1045 - SCCP did not route - DPC congested

The SCCP did not route a message because the destination point code (DPC) was congested. The message was discarded.

Example

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

Recovery

This indicates an SCCP message was discarded due to congestion at a distant node. Maintenance personnel should monitor the network and verify the nodes congestion status changes to zero (no congestion).

Note:

A transfer controlled (TFC) should have been received on the link to indicate congestion to this node. When the congestion status changes, the congestion status indicator in the flow control messages indicates what message type priorities can be transmitted to the distant node. If the condition persists, follow normal company procedures in dealing with congestion at distant nodes.
