Endpoint applications
An endpoint application is the origination or destination of a wideband call. Endpoint application 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.
Line-side (T1 or E1) ISDN-PRI facility
A line-side ISDN-PRI (T1 or E1) facility is comprised of a group of DS0s (24 for a T1 facility and 32 for
an E1 facility). In this context, these DS0s are also called channels. T1 facilities have 23 B-channels and
a single D-channel. E1 facilities have 30 B-channels, 1 D-channel, and a framing channel. Data flows
bi-directionally across the facility between the server and the ISDN-PRI terminal adapter.
