Test Branch

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 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 the

Test

section in

Chapter 8, Configure Branch.
