Recovery

1. If all is well, this measurement should have a zero value. If non-zero, the association has been closed due to lack of response from the far-end. The MP server will begin periodic attempts to reconnect to the SG.
2. Otherwise:
   1. Transport status can be viewed at Main Menu, and then Transport Manager, and then Maintenance, and then Transport.
   2. Look in the event history at Main Menu, and then Alarms & Events, and then View History Event 19405 - Transport closed due to a lack of response (refer to the DSR Alarms and KPIs Reference for details about this event.
   3. Verify IP connectivity between the MP server and the SG.
   4. Determine if the far-end of the association is congested, possibly causing slow response times on the association.
   5. Check the IP network between the MP server and the SG for excessive retransmissions.
   6. It is recommended to contact unresolvable-reference.html#GUID-F069C6FD-5BA3-4F31-AE9E-A187D5B5F729 for assistance if needed.
