Connecting the VSX 3000 Desktop System to the ISDN BRI Network

2 - 12
The VSX 3000 desktop system is available with or without the built-in Quad
BRI network interface. The setup sheet for the VSX 3000 IP with ISDN system
shows how to connect it to a BRI network.
If you purchased the VSX 3000 IP with ISDN system, 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
system to the ISDN using the Quad BRI network interface.
