Table 11-6 lists the Conditions window column headings and the information recorded in each column.
11.2.5 History Window
The History window displays historical alarm data. It also displays conditions, which are Not Alarmed
activities such as timing changes and threshold crossings. For example, protection-switching events or
performance-monitoring threshold crossings appear here. The ONS 15600 can store up to 3,000 total
alarms and conditions: 750 Critical alarms, 750 Major alarms, 750 Minor alarms, and 750 conditions.
When the limit is reached, the ONS 15600 begins replacing the oldest items. The History window
presents several alarm history views:
•
The History > Session window appears in network view, node view, and card view (Figure 11-4). It
shows alarms and conditions that have occurred during the current user CTC session.
•
The History > Shelf window appears only in node view. It shows the alarms and conditions that have
occurred on the node since CTC software was originally activated for that node.
•
The History > Card window appears only in the card view. It shows the alarms and conditions that
have occurred on the card since CTC software was installed on the node.
Note
In the Preference dialog box General tab, the Maximum History Entries value applies to only the Session
window.
Tip
Double-click an alarm in the History window to display the corresponding view. 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.
