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.
