ES Displays the number of asynchronous errored seconds detected since the
BERT began or since error statistics were last cleared. This parameter
includes bit error seconds and sync loss seconds.
%EFS Displays what percent of the total BERT 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.
Test Details Screens
The Test Details screens let you set some test parameters and view other read-
only parameters. These screens are also used to initiate a BERT or Loop Test.
The Network Interface Test Details screen is shown in Figure 3.40, and its
parameters are described below the figure. The Serial Interface Test Details
screen is shown in Figure 3.41, followed by a description of its parameters.

BERT Table on Network Interface Test Details Screen
The BERT table 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 is selected.
Values: Idle Channels, Channel 1...31, Net, Use Service
Default: Net
Service Selects the channels with a service to BERT (refer to Figure 3.12 on
page 3-17).
Channel Rate 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
