Parameter Description

<n>(num)(&W)(&V)

[0](&F)	Data (e.g. EIA/TIA-602 or ITU V.250)
1	Fax class 1 (EIA/TIA-578-A, Service Class 1)

Notes

•Using Error Correcting Mode (ECM) when sending FAXes over GSM should be avoided.

•If <n> is set to 1, all incoming calls will be answered as fax calls when ATA is issued on multiplexer channel 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.
