3.4 Service Entities

The basic logical entities in the service model used to construct a service are:
•
•
•
Figure 1
3.4.1
The most basic required entity is the customer ID value which is assigned when the
customer account is created. To provision a service, a customer ID must be
associated with the service at the time of service creation.
3.4.2
Each subscriber service type is configured with at least one service access point
(SAP). A SAP identifies the interface point for a service on an Nokia ISAM router
(Figure 2). The SAP configuration requires that slot information be specified. The slot
parameters must be configured prior to provisioning a service (see the "Port
Features" section of the FD 100/320Gbps NT and FX NT IHub Interface Guide).
A SAP is a local entity to the ISAM and is uniquely identified by:
•
•
•
SAPs can only be created on ports designated as "access" or "hybrid" in the physical
port configuration. SAPs cannot be created on ports designated as core-facing
"network" ports as these ports have a different set of features enabled in software.
