Setting Displays the bandwidth on which you wish to perform the BERT. The
available values for this parameter depend on which interface is selected.
Values: Net, DTE
Default: Net
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 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 at the bottom of the screen lets you specify the type of Loop
test to be performed. The types of tests available for the Serial interface are
shown below. Loopback diagrams are illustrated in Appendix A, Figure A.1.
Values: No Test, Port Loop, V.54 Loop, Far V.54 Loop
Default: No Test (Loop Down)
