4. Monitoring the Unit

TBES (Bursty Errored Seconds): Contains the number of bursty errored seconds for the current interval. A bursty errored second is any second with more than one but less than 320 CRC errors.

LOFC (Loss of Frame Count): Contains the number of times that an LOF is declared.

Status: Contains the contents of the status events register. The status events register maintains a history of specific events that have occurred during an interval. Values include:

Y: Remote alarm indication signal (yellow alarm) received at the DSX-1 interface

L: Loss of signal detected at the DSX-1 interface

E: Excessive error rate threshold exceeded

F: Frame synchronization bit error detected

V: Line code violation detected

None: No significant events have occurred

Current Interval

The number of seconds which have elapsed in the current

Timer

15-minute interval. Maximum value is 900 seconds (15 minutes).

 

This counter resets every 15 minutes.

 

 

Error Events

A running total of CRC and OOF events. Total range = 0–65535.

Counter

Counter resets when the statistics are cleared.

 

 

Current Int

Performance data for the current 15-minute interval.

 

 

Interval xx

Historical performance data for up to 96 15-minute intervals

 

(24 hours) where the value of xx is from 01 to 96.

 

 

Worst Interval

Identifies the interval during which the most error events were

 

detected.
