Selecting number “4” from the BERT menu will display
the first of the
BERT Test Functions, the Time-out
Screen
(Figure 22). The time out can run for a specific
duration by entering the hours and/or minutes, or can
run indefinitely by entering 00:00, per the note on the
screen. With no test running, selection “
5” from the
BERT menu will allow the tester to toggle the test signal
in the opposite direction (from customer to network and
vice versa).
When “
1” is pressed to start the test, option “5” changes
to “
Inject Bit Errors” as in Figure 23. This allows the
tester to generate errors from this test origination point
to validate the test results.
