14.3.3 Filtering Alarms
The alarm display can be filtered to prevent display of alarms with certain severities or alarms that
occurred between certain dates and times. You can set the filtering parameters by clicking the Filter
button at the bottom-left of the Alarms window. You can turn the filter on or off by clicking the Filter
tool at the bottom-right of the window. CTC retains your filter activation setting. For example, if you
turn the filter on and then log out, CTC keeps the filter active the next time you log in.
14.3.4 Viewing Alarm-Affected Circuits
A user can view which ONS 15454 SDH circuits are affected by a specific alarm by positioning the
cursor over the alarm in the Alarm window and right-clicking. A shortcut menu appears (Figure 14-2).
AutoDelete Cleared
Alarms check box
If checked, CTC automatically deletes cleared alarms.
Filter tool Enables or disables alarm filtering in the card, node, or network view. When
enabled or disabled, this state applies to other views for that node and for
all other nodes in the network. For example, if the Filter tool is enabled in
the node (default login) view Alarms window, the network view Alarms
window and card view Alarms window also have the tool enabled. All other
nodes in the network also have the tool enabled.
