Setting CbC limits
PRI pool limits for Call by Call services allows you to configure limits for service types without
interacting with the CO. This feature sets the minimum and maximum number of incoming and
outgoing calls per service type for the PRI pool. The following information applies to a NA PRI.

The number of active calls are tracked. Whenever a call is setting up, a check determines if the call
is allowed. Calls are not allowed if they exceed the maximum value for that service type or if they
use lines needed to maintain the minimum value of other service types.

1
Click on the keys beside Services, Telephony Services, General settings, and CbC limits
2
Click on the key beside a pool type (PRI-A to PRI-F).
