Password string used to lock and to unlock a

<facility>. Length and authority for passwords depend on the

<facility> in question and are therefore listed in the section on parameter <facility>. Passwords can be

modified with

AT+CPWD or AT^SPWD.

Integer or sum of integers each representing a class of information, i.e. a bearer service, telecommunication ser-

vice or bearer service group as defined in "GSM 02.04".

1voice

2 class 2 ("data") comprises all those individual data classes between 16 and

128, that are supported both by the network and the MS. This means, a setting

made for class 2 applies to all individual data classes (if supported). In addition,

you can assign a different setting to a specific class. For example, you can acti-

vate Call Forwarding for all data classes, but deactivate it for data class 64,

"dedicated packet access".

4fax

8SMS

16 data circuit sync

32 data circuit async

64 dedicated packet access

128 dedicated PAD access

1...[7]...255 combination of some of the above classes.

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 <class> 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 set-

ting 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

<mode>=2.

• The command has been implemented with the full set of

<class> parameters according to GSM 07.07. For

actual applicability of a desired Call barring service to a specific service or service group (a specific

<class>

value) please consult table 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.
