1232 - SCCP Encode Failure

This message indicates that there is an SCCP encode failure. This UIM may be triggered by a service when network crossing (ANSI <-> ITU) is attempted, or the problem could originate at the far end.

Example

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

GTCNV:Cld ANSI->ITU fail

Invalid CdPA GTI for ANSI-to-ITU GTCNV table: ANSI MSU is GTT translated to ITU, CdPA GTA record has NGTI as not provisioned, so GTT is using Default GTT (GTCNV table) to convert CdPA, but CdPA GTCNV Selectors (GTI, TT) are not found in GTCNV table

GTCNV:Clg ANSI->ITU fail

Invalid CgPA GTI for ANSI-to-ITU GTCNV table: ANSI MSU is GTT translated to ITU, CgPA RI=GT, SCCP Conversion used Default GTT (GTCNV table) to convert CgPA, but CgPA GTCNV Selectors (GTI, TT) are not found in GTCNV table

Recovery

Contact the distant end node this message refers to and verify action is being taken to correct the SCCP encode failure problem.

1. Determine whether the MSU was processed by a service that does not support network crossing (ANSI <-> ITU).
   The following are some of the services that do not support network crossing (not a complete list):

   • AIQ
   • APORT
   • GPORT
   • ATINPQ
   • EIR
   • INPQ
   • MNP SMS
   • VFLEX
2. If the MSU was processed by a service that does not support network crossing, check the originating network domain and the destination network domain to determine whether network crossing (ANSI <-> ITU) occurred. If so, the MSU was discarded and UIM 1332 was issued. Correct the network crossing problem.
3. If the problem is not caused by a service that does not support network crossing, contact the distant end node that this message refers to and verify that action is being taken to correct the SCCP encode failure problem.
