7.23 AT^SLCC Siemens defined command to list the current calls of

the ME

Command ^SLCC covers essentially the same information as GSM 07.07 command AT+CLCC, with the following

additions:

• 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.
