This section is applicable to all endpoints other than the UNIStim IP endpoints.
CS 1000 endpoint user experience
The user is typically unaware that the endpoint is connected to a Media Gateway Controller (MGC) registered to a server providing call processing. All services are carried out invisibly, except under:
System fault conditions such as network failures.
Maintenance or administration operations that take the endpoint off-line.
The MGC finds its controlling call server and registers itself. CS 1000 has the underlying software required to map messages to and from the units in the MGC correctly.
Device Adapter endpoint user experience
The MGC finds its controlling call server and registers itself. However, in this case the controlling server is the Device Adapter, which:
Maps each device on the MGC by a Terminal Number or TN (legacy Loop, Shelf, Card, and Unit) into information which can be used to retrieve the station identity.
Registers the device by its SIP identity with the Session Manager.
Acts as a configuration retrieval interface with Session Manager and Communication Manager.
Completes any other aspects of the registration of the endpoint.
Unlike the UNIStim endpoints, the non-IP endpoints historically have not needed to register individually. Doing so allows the endpoints the potential to accept new services and features provided by Communication Manager without reworking the architecture.
