1077 - GTT Action TCAP ERROR DISCARDED MSU

This UIM indicates that the TCAP Error Action executed and UIMREQD is ON.

There are two cases in which this alarm is generated:

1. When this GTT Action (DISC, UDTS or TCERR) is provisioned as the main GTT Action for the translation (GTA)
2. When this GTT Action (DISC, UDTS or TCERR) is provisioned as the default action (ENT/CHG-GTTACT:DEFACTID) for some other GTT Action (FWD, DUP, SFTHROT or SCPVAL) that is provisioned for the translation (GTA), and this default action is executed when the main GTT Action fails.

When these DISCARD Actions are executed as main GTT Action for the translation, the output will look like the following example:

Example

6053.1077    CARD 1101     INFO    GTT Action TCAP ERROR DISCARDED MSU
             OPC=   1-001-4        DPC=   1-001-5
             CDPA:  NI=0  RI=0  GTI=02  SSNI=1  PCI=1
                    TT=010  NP=--  NAI=---  ADDR=9818316478
                    PC=   1-001-1        SSN=016
             CGPA:  NI=0  RI=0  GTI=02  SSNI=1  PCI=1
                    TT=011  NP=--  NAI=---  ADDR=9910929095
                    PC=   1-002-3        SSN=049
             Op-Code=--- Action Set=tcapset
             Report Date:03-01-03  Time:16:45:01

When these DISCARD Actions are executed as the "failure outcome" of the main GTT Action for the translation, this UIM generates an additional line displaying the cause of that main GTT Action failing:

Recovery:

1. To prevent the MSU from being discarded post-GTT, remove the "TCAP Error" GTT action associated with the GTT translation.
   If you want to suppress this UIM, turn off the UIMREQD option for the given “TCAP ERROR” GTT action.
