For example, the default setting 7 represents the
sum of the integers 1, 2 and 4 (voice, data and fax).
The value 255 covers all classes.
If parameter "class" is omitted, the default value 7
is used.
Notes
• The AT+CLCK command offers the full range of
parameters according to the GSM specifications. However, when
you attempt to use a service option which is not provisioned or not
yet subscribed to, the setting will not take effect regardless of the
response returned.
The responses in these cases vary with the network (for example
"OK", "Operation not allowed", "Operation not supported" etc.). To
make sure check the extended error response with AT+CEER and the
lock status with =2.
• The command has been implemented with the full set of
parameters according to GSM 07.07. For actual applicability of a
desired Call barring service to a specific service or service group (a
specific value) please consumable A.1 of GSM 02.04.
• If an outgoing Fax or Data Call is rejected due to an active "call
barring" supplementary service, the call will be terminated with
result code NO CARRIER.
Under the same conditions, an outgoing Voice call will be
terminated with result code NO DIALTONE.
