The following Network Error Statistics are collected for the selected port:

„

ES (Errored Seconds): Seconds during which one or more ESF error events 
occurred.

„

SES (Severely Errored Seconds): Seconds during which more than 
320 cyclic redundancy check (CRC) error events or at least one Out of Frame 
(OOF) event occurred.

„

FEBE (Far-End Block Errors): Errors reported by the remote equipment.

„

Complete: Whether the interval register contains data for all 900 seconds of 
the interval.

Fields on this screen include:

Field . . . 

Contains . . . 

Current Interval Timer

The number of seconds which have elapsed in the current 
15-minute interval. Maximum value is 900 seconds 
(15 minutes). This counter is reset every 15 minutes. 
When zero, the port is disabled.

Error Events Counter

A running total of CRC errors. Range 0–65535. This counter 
resets when the near-end data is cleared. When zero, the port is 
disabled.

Historical performance data for up to 96 15-minute intervals 
(24 hours). When blank, the port is disabled.

Worst Interval

The number of the interval with the worst (highest) performance 
data for both the near- and far-end statistics. If two or more 
intervals are equal, the oldest interval is displayed. 
When blank, the port is disabled.

Near and Far Tot

A running total of the near- and far-end performance statistics.
