Fax Clas - Motorola G24 Guide Developer's Manual

Fax Class 1
Facsimile machines were developed for sending digitized documents over the General Switched
Telephone Network (GSTN) These facsimile terminals are in widespread use around the world.
The operation of facsimile terminals has been standardized in Recommendations T.4, T.6 and
T.30. The cellular network also supports the facsimile service within the cellular network and also
with the GSTN network. The G24 is configured as an external "facsimile DCE", connected to the
terminal by a standard serial port (for example, Recommendation V.24), using serial data
interchange. The G24 supports Fax Class 1, with a few exceptions, marked as "Not supported" in
the table below. The SW flow control is mandatory (using the DC1/ DC3 characters). (ITU -
T.31section 5.3)
The following table shows the Fax Class 1 command summary.
