Loop Lets you specify the type of loop test (if any) to be performed on the selected
serial interface.
Values: No Test, Port, V.54, Far.V.54
Default: No Test
Setting Lets you specify the direction towards which the BERT pattern is to be sent.
Values: Net, DTE
Default: Net
Pattern Lets you specify the pattern to be transmitted during a BERT for the selected
port.
Values: QRSS, 511, 2047, 2^15, Spaces, Marks
Default: QRSS
NOTICE: The 2
15
pattern is the ITU (European) version, not the ANSI version.
Length Lets you specify the length of time the BERT should run for the selected
interface.
Values: 15 Minutes, 30 Minutes, 1 Hour, 24 Hours, Continuous
Default: 15 Minutes
Sync Display-only field shows the state of pattern sync during a BERT. If no
BERT is in progress, “No Test” is displayed. If a BERT 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 Display-only field shows the amount of time (in seconds) that has elapsed
since a BERT began or, if completed, the total test time.
Bit Errors Display-only field shows the number of bit errors detected since the BERT
began or since error statistics were last cleared.
ES Display-only field shows the number of asynchronous errored seconds that
have been detected since the BERT began or since error statistics were last
cleared. This parameter includes bit error seconds and sync loss seconds.
% EFS Display-only field shows what percent of the total test time ran error free.
This ratio is derived from the number of error-free seconds divided by the
number of seconds accumulated in Elapsed Time.
Cmd Lets you control basic aspects of the BERT performed, including the injection
of errors during test.
Values: Stop, Reset, Error Inject, Start
Default: Stop
