Digicom 3910, 3911 operation manual Self

Test Branch

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:

Test:		>
Abort		Self
F1	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.
