ISDN BRI U Interface

The ARN supports the BRI standard for ISDN using an optional ISDN/BRI
adapter module. The integrated ISDN BRI functionality allows you to connect
directly to the ISDN network, through a U interface, as opposed to connecting
over a terminal adapter. This solution reduces equipment costs and simplifies
connection to an ISDN switch.
The BRI implementation supports two dial service applications: dial-on-demand
and dial backup. Configuring Dial Services describes these services and how to
configure them for connection to an ISDN network.
