BERT Table on the Network Interface Test Details Screen
The BERT table provided on the Test Details screen lets you set the test
parameters listed below.
Setting Displays the bandwidth on which you wish to perform the BERT. The
available values for this parameter depend on which interface you select.
Values: Idle, Channel 1...24, Net, Use Service
Default: Net
Service Selects the channels with a service to BERT (see Services Screen on
page 3-18).
Channel Rate Sets the bit rate to BERT for each selected channel. If “Nx64K” is selected,
the ones density requirements of the T1 network line must be ensured. If
“Nx56K” is selected, ones density for the selected DS0 channel is maintained.
Values: Nx56K, Nx64K
Default: Nx64K
NOTICE: The Service and Channel Rate parameters will appear only on Network
screens.
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 the test should run for the selected port.
Values: 15 minutes, 30 minutes, 1 hour, 24 hours, Continuous
Default: 15 minutes
Also on this screen, you can view the following read-only parameters:
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.
