ISDN BRI Ports

The AN/DC and ANH-8/DC support the BRI standard for ISDN using an optional ISDN/BRI module. The integrated ISDN BRI functionality allows you to connect directly to the ISDN network, as opposed to connecting via 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.

Table C-6 lists the ISDN connector pinouts.
