Figure 4.42 Network Interface Test Details Screen
BERT Table on the Network Interface Test Details Screen
The BERT table lets you set the test parameters listed below.
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, Use Service, Idle, Channel 1...31
Default: Net
Specifies the pattern to be transmitted during a test for the selected port.
Values: Marks, QRSS, 511, 2047, 2
Default: QRSS
15
NOTICE:
The 2 pattern is the ITU (European) version, not the ANSI version.
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
Selects the channels with a service to BERT (refer to the "Service Table
Screen" on page 4-19).
Sets the bit rate to BERT for each selected channel. If "Nx64K" is selected,
the ones density requirements of the E1 network line must be ensured. If
"Nx56K" is selected, ones density for the selected DS0 channel is maintained.
Values: Nx56K, Nx64K
Default:Nx64K
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,
