When you run these tests, the system displays only that the test completed
successfully or failed. You can get additional problem isolation information by
running more than one test. For example, if the communications cable test is
failing, before you can isolate positively the cable as the cause of the problem, you
must also run the communications I/O adapter card test. If the communications
I/O adapter card test completes successfully, the communications cable is failing. If
the communications I/O adapter card test fails, the communications I/O adapter
card is failing.
Remote modem test: The remote modem test verifies that the remote modem is
operating correctly. For this test the remote modem must be compatible with
LPDA-1 or LPDA-2 diagnostic tests and must be attached via a nonswitched
telephone line. The MODEM parameter in the line description determines the
diagnostic test to run. Because this test loads a diagnostic program into the card,
you must vary off all lines from the communications I/O adapter before running
the test. The diagnostic program takes the place of the programs that are used for
normal operation.
If this test completes successfully, the remote modem and the telephone line are
operating correctly.
If this test fails, the remote modem or the telephone line is the cause of the
problem.
Local modem test: The local modem test verifies that the local modem is
operating correctly. For this test the local modem must be compatible with
LPDA-1, LPDA-2, or V.54 loop 3 diagnostic tests, or support the IBM ability to
wrap. The MODEM parameter in the line description determines the diagnostic
test to run. Because this test loads a diagnostic program into the card, you must
vary off all lines from the communications I/O adapter before running the test.
The diagnostic program takes the place of the programs that are used for normal
operation.
If this test completes successfully, the local modem, the communications cable, and
the communications I/O adapter card are operating correctly. However, modems
that are not compatible with LPDA-1 or LPDA-2 diagnostic tests are not
completely tested. It is possible that they are failing, although the local modem test
completes successfully.
If this test fails, the cause of the problem is the local modem, the communications
I/O adapter card, or the communications cable.
To further isolate the cause of the problem, run the communications cable test and
the communications I/O adapter card test.
Communications cable test: The communications cable test verifies that the
communications cable is operating correctly. Because this test loads a diagnostic
program into the card, you must vary off all lines from the communications I/O
adapter before running the test.
