Test Branch 8

Overview

The Test branch of the Top-Level menu allows you to initiate various modem tests. Use these tests if you are having data communication problems, such as periodic character loss, random errors, or constant format errors. By the process of elimination, you can usually isolate the fault in your system.

There are six selections under Test: Abort, Self (Self-Test), Loc Analog Loop (Local Analog Loopback), Rem Digital Loop (Remote Digital Loopback), Loc Digital Loop (Local Digital Loopback), and Pattern. The only tests that can operate concurrently on a single modem are Pattern with a Local Analog Loopback and Pattern with a Remote Digital Loopback. If any test is operating, besides the two combinations just mentioned, it must be canceled before starting another test.

The Test branch only initiates and cancels tests. If any parameters need to be set, refer to Test in Chapter 5, DCP Configuration.
