Overview of Subscriptions
A subscription is an object in the directory that represents an enrollment to a service. Each subscription provides access to a particular service for that subscriber. A subscriber can have multiple subscriptions to a service. Table 7 shows the type of subscriptions you can configure for each type of subscriber.
If the service provider uses the SRC directory to hold all their subscriber data, residential subscribers must subscribe to primary services—such as Broadband Remote Access Server (B-RAS) through Point-to-Point protocol (PPP) or B-RAS through Dynamic Host Configuration Protocol (DHCP)—before subscribing to a value-added service.
Enterprise subscribers must subscribe to an access service (that is, a leased line), either directly or in a site or subscriber folder that is subordinate to the enterprise Without an access subscription, a service session cannot run in the network.
Retailers can subscribe to outsourced services if a service provider sources the access out through tunneling (Layer 2 Tunneling Protocol [L2TP] or PPP Terminated Aggregation [PTA]).
