Performance Screens 4-9
(performance
data)
The main body of display data consists of error events for three different
periods: The first display line shows the data accumulating for the current interval
(from 0 to 900 seconds). The second line shows the totals for the last 24-hour
period (or the last 96 fifteen-minute intervals). The third line shows the 30-day
totals.
The remaining lines of this screen show the data for any intervals containing
errors. Interval 1 is the most recently stored 15-minute interval and interval 96 is
the oldest in the current 24-hour period. On the 30-day screens, interval 30 is the
oldest 1 -day interval in the current 30 -day period. The real time (or date on the
30-day screens) of the interval beginning is shown in the first column.
If more than five errored intervals have elapsed, PAGE-DN appears to the left of
the performance data. Pressing Enter on this field displays the next five errored
intervals. PAGE-UP appears once PAGE -DN is used. Pressing Enter on PAGE -UP
displays the previous five errored intervals. Only intervals that contained errors are
displayed, which eliminates rows of zeroes. If an interval is not displayed, no
errors were detected in that time period.
The parameters shown on the Performance screens are updated at five-second intervals.
Per AT&T Technical Reference TR54016, the Standard 24 Hour and Standard 30
Day performance data consists of Errored Seconds (ES), Bursty Errored Seconds
(BES), Severely Errored Seconds (SES), Unavailable Seconds (UAS), Loss of
Frame Count (LOFC), and Controlled Slip Seconds (CSS).
The Enhanced 24 Hour and Enhanced 30 Day screens show data for CRC Errored
Seconds (CRCES), Out of Frame Seconds (OOFS), Loss of Signal Seconds
(LOSS), Alarm Indication Signal Seconds (AISS), Remote Alarm Seconds (RAS),
and BPV Seconds (BPVS).
For generic 54016 far-end devices, only the standard telco 24-hour performance data is
displayed. 30-day data is not available.
