The Performance prompt near the bottom of the Network screens displays a

Performance 24 Hour screen (Figure 4.8), 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

more than one but fewer than 320 CRC6 errors occurred.

LOFC

frame is declared. A loss of frame is declared after 2.5 seconds of continuous

loss of signal or OOF.

CRCES

CRC is a method of confirming the integrity of received data.
