Universal Mobile Telecommunications System (UMTS); Technical realization of facsimile Group 3 non-transparent (V12.0.0; 3GPP TS 23.146 version 12.0.0 Release 12)
"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 present 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 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 NOTE: V.25bis is outdated.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."
