Supplementary Service Call Barring:

Supplementary Service "Call Barring" allows to specify conditions under which calls will be disallowed by the network.

The availability of the Supplementary Services varies with the network. To benefit from call barring the client will need to subscribe them, though a limited number of call barring types may be included in the basic tariff pack- age.

When you attempt to set a <facility> or <class> which is not provisioned, not yet subscribed to, or not sup- ported by the module, the setting will not take effect regardless of the response returned. The responses in these cases vary with the network (for example "OK", "+CME ERROR: Operation not allowed", "+CME ERROR: Oper- ation not supported" etc.). To make sure check the extended error response with AT+CEER and the lock status with <mode>=2.

<password>: Network password supplied from the provider or operator. Usually there is one password which applies to all call barring options. For details contact your provider.

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".
