Self
Self performs an internal self-test of the modem, which takes less than a minute to complete.
The modem must be offline; otherwise, Invalid Command appears.
To access Self from the Test branch, make the following selection:
Select Self. (All LCD cells and DCP status indicators light.)
If the modem passes the self-test, Pass appears on the LCD. If it fails, Failed appears. If the
modem fails, contact your service representative. If Invalid Command appears on the LCD, the
modem is operating on dial lines or another test is in progress. If another test is in progress,
select Abort to clear the current test and try again. If the modem is operating on dial lines,
disconnect to clear the dial lines, and then choose Self. If the modem receives a ring signal
during this test, the test is canceled and the RI Abort message appears.
To exit this function and remain in the Test branch, press the
Top-Level menu, press the

minutes). If the remote self-test fails, there will be a Device
Failure alarm message when the remote modem's Device
Health and Status (DeviceHS) branch is accessed.
