9.4.1 Additional notes on ^SCCFC, ^SCCWA, ^SCLCK
The output of ^SCCFC, ^SCCWA, ^SCLCK depends on the teleservices coded in <class>. If no tele-
service or bearer service is active for a given interrogation “7” is generated as default value for the
<class> parameter, with only line being displayed (see example 1 below). If a service is activated for
one or several classes, only the active classes will be displayed (see example 2).

The number of parameters displayed in the ^SCCFC and ^SCLCK output strings differs from the
equivalent +CCFC and +CLCK output strings: In contrast to the +CCFC string, ^SCCFC also includes
the <reason>. Likewise, the ^SCLCK string includes additionally <fac>.

Example 1
When you check the CFU status of all classes, while none is active the fol-
lowing responses will be displayed:
lowing responses will be displayed:
Using at+ccfc=0,2
+CCFC: 0,1
+CCFC: 0,1
+CCFC: 0,2
+CCFC: 0,4
OK
Using atd*#21#
^SCCFC: 0,0,7
^SCCFC: 0,0,7
OK
Example 2
To register and activate CFU for voice calls:
at+ccfc=0,3,0
at+ccfc=0,3,0
1771234567
OK
As an alternative you can use the ATD command:
atd**21*01771234567*11#
atd**21*01771234567*11#
^SCCFC: 0,1,1,"+491771234567",,145
OK
To check the status of all CFU settings using ATD (only active class will be
displayed):
atd*#21#
displayed):
atd*#21#
^SCCFC: 0,1,1,"+49
1771234567",145
OK
To check the status of all CFU settings using AT+CCFC (all classes will be
displayed)
at+ccfc=0,2
displayed)
at+ccfc=0,2
+CCFC: 1,1,"+49
1771234567",145
+CCFC: 0,2
+CCFC: 0,4
OK
Example 3
To query the status of CFU for voice calls:
atd*#21**11#;
^SCCFC: 0,1,1,"+491771234567",145
OK
atd*#21**11#;
^SCCFC: 0,1,1,"+491771234567",145
OK
Example 4
To query the status of CFU for voice + SMS + data:
atd*#21**10#;
atd*#21**10#;
