BERT Pattern Specifies the pattern to be transmitted during a test for the selected port.
Values: Marks, QRSS, 511, 2047, 2
15
, Spaces
Default: QRSS
NOTICE: The 2
15
pattern is the ITU (European) version, not the ANSI version.
Test Duration Specifies the length of time for which the test should run for the selected port.
Values: 15 minutes, 30 minutes, 1 hour, 24 hours, Continuous
Default: 15 minutes
You can also view the following read-only parameters from this screen:
Pattern Sync Displays the state of pattern sync during a test. If no test is in progress, “No
Test” is displayed. If a test is active, but the receiver is not in pattern sync,
“No Sync” is displayed. If the receiver is in pattern sync, “In Sync” is
displayed.
Elapsed Time Displays the time elapsed since a timed test began or, if completed, the total
test time.
Bit Errors Displays the total number of bit errors detected since the test began or since
error statistics were cleared.
Errored Seconds Displays the number of asynchronous errored seconds that have been detected
since the test began or since error statistics were last cleared.
%EFS Displays the percentage of time the test ran error-free. This ratio is derived
from the number of error free seconds divided by the number of seconds
accumulated in Elapsed Time.
Loop Table on Serial Interface Test Details Screen
The Loop table lets you specify the type of Loop test to be performed. The
types of tests available for you to choose from depend on the currently
selected interface. Loopback diagrams are shown in Appendix A, Figure A.1.
Values: No Test, Port Loop, V.54 Loop, Far V.54 Loop
Default: No Test (Loop Down)
The Test Details screens provide the following user-selectable prompts:
Prompt Function
Start BERT Starts the specified BERT.
Stop BERT Stops the currently running BERT.
Error Inject Injects a bit error.
Reset Errors Resets the current error count.
