Endpoint applications with signaling
An endpoint application is the origination or destination point of a wideband call. Endpoint applications
can be any number of data applications based on the customer's particular needs.
ISDN-PRI terminal adapters
For wideband switching with non-ISDN-PRI equipment, you can use an ISDN-PRI terminal adapter.
ISDN-PRI terminal adapters translate standard ISDN signaling into a form that can be used by the
endpoint application and vice versa. The terminal adapter also must adhere to the PRI-endpoint
boundaries as administered on Avaya Communication Manager when handling both incoming (to the
endpoint) applications and outgoing calls.
The terminal adapter passes calls to and receives calls from the line-side ISDN-SETUP messages
indicating the data rate and specific B-channels (DS0) to be used and communicates all other call status
information via standard ISDN messages. See DEFINITY Line-Side ISDN Primary Rate Interface
Technical Reference for more information.
