12. FAX Commands
This chapter describes the AT commands used for fax communications.
If the ME is acting as a fax modem for a PC based fax application (e.g. "WinFax") it is necessary to select the
proper Service Class (Fax Class) provided by the ME. The ME reports its Service Class capabilities, i.e. the current
setting and the range of services available. This is provided by the AT+FCLASS command.
Service Classes supported by the ME:
AT+FCLASS Parameter Service class Reference, Standard
0 Data modem e.g. TIA/EIA-602 or ITU V.250
1 Service Class 1 EIA/TIA-578-A
During an active fax connection the AT parser functionality on the used channel is limited to the AT commands
which according to the ITU V.250 and T.31 specifications are mandatory for fax communications. The functions
of these AT commands are usually supported by commonly used fax applications.
12.1 FAX parameters
This section describes the parameter used by some of the fax-specific AT commands. To find out the
value(s) actually supported by the parameter use the test commands either in on-hook or off-hook mode.
Parameter Description
(num)
Modulation scheme
3 V21 Ch2 - 300 bps
24 V.27ter - 2400 bps
48 V.27ter - 4800 bps
72 V.29 - 7200 bps
96 V.29 - 9600 bps
Note
• For AT+FRH and AT+FTH, parameter can take value 3 only, while AT+FRM and AT+FTM never support
=3.

Result Code

Meaning
This facsimile error message notifies the DTE that the DCE has
received a different signal (tone or carrier) than expected. This
allows the DTE to recover by requesting the DCE to look for an
alternative tone or carrier signal.
