Technical realization of facsimile Group 3 non-transparent
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NOTE: V.25bis is outdated.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.
