Alarms Screen
The Alarms screen (Figure 4-3) displays the current alarm
status of the network and the DTE lines. The fields are
described as follows:
NET AND DTE A LARMS
The status lines shown in Table 4-B display the selected ele-
ment’s current network /DTE signal alarm state. Alarms are
determined by the following user-selectable thresholds:
A LARM S TATUS
The main body of the Alarms screen shows the current
count for parameters that may be used to trigger an alarm.
The Current column shows the total of errored seconds for
each alarm type. The Threshold column shows the values
set in the Alarm Configuration screen (Figure 4-13). Any
parameter that has a current value equal to or greater than its
non-zero threshold generates an alarm. Any parameter with
a threshold value of 0 is disabled from generating alarms.
The parameters shown on the Alarms Screen are
updated at five-second intervals.
R ESET A LARM R EGISTERS
