1344 - MSU discarded: In-Service Thresholding

The EAGLE 5 ISS discarded an SCCP message because the MRN or MAP Group selected by GTT does not have enough available weight to satisfy the In-Service threshold.

Example

This output indicates an error against the original destination rather than the redirected destination.

Recovery

1. Use rtrv-mrn and rtrv-map to determine the MRN and MAP Group information for that PC/PC+SSN combination.
2. Validate that the In-Service Threshold (THR) parameter is set correctly for each Group.

   If not, use the chg-mrn or chg-map command to change the THR parameter to the correct value.

3. If THR is correct, validate that the weight parameter is set correctly for each member of the group.

   If not, use the chg-mrn or chg-map command to alter the weights to the correct values.

4. Use rept-stat-dstn to determine which PC/PC+SSNs are not available.

   Perform corrective maintenance to get the unavailable PC/PC+SSNs back into service. Potential causes for unavailability are link deactivation, prohibited routes, network congestion or subsystem outages.
