4.3 Alarms Screen
The ‘Alarms’ screen (Screen 4-3) is used to view the current
alarm status of the network and DTE lines. The fields are
described as follows:
Element: Pressing the <spacebar> toggles this field for
selection of either the ‘
NEAR ’ or ‘ FAR ’ unit. ‘ NEAR ’ refers
to the unit to which the terminal is connected. ‘ FAR ’ refers
to the unit at the other end of the network E1 span.
NET /DTE Alarms: These status lines display the selected
element’s current network/DTE signal alarm state. Alarms
are determined by the following user selectable thresholds.
Table 4-1 Alarm Indications
(alarm status): The main body of the ‘Alarms’ screen dis-
plays the current count for parameters that may be used to
trigger an alarm.
The ‘ Current ’ column shows the total of the preceding 15
one-minute intervals. At the end of each one-minute inter-
val, the oldest minute of the 15-minute interval is discarded.
The ‘ Threshold ’ column shows the values set in the
‘Alarm Configuration’ screen (Screen 4-7 on page 4-10).
Any parameter that has a current value equal to or greater
than its non-zero threshold will generate an alarm. Any
parameter with a threshold value of ‘
0 ’ is disabled from
generating alarms.
