Configuring ISDN Support

You can add one optional network interface module to the VSX 5000,

VSX 7000, VSX 7000s, VSX 7000e, and VSX 8000 systems. This lets you extend the functionality of the systems so that you can:

•Make ISDN calls over a BRI network.

•Make ISDN calls over a PRI/T1 network (in North America and Japan) or PRI/E1 (outside of North America and Japan) with the VSX 7000,

VSX 7000s, VSX 7000e, or VSX 8000.

•Connect encryption or other third-party network equipment using a Serial V.35/RS-449/RS-530 interface with the VSX 7000, VSX 7000s, VSX 7000e, or VSX 8000.

The VSX 3000 or VSX 3000A (ISDN model) includes a BRI network interface for ISDN calling.

The VSX 5000 with an optional BRI module supports ISDN calling.

This section describes the settings for all optional network interfaces and identifies the settings that are available for specific network interfaces.

You can configure a network interface option if the corresponding network interface module is installed. The system automatically detects the type of interface installed and displays only the required configuration screens.
