4-10 T ERMINAL O PERATION
Completed Days
This field displays the number of days which are included in the 30 -day totals.
Completed Intervals
This field displays the number of 15-minute intervals in the last 24-hour period
since the registers were last cleared (a 24 -hour period may contain up to 96
intervals).
24 Hr.% Error Free
This field displays the percentage of error-free seconds within the last 24 hours or
since the event registers were last cleared. It is based only on the ES and UAS
parameters.
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 of the intervals that
contained errors. Interval 1 is the most recently stored interval and interval 96 is
the oldest 24 -hour interval. Interval 30 is the oldest 30-day interval (on the
30-day screen). The real time (or date on the 30-day screen) 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 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 Bipolar Violation Seconds (BPVS).
For generic 54016 far-end devices, only the standard telco 24-hour performance data is
displayed. 30-day data is not available.
