scope:

This ETS specifies the upper layers of the communications protocol employed in the group 4 class 1 facsimile communication procedures, i.e. the session layer and above.

This ETS is based upon CCITT Recommendations:

T.503 "A document application profile for the interchange of group 4 facsimile documents" (the document application profile (DAP)) and

T.521 "Communication application profile BT0 for document bulk transfer based on the session service (according to the rules in T.62bis)" the communication application profile (CAP),

as derived from the T.400 series of recommendations (Document Architecture, Transfer and Manipulation) and other recommendations referred to therein.

This ETS is closely related to 5 other ETSs on group 4 class 1 facsimile:
