0320 - REPT-MTPLP-SUST: Sustained circ rt(cong)

The system automatically tests for circular routing when congestion occurs on an ANSI signaling link. If the routing data was provisioned incorrectly, or was corrupted, MSUs could be routed in an endless circular route. The incorrect routing data could be on the system or at a remote STP. This message indicates that circular routing has been detected.

*C 0014.0320 *C DPC 011-210-*   REPT-MTPLP-SUST: Sustained circ rt(cong)

                MEMBER=011-210-007

Alarm Level: Critical

Recovery

1. Enter the following command to check the routing information for the specified DPC:
   rtrv-rte

   If the problem is in the routing table of an adjacent node, contact the node (identified in the rtrv-rte command output) to resolve the circular routing problem. If the routing information is correct, continue with 4. If there is an error in the routing information, continue with 2.

2. Enter the following command to delete the route in the error message from the database:
   dlt-rte:aaaa=xxx-xxx-xxx:lsn=yyyy

   where aaa = dpc, dpca, dpci, or dpcn xxx-xxx-xxx = destination point code and yyyy = the linkset name associated with the route.

3. Refer to the "Adding a Route" procedures in Database Administration Manual - SS7 to enter the correct route information.
4. Enter the following command to reset the destination circular routing status:
   rst-dstn:dpc=x-x-x

   where x-x-x = the destination point code of the destination.
