12.6 AT+FCLASS Fax: Select, read or test service class
AT+FCLASS sets the ME to a particular mode of operation (data, fax). This allows the ME to process information
in a manner suitable for that type of information.
Syntax
Parameter Description
0(&F) Data (e.g. EIA/TIA-602 or ITU V.250)
1 Fax class 1 (EIA/TIA-578-A, Service Class 1)
2 Fax class 2 (EIA/TIA SP-2388, an early draft version of EIA/TIA-592-A - Ser-
vice class 2.1)
Notes
• Using Error Correcting Mode (ECM) when sending FAXes over GSM should be avoided.
• If <n> is set to 1 or 2, all incoming calls will be answered as fax calls when ATA is issued on multiplexer chan-
nel 1 resp. ASC0. For calls explicitly signaled as voice or data calls, this procedure will fail with result code
"NO CARRIER", but the incoming call will continue to ring.
It is possible to change the setting of <n> to 0 while the call is ringing, and accept the call afterwards with ATA.
