D.4 Call Mode +CMOD
D.4.1 DESCRIPTION
Set command selects the call mode of further dialing commands (
D
) or for next answering command (
A
). Mode can be
either single or alternating (in the present document, terms "alternating mode" and "alternating call" refer to all
GSM/UMTS bearer and teleservices that incorporate more than one basic service (voice, data, fax) within one call). When
single mode is selected the call originating and hang-up procedures are similar to procedures specified in ITU-T
Recommendations V.25ter [14], T.31 [11] and T.32 [12]. In GSM/UMTS there can be voice followed by data (refer 3GPP
TS 22.002 [1]), alternating voice/data (refer 3GPP TS 22.002 [1]) and alternating voice/fax calls (refer 3GPP TS 22.003
[2]). Refer next two subclauses for alternating call control methods. Test command returns values supported as a
compound value.
NOTE:
+CMOD
shall be set to zero after a successfully completed alternating mode call. It shall be set to zero also after a
failed answering. The power-up, factory (
&F
) and user resets (
Z
) shall also set the value to zero. This reduces the possibility
that alternating mode calls are originated or answered accidentally.
