If the sum result is longer than the Alarm Occurrence Period Threshold or Alarm Occurrence Times Threshold, an alarm so called Transient Count Alarm is triggered.

The congestion of the M3UA signaling link causes the M3UA to discard user messages.

The M3UA reports the congestion primitive to the SCCP, requiring that the SCCP and the SCCP users lessen the MSUs to eliminate the congestion.

Too many messages are sent to the M3UA link, so the link is congested.

In the Brows Alarm window on the LMT, check whether the alarm is cleared within 10 seconds.
Yes => The alarm handling is complete.

Add M3UA signaling links to share load and then check whether the alarm is cleared.
Y => The alarm is cleared. The alarm handling is complete.
