This menu function is very useful for testing end-to-end
integrity of the network. First loop up the far end ESU LT.
Then send a 511 pattern from the local ESU LT. The
ERRORS
screen can then be used to determine if the link is
functioning properly by verifying that no errors are being
counted.
When running a 511 or QRSS pattern test, press E
insert an error into the pattern.
This menu selection is used to execute an internal self-test.
This is the same self-test that is performed automatically at
power up. The results of the self-tests are displayed in the
LCD. Upon invoking the command, the LCD displays
INITIALIZING
and test failures are displayed in the LCD
window (see Figure 7-6). The following board-level tests are
performed during self-test.
Test
Executing self-test disrupts normal data flow and prevents remote
communication until the self-test is completed (approximately 15
seconds).
