Setting Up Your System Hardware

Connecting Desktop Systems to the ISDN BRI Network

The VSX 3000 and VSX 3000A desktop systems are available with or without the built-in Quad BRI network interface. The setup sheet for the IP with ISDN system shows how to connect it to a BRI network.

If you purchased the VSX 3000 or VSX 3000A system with IP and ISDN, you will need:

NT-1 device, if the system will be connected to a network that provides a U interface

Up to 4 BRI lines that will not be shared with other equipment

If you connect fewer than four BRI ports on the system’s network interface module, connect them in ascending order, starting with port 1.

The diagram below shows a general view of how to connect the VSX 3000 or VSX 3000A system to the ISDN using the Quad BRI network interface.
