ES (Errored Seconds): Seconds during which one or more CRC 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. A CRC value is calculated for each 24 frames or
4608 bits of data and is transmitted with the framing information. The receiving
unit calculates a CRC value for the same 24 frames and compares the values.
If the values are unequal a CRC error event is logged.
FEBE (Far-End Block Errors): CRC errors reported by the remote
equipment.
Complete: Whether the interval register contains data for a complete
900-second interval.
This 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.
Error Events Counter A running total of CRC errors. Range 0–65535. This counter
resets when the near-end data is 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).
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.
Near and Far Tot A running total of the near- and far-end performance statistics.
