Note 1:

These messages are mutually exclusive.
If an alarm has timed out, and occurred it will not show the Alarm Count Stop message as this is implied by the fact that the alarm message has already been recorded.
The Alarm Count Start and Alarm Count Stop messages indicate a line that is going into and out of alarm, but is not there long enough for an alarm to be flagged. See Example 1.
