Performance Screens

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

Performance 24 Hour screen (Figure 4.7), 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 4-8, 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.

LOFC

The Loss of Frame Count (LOFC) represents the number of time a loss of

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

loss of signal or OOF.

CRCES

Sets the Cyclic Redundancy Check Errored Seconds (CRCES) threshold. A

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