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.
WARNING
When this test is run in Remote mode, it will cause the Remote
mode session to be lost. The Remote mode session can be
reestablished after the self-test is complete (usually one or two
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.
To access Self from the Test branch, make the following selection:
F1
Test:
>
Abort
Self
F2
F3
Select Self. (All LCD cells and DCP status indicators light.)
NOTE
For tributary modems only, the test is delayed 30 seconds to allow
any outstanding network management messages to propagate
upstream before the VF channel is interrupted by the test.
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
key. To exit and return to the
Top-Level menu, press the
key.
