Network Performance/Summary Screen

In addition to the error parameters found in the Error Status and Alarm

Thresholds Table on page 3-7, the following error parameters are included on

the Network Performance/Summary table:

BES

The Bursty Error Seconds (BES) refers to 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

The Cyclic Redundancy Check Errored Seconds (CRCES) is a method of

confirming the integrity of received data.

Beneath the Performance/Summary table are two buttons: “Performance 24

Hour” and “Performance 30 Day.” Clicking either of these buttons will

display a detailed summary of the error events that have occurred during each

15-minute interval of the past 24 hours (Figure 3.6) or during each interval

(day) of the past 30 days (Figure 3.7).
