Another special feature of the ISDN-PRI card is the ability to track and log performance
statistics on incoming and outgoing ISDN traffic for each D channel. The Performance
Monitoring screen is accessed from the Configure screen by highlighting the D channel with
the cursor and pressing the "P" command from the Menu of Actions. Figure 5-22 shows the
Performance Monitoring screen.

Calling statistics are kept for one hour periods for the current hour and the previous 24
one-hour periods. As each hour passes, the statistics for the twenty-fourth hour are dropped.
Users can scroll through the current figures using the "U" (pgUp) and "D" (pgDn) commands
from the Menu of Actions.
Since the system does not log statistics incrementally (i.e., second by second), the only way
to have truly current figures is to use the "R" (Refresh) command from the Menu of Actions
which redraws the screen with the new information.
