29、le service, as basically defined in CCITT Recommendation F. 160, is an international telematic service for IS0 A4 document transmission between two facsimile stations. The service specification is comprised of two parts: the control protocol described in CCITT Recommendation T.30, and the document t

30、ransmission coding described in CCITT Recommendation T.4. The GSM facsimile Teeservice is intended to allow facsimile connections between group 3 apparatus using: . - - a GSM PLMN as a stand alone facility, for mobile to mobile communication; a GSM PLMN to gain access to fixed networks PSTN and ISDN

31、, for mobile to/from land communication. For this .Teleservice, the document coding is as CCITT Recommendation T.4 with no modifications. The protocol used is CCIlT Recommendation T.30 modified within the PLMN as detailed in this Specification. The interworking between different networks is based on

32、 CCIlT Recommendation X.300. The particular features of this Teleservice are: - it uses point-point communication; - the information transfer capability is dual “Speech“/“Group 3 Facsimile“ for Teleservice 61 and “Group 3 Facsimile“ only for Teleservice 62; - both mobile originated and terminated ca

33、lls are supported; - the information transfer mode is circuit, duplex, synchronous and symmetric; - different end-to-end transfer rates are used within the same call to take advantage of the better radio path error rate; - use of a cfandard synchronous terminal adaptation function (as per TS GSM 07.

34、03) within the MS. 2 NETWORK ARCHITECTURE The network architecture applicable to this Teleservice is shown in Fig 1/03.45, below. Fig. 1/03.45 Network architecture This shows the case of mobile to fixed network interworking. For mobile to mobile calls, there would effectively be a loop back within t

I I I I # FAX 2w I I I I Fig. 2/03.45 Reference configurations The Teleservice definition

36、 in TS GSM 02.03 regards the group 3 facsimile terminal as a 2-wire analogue terminated equipment, In order to connect this to the MT2 a separate “Fax Adaptor“ device is necessary. This configuration, shown in Fig.2a/03.45, has to be considered as the standard configuration, so that all the existing

37、 Group 3 facsimile apparatus can be connected to the PLMN. An alternative realisation would be to combine a standard group 3 facsimile machine and the Fax Adaptor into a specially developed “GSM facsimile machine“ , directly providing a digital output. Although such a device must appear to the MT2 a

38、s identical to the Fax Adaptor he. with an identical interface and protocol), it would allow for a significantly smaller and simpler facsimile machine. This configuration is shown in Fig.2d/03.45 and is regarded as a desirable alternative. In addition of course, it is always possible to realise an M

39、TO, as per Fig.2f/03.45, where both the facsimile and mobile termination functions are considered to be part of one integrated unit. The remaining configurations concern the use of an S interface and are considered as optional configurations. Their use is for further study. The particular terminal a

40、daptation functions used are those detailed in TS GCM 07.03 and the interface to the MT2 used is synchronous V.24 with an option for support of V.25bis procedures for autocaliing and autoanswering. - _ -_ - _ - H 3404583 0116807 598 Page 11 GSM 03.45 version 4.4.0 3.1 Fax Adaptor functionality The F

COMPOSE MODEM I TONE HANDLING Fig.3/03.45 Fax Adaptor scheme Whether it has to be a function internal to the GSM PLMN, or an external accessory as

42、sociated with the Group 3 apparatus, is beyond the scope of this Specification, and in any case, does not affect at all the working of the procedure as here described. It can be functionally partitioned in two sections: - an analogue section, dealing with: - the modulation and demodulation processes

43、 according to CCITT Recommendation V.21, V.27ter and V.29 as explained in T.4 and T.30; - handling of the signalling on the 2-wire path to the facsimile machine, including autocalling and autoanswer functions where necessary (see section 61. - a digital section, dealing with: - monitoring and where

44、necessary, manipulation of the T.30 protocol as detailed in the rest of this Specification; - overall control of the adaptor; - connection over the synchronous V.24 interface to the MT as described in TC GSM 07.03; - where necessary, autocalling and autoanswering functions according to V.25bis. In t

45、he following this specification will reference the Fax Adaptor functionality, considering the most general case where it operates as a full-featured (see Fig.3/03.45) separate block (see Fig.2a/03.45), as this reference configuration is implicitly or explicitly exhaustive of all service related tech

46、nical aspects. 3.2 GSM Facsimile Machine functionality The special GSM facsimile machine shown in the MS configuration of Fig.2d/03.45 has a similar functionality to the digital part of the Fax Adaptor, but without any of the analogue portions.
