Step 3 Return to your originating procedure (NTP). 
DLP-G116 View Alarm or Event History
Step 1 Decide whether you want to view the alarm message history at the node, network, or card level.
Step 2 To view node alarm history:
a. In node view, click the History > Session tabs to view the alarms and conditions (events) raised 
during the current session.
b. Click the History > Node tabs. 
If you check the Alarms check box, the node’s alarm history appears. If you check the Events check 
box, the node’s Not Alarmed and transient event history appears. If you check both check boxes, 
you will retrieve node history for alarms and events. 
c. Click Retrieve to view all available messages for the History > Node tab.
Note Alarms can be unreported when they are filtered out of the display using the Filter button in 
either tab. See the “DLP-G126 Enable Alarm Filtering” task on page 8-25 for information.
Tip Double-click an alarm in the alarm table or an event (condition) message in the history table to 
display the view that corresponds to the alarm message. For example, double-clicking a card 
alarm takes you to card view. In network view, double-clicking a node alarm takes you to node 
view.
Step 3 To view network alarm history:
a. From the View menu, choose Go to Network View.
b. Click the History tab.
Alarms and conditions (events) raised during the current session appear.
Step 4 To view card alarm history:
a. From the View menu, choose Go to Previous View.
b. Double-click a card on the shelf graphic to open the card-level view. TCC2/TCC2P cards do not 
have a card view.
Purpose This task is used to view past cleared and uncleared ONS 15454 alarm 
messages at the card, node, or network level. This task is useful for 
troubleshooting configuration, traffic, or connectivity issues that are 
indicated by alarms.
