Configuring ISG Support for Prepaid Billing
How to Configure ISG Support for Prepaid Billing

The quota-depleted event is not necessarily an indication that a subscriber does not have any more credit.
ISG does not know for certain whether the subscriber has any more credit until a reauthorization
response is returned from the billing server. For this reason, some service providers may choose to
forward subscriber packets upon quota depletion until a reauthorization response is returned.
The default ISG behavior is to drop subscriber packets when a quota-depleted event occurs.
Prerequisites
If you specify a named control class map, this task assumes that the class map has been configured. See
