This parameter defaults to 7, equal to all classes, but the A3LA-RM only supports
Voice Call Barring so this is illegal. Therefore in practice the DTE must supply
<classx>=1 when querying or changing the status of any Call Barring facility. When
querying (<mode>=2), <passwd> is irrelevant and should be supplied as ”” in order
to allow the <classx>=1 parameter to be supplied.
For facilities “CS”, “SC”and “FD”, the <passwd> and <classx> parameters are not
relevant and will be ignored if supplied.
Test Command:
+CLCK=?
Test command returns the facility values supported by the phone. The response is in
the form:
+CLCK:(list of supported <fac>s)
Note:
Only “CS” will appear as a supported value if there is no SIM card in the
device.
Note:
+CLCK is closely related to +CPIN and +CPWD. See these commands for
additional information.
