This chapter describes the diagnostic tests, provides
user assurance test procedures, and troubleshooting ·
guidelines to use if you encounter a problem while
setting up or using the modem.
Diagnostic Tests
When you turn the power on, the modem
automatically runs a series of self-diagnostic tests.
You can view the results of these tests by using the 11
command. This command returns a decimal number
that represents the sum of the failure codes triggered
during testing. If no errors are detected during the
diagnostic tests, the DTE screen displays 000 (zero).
You can run the diagnostic tests at any time by using
the &T9 command. However, do not run the
diagnostic tests during a current communications
session; this disconnects the line and resets the
modem. The &T9 command displays the results of
the tests as a short message on the screen. If no errors
are detected, the &T9 command returns a
Diagnostics Complete message.
