Performance Screens
The “Performance” prompt near the bottom of the Network screens displays a
Performance 24 Hour screen (Figure 4.9), which provides a summary of the
error events that have occurred during each interval of the past 24 hours. In
addition to the parameters already defined on the Error Status and Alarm
Thresholds Table on page 4-9, the following parameters are included on the
Performance screens.
BES Sets the Bursty Error Seconds (BES) threshold. A BES is a 1-second period
during which at least more than one but fewer than 320 CRC6 errors
occurred.
CRCES Sets the Cyclic Redundancy Check Errored Seconds (CRCES) threshold. A
CRC is a method of confirming the integrity of received data.
