Recovery

  1. This measurement should have a zero value. A non-zero value means that the far-end of the association has stopped processing M3UA signaling. You can view Association status from the GUI main menu under SS7/Sigtran, and then Maintenance, and then Associations.
  2. Check the event history from the GUI main menu under Alarms & Events, and then View History, looking for Event ID 19227. Event ID 19227 will show exactly when the unsolicited ASP-DOWN-ACK was received.
  3. Verify whether the far-end of the association is undergoing maintenance.
  4. It is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729 for assistance if needed.
