CUsing the LoopTest Utility C

Overview

The LoopTest utility enables you to check your ISDN line quickly and easily. It checks for electrical problems, hardware connectivity, and ISDN compatibility problems.

LoopTest also tests the adapter’s ISDN line by establishing 2 ISDN B channels in a loopback connection. One channel is set up to accept incoming calls, and the other channel calls the first channel. When the connection is established, the calling channel sends data, which is checked when it gets to the receiving channel. At the end of the test, LoopTest stops the communication. If an error occurs during testing, LoopTest displays a warning and stops the communication at that point.

This appendix explains how to perform various LoopTest tasks, including:
