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.

lists the ISDN connector pinouts.
Local Console Connections
The AN/DC and ANH-8/DC front panel contains one service interface, labeled
Console; its DB-9 plug connector provides an RS-232-D serial connection. You
use this local console port to connect
• Any VT100-compatible console device for direct console access
• Any Hayes-compatible modem for remote dial-in access
