Usage
Once the IMSI of an incoming call is known and matched with a specific operator policy, according to the
filter definition of the
filter definition of the
command, then that specific operator policy is selected to determine how the
incoming call is handled.
By default, all attaches are allowed. If no access limitations are needed, then do not use the

command.
Important:
Before using this command, ensure that the appropriate LAC information has been defined with the
command.
Use this command to define this operator policy‘s attach configuration.
Use this command to fine-tune the attach configuration specifying which calls/subscribers can attach and
which calls are restricted from attaching.
Attachment restrictions can be based on any one or combination of the options, such as location area code or

For calls under this operator policy, the following command restricts the attaches of all subscribers using the GPRS
access type.
Use the next command to reverse the previous attach restrict command:
Or, change the attach restriction to only restrict attaches of GPRS subscribers from specified LACs included in location
area list #2 and include failure-code 45 as the reject cause. This configuration requires two CLI commands:

In the case of a dual-access SGSN, it is possible to also add a second definition to restrict attaches of UMTS subscribers
within the LACs included in location area list #3.

Change the configuration to allow attaches for GPRS access for all previously restricted LACs - note that GPRS
attaches would still be limited.
