Unsolicited Call Status information

if the list of current calls is empty:

^SLCC:

if one or more calls are currently in the list:

^SLCC: <idx>, <dir>, <stat>, <mode>, <mpty>, <traffic channel assigned>[,

<number>, <type>[, <alpha>]]

[^SLCC: <idx>, <dir>, <stat>, <mode>, <mpty>, <traffic channel assigned>[,

<number>, <type>[, <alpha>]]]

[... ]

^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 <sucs>, 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 <sucs>="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 <sucs>="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

The read command returns an indication whether event reporting is active for the current interface.

The exec command returns a list of current calls of ME. If command is successful, but no calls are available, no

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.
