Procedure: Select Fifteen-Minute PM Intervals on the Performance Monitoring Screen
Step 1 Open the electrical or optical card of choice. Double-click the card’s graphic in the main (node) view or
right-click the card and select Open Card. (Clicking a card once highlights the card only.)
Step 2 From the card view, click the Performance tab.
Step 3 Click the 15 min button.
Step 4 Click the Refresh button. Performance monitoring parameters display in 15-minute intervals
synchronized with the time of day.
Step 5 View the Current column to find PM counts for the current 15-minute interval.
Each monitored performance parameter has corresponding threshold values for the current time period.
If the value of the counter exceeds the threshold value for a particular 15-minute interval, a threshold
crossing alert (TCA) will be raised. The value represents the counter for each specific performance
monitoring parameter.
Step 6 View the Prev-N columns to find PM counts for the preceding 15-minute intervals.
