Troubleshooting and
Diagnostics
This chapter describes how to perform diagnostics tests on ASMi-31.
The function of diagnostic tests on ASMi-31 is to:
•
Check that the system is operating normally
•
Isolate faulty equipment or cables
•
Identify other sources of system malfunction.
Tests are activated via the corresponding DTE pins and monitored via the
ASMi-31 front-panel LED indicators.
4.1 Diagnostic Tests
The diagnostic capabilities of the ASMi-31 modem allow rapid checkout of
the DTEs, the ASMi-31 modem, and connecting lines. The test will
immediately verify the operational performance of each unit in the system
or provide an indication of equipment failure.
Before testing the operation of the data system equipment and 2-wire line
circuits, first ensure that all units are powered on and configured normally,
then perform the test steps described below, in order.
ASMi-31 supports two types of loopback tests for evaluating the operation of
the data system equipment and line circuits. Using these loopbacks, you can
test the communication between the attached equipment, internal circuitry
of the local ASMi-31 and the remote ASMi-31.
