27、Scope The present document describes the procedures allowing the technical realization of the real time end-to-end facsimile group 3 service within the UMTS PLMN using non-transparent network support according to the definition of the Teleservices 61 and 62 specified in 3GPP TS 22.003. Within the pr
28、esent document particular attention is given to Teleservice “Alternate speech/facsimile group 3“ (Teleservice 61). However, the definitions apply also to Teleservice “Automatic facsimile group 3“ (Teleservice 62) with the exception of all actions concerned with the speech phase. Consequently, in the
29、 following descriptions the term “Teleservice“ denotes both Teleservice 61 and Teleservice 62 as appropriate. NOTE: V.25bis is outdated. References to V.25bis procedures need to be replaced by corresponding procedures based on V.250 and 3GPP TS 27.007. 2 References The following documents contain pr

47、n The fixed network facsimile group 3 service is an international telematic service for document transmission between two facsimile group 3 terminals. The service specifications are comprised of two parts: - the control procedures described in ITU-T Recommendation T.30; - the document transmission c
48、oding described in ITU-T Recommendation T.4. The UMTS facsimile group 3 Teleservice allows connections between facsimile group 3 terminals using: - a UMTS PLMN as stand-alone facility for mobile-to-mobile communication; - a UMTS PLMN to have access to fixed networks PSTN and/or ISDN for mobile to/fr
49、om fixed network communication. For this Teleservice, the coding of the facsimile document is as per ITU-T Recommendation T.4 and the protocol as per ITU-T Recommendation T.30 both modified within the PLMN as detailed in the present document. The interworking between different networks is based on ITU-T Recommendation X.300. The particular features of this Teleservice are: - it uses point-to-point communication; - the information transfer mode is circuit, duplex, asynchronous; - the information transfer capability is
