7.21 AT^SLCC Siemens defined command to list current calls of ME
AT^SLCC covers essentially the same information as GSM 07.07 command AT+CLCC, with the following addi-
tions:
• The execute command response contains an additional parameter <traffic channel assigned> indi-
cating whether the call has been assigned a traffic channel by the network (transmission of data or inband
information is possible).
• The additional write command allows to activate Event reporting for the list of current calls. If event reporting
is active for an interface, a call status transition (cf. Call Status Information) and (if desired) the
assignment of a traffic channel will generate an event report indication to this interface. In order to receive
this event report as an URC, the URC presentation mode for this interface has to be configured with
AT+CMER.
The frequency of event report generation can be configured with AT command AT^SCFG. Refer to Call
Status Information for further detail on the configuration options.
• The additional read command allows to determine the event reporting mode <n> which indicates whether the
interface receives event report indications for the list of current calls. Mind that the URC will be displayed only
if the URC presentation mode for the interface concerned has been configured with AT+CMER.
