^SLCC:
URC "
^SLCC
" displays the list of current calls as displayed with the execute command
AT^SLCC
. The list is dis-
played in the state it has at the time of display, not in the state it had when the signal was generated.
The URC's occurrence indicates call status changes for any of the calls in the list of current calls.
Please refer to
Call Status Information
and
AT^SCFG
for further information about the configuration of
this URC.
Event reporting can be enabled separately for each interface. Interface settings are saved with
AT&W
and can be
displayed with
AT&V
. Additionally, The URC presentation mode for the interface must be configured with
AT+CMER
.
Depending on the value of
AT^SCFG
setting , Indicator "
^SLCC
" will be issued (if configured with write
command
AT^SLCC
and
AT+CMER
)
• when a state transition ends in state "active" or in state "unknown" (if
AT^SCFG
setting ="restricted")
• when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of
active calls, or when a traffic channel is established (if
AT^SCFG
setting ="verbose").
If multiple displays of identical list configurations occur, this happens because of short intermediate states of the
list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configuration
displayed is always the current configuration at the time of the last display.
The list of active calls displayed with this URC will always be terminated with an empty line preceded by prefix
''^SLCC: '', in order to indicate the end of the list.
Command Description

information response is sent to TE.
Use the write command to activate or deactivate event reporting for URC "
^SLCC
". Event reporting can be
enabled separately for each interface. Interface settings are saved with
AT&W
and can be displayed with
AT&V
.
