Checking Statistics 4-31
CSX WAN Configuration
Following are descriptions of each of the errors which are recorded in this
window.
RsPort#
A unique number assigned to the synchronous port.
FCS Err
Displays the total number of frames with an invalid frame check sequence that
were input from the port while its state was up or test, since the system was last
initialized.
Transmit Underrun
Displays the total number of frames that failed to be transmitted on the port
because data was not available to the transmitter in time while its state was up or
test
, since the system was last initialized.
Receive Underrun
Displays the total number of frames that failed to be received on the port because
the receiver did not accept the data in time while its state was up or test, since the
system was last initialized.
Interrupted
Displays the total number of frames that failed to be received or transmitted on
the port due to loss of modem signals while its state was up or test, since the
system was last initialized.
Aborted
Displays the total number of frames aborted on the port due to receiving an abort
sequence while its state was up or test, since the system was last initialized.
Synchronous Port Signals
The Synchronous Port Signals window contains a line for each input and output
signal on each synchronous port. The information in this window includes the
signal types that the synchronous port has received or sent, as well as the current
state of each signal, and the number of state changes of each signal.
To open this window:
1. Click on . A pull-down menu will appear.
2. Drag down to Synchronous Port Signals and release. Figure 4-16 will
