Solution 2387164.1 : MTP Routed GTT Is Not Triggering

Applies to:

Oracle Communications EAGLE (Software) - Version EAGLE 46.5 and later
Information in this document applies to any platform.

Goal

Problem Description
---------------------------------------------------

During MTP Routed GTT testing for new STP implementation, unable to get the GTT to trigger for MTP routed messages even though the configuration according to the documentation were done - ie. feature has been activated and the SCCPOPTS table set as follows:
mtprgtt=fullgtt and mtprgttfallbk=gttfail.

Solution

Per the customer documentation:

"In addition to the actions that were performed in previous releases, global title translation and GTT Actions are performed on MTP routed MSUs similar to the existing global title translation GTT handling for GT routed MSU’s.
Global title translation on MTP routed MSUs is performed if the service handling results in Fall through to GTT or if the GTT required option in the service selector is set to on for the service relayed MSU."

Above statements from customer document implies that the MTP routed GTT is performed on MSUs which hits the SCCP services and then fall through to GTT, or if the GTT required option in the service selector is set to on for the Service relayed MSUs.

The customer was not having any SCCP services activated in the system.
