标准简介：This Recommendation is concerned with the procedures which are necessary for document
transmission between two facsimile terminals in the general switched telephone network.
These procedures essentially comprise the following:
– call establishment and call release;
– compatibility checking, status and control command;
– checking and supervision of line conditions;
– control functions and facsimile operator recall.
1.1.2 Only the procedures with their corresponding signals are specified in this Recommendation.
1.2 Classification of operating methods
1.2.1 This Recommendation regulates the operational sequence of manually operated facsimile
terminals as well as of automatic terminals.
The automatic facsimile terminal is understood to be a terminal which is capable of performing all
procedures (listed in 1.1) automatically. In this case, an operator is not necessary.
If, however, an operator is required for any of these procedures, the terminal must be regarded as a
manually operated terminal.
1.2.2 Based upon all combinations which may result from the fact that there are manually
operated terminals and automatic facsimile terminals, the operating methods shown in Table 1 are
possible.
