The Trunk Alarm screen contains an entry for each trunk. There is always an entry in the navigation panel for each trunk regardless of whether it has alarms.

The screen displays two tabs for digital trunks:

• Alarms – Current alarms appear in red on the Alarm tab.

• 24-Hour Performance History – This tab provides a 24-hour view of errors that occur on the line. If no errors have occurred within the last 24-hours, the table displays zero or blank values.
