Tlk/Data; Test Branch - Paradyne COMSPHERE 3920PLUS Technical Reference Manual

Test Branch

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 parameters need to be set, refer to the
Multiport Mode
