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 s ettings 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") occu rs 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 hap pens because of short intermediate states of the

list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configura tion

displayed is always the current configuration at the time of the last d isplay.

The list of active calls displayed with this URC will always be terminated with an empty line preceded by pre fix

''^SLCC: '', in order to indicate the end of the list.
