You can reset the user performance registers via the ClrStats selection on the

Performance Statistics screen.

NOTE:

ClrStats only resets the user events. Telco events are cleared during a

power-on reset.

There are four sections to the Network Performance Statistics screen:

 Summary Information

 Interval Table

 Worst Interval

 24-Hour Totals

Summary Information

Summary information provides the following information:

 Current Interval Timer – displays the number of seconds that have elapsed

in the current 15-minute interval.

 ESF Error Events – displays the number of ESF frames with either a CRC

error or an OOF event.

The ESF Error Event statistic is

not

reset every 15 minutes. If the counter

reaches 65,535, it remains at this value until reset.

The Telco counter for ESF Error Events can only be cleared by a reset

command from the network or a reset of the device itself.

The User counter for ESF Error Events can only be reset by selecting the

ClrStats option or by resetting the device.

Interval Table

Network performance statistics are kept for each 15-minute interval over the past

24-hour period. There are six types of statistics recorded:

 Errored Seconds (ES) – The number of errored seconds for the current

interval. An errored second is any second with one or more ESF error events.

The maximum is 900 seconds.

 Unavailable Seconds (UAS) – The number of unavailable seconds for the

current interval. An unavailable second is any one second interval when

service is unavailable. (Detection occurs with 10 consecutive unavailable

seconds.) The maximum is 900 seconds

 Severely Errored Seconds (SES) – The number of severely errored

seconds for the current interval. A severely errored second is any second

with 320 or more CRC errors, or any second with one or more OOF events.

The maximum is 900 seconds.
