DTE Alarms These status lines display the selected element’s current DTE signal alarm state
(Table 4-3). Alarms are determined by the selectable thresholds in the Alarm
Configuration screen (see Figure 4-8 on page 4-17).
Selectable thresholds in the Alarm Parameters screen and the DTR Alarm may be
enabled or disabled for the ports in the Port Parameters screen.
(alarm status)
The main body of the Alarms screen shows the current count for parameters that
may be used to trigger an alarm.
The Current column displays a total of the preceding 15 one -minute intervals. At
the end of each one-minute interval, the oldest minute of the 15 -minute interval is
discarded.
The Threshold column displays the values set in the Alarm Configuration screen
(see Figure 4-8 on page 4- 17). Parameters having a current value equal to or
greater than its non-zero threshold generates an alarm. Any parameter with a
threshold value of zero is disabled from generating alarms.
The parameters shown on the Alarms screen are updated at approximately five-second
intervals.
Power Loss Seconds
This field displays the number of seconds that the element has been without power
since this value was last cleared.
