Value Acquisition for Single Subscriptions

When a subscriber has a single subscription to a service, the SAE ranks sources in the following order when it selects values for parameters:

1. The service sessions associated with the subscriber
2. The subscriber’s subscription to a service and then the subscriber
3. Each parent subscriber’s subscription and then the parent subscriber
4. The services in order of the precedences defined for their associated service scopes
5. The default values for the local parameters in the policy group
6. Fixed settings of all global parameters defined in the policy repository
7. The service scopes, in order of precedence for each of the services. See:
8. Values for system parameters that are available only when the SAE starts managing the interface (for example, actual bandwidth rates)
9. The default values for global parameters defined in the policy repository

Figure 17 illustrates how the SAE selects values for a subscriber with one subscription to a service.
