSM R99 onwards the following services are no longer required in a PLMN: - the dual Bearer Services “alternate speech/data“ and “speech followed by data“; - the dedicated services for PA
31、D and Packet access; - the BS 21 . 26 and BS 31 . 34. 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 Release 98. NOTE: Please note that the Gb interface does not play any ro
32、le in the scope of the present document although the term A/Gb mode is used. GERAN Iu mode is for further study. 1.1 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
