Parameters for setting the alarm options

...................................................................................................................................................................................................................................
Introduction
The ITM-CIT offers additional alarm control options. You can either stop an alarm
from being presented on the ITM-CIT or delay its presentation (or disappearance) from
the Current Alarms screen.
An alarm may be stopped by configuring an option called the Lining Up mode.
The other alarm control option allows to set a Raise/Clear delays on the Station Alarm
before the alarm indication is raised and/or cleared. Furthermore, it is possible to set its
dependency on alarm suppression network element on the ITM-CIT. This is achieved
with the Station Alarms Raise/Clear Delays.
It could happen during event monitoring that an alarm disappears from the window,
very quickly after being displayed. These alarms are usually due to an event else where
in the network and disappears because they are resolved by the system. In order to
avoid this "on/off flickering" of alarms, you can set a delay for the raise and clear time
of those alarms. In this way, the alarm condition is re-evaluated over the desired time
delay and will be presented and/or disappear from the ITM CIT if the condition
remains true and that delay time is exceeded.
Lining up mode
When a network element is put in to lining-up mode, no alarms are reported, however
any other communication error will still be reported. This prevents the system from
becoming cluttered with unnecessary alarms during installation or maintenance actions
on the network element. Any existing alarms for the network element are cleared when
the manager activates the Lining Up mode. This has the effect of moving all alarms to
the history store. The alarm status is re-evaluated by the network element when the
lining up is inactivated.
Dependency
Suppress Dependency on Station Alarms.
maintenance personnel wants to be able to decide if the Station Alarms will/or not be
suppressed when they are suppressed on the ITM-CIT. The Prompt and Deferred
maintenance alarm on the station alarm interface will be unaffected by the suppress
button. This option can be activated in run time.
Raise/clear delays
Raise/Clear Delay
before an alarm is raised, or cleared.
It could happen during event monitoring that an alarm disappears from the screen, very
quickly after being displayed. These alarms are usually due to an event elsewhere in
the network element and disappears because they are resolved by the system. In order
to avoid this "on/off flickering" of alarms, you can set a delay for the raise and clear
