Performance Screens 45
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
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 during that time period.
The parameters shown on the Performance screens are updated at five-second
intervals.
Per AT&T Technical Reference (TR) 54016, the Standard 24 Hour and Standard
30 Day performance data consists of Errored Seconds (ES), Unavailable Seconds
(UAS), Bursty Errored Seconds (BES), Severely Errored Seconds (SES), 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 Bipolar Violation Seconds (BPVS).
For generic TR 54016 far-end devices, only the standard telco 24- hour performance
data is displayed. 30 - day data is not available.
