Changing the MTP-Routed GTT Options

This procedure is used to change the MTP-routed GTT options using the chg-sccpopts command with these parameters.

:mtprgtt – This parameter specifies whether global title translation is performed on an MTP-routed message and how the message is routed after global title translation is performed on the message. This parameter has three values.

• off - global title translation is not performed on the MTP-routed message.
• usemtppc - global title translation is performed on the MTP-routed message and is then routed to the original DPC.
• fullgtt - global title translation is performed on the MTP-routed message and is then routed to the translated DPC.

:mtprgttfallbk – this parameter specifies whether an MTP-routed message is MTP-routed after global title translation on the message has failed. This parameter has two values.

• mtproute - perform MTP-routing on the message if global title translation on the message fails.
• gttfail - discard the message if global title translation on the message fails. Send a UDTS if required.

This procedure can be performed only if the MTP Routed GWS Stop Action feature or the MTP Msgs for SCCP Apps feature is enabled. The status of these features is shown in the rtrv-ctrl-feat output.

1. Display the existing default GTT mode values by entering the rtrv-sccpopts command.

   This is an example of the possible output.

   SCCP OPTIONS
   -------------------------------
   MTPRGTT                     off
   MTPRGTTFALLBK          mtproute

   The rtrv-sccpopts output contains other fields that are not used in this procedure. If you wish to see these fields, refer to the rtrv-sccpopts command description in Commands User's Guide.

   If the MTPRGTT value is either usemtppc or fullgtt, or the MTPRGTTFALLBK value is gttfail, then either the MTP Routed GWS Stop Action feature or the MTP Msgs for SCCP Apps feature is enabled. The MTPRGTT or MTPRGTTFALLBK values can be changed. Continue the procedure with 3.

   If the MTPRGTT value is off and the MTPRGTTFALLBK value is mtproute, continue the procedure with 2.

2. Display the status of the MTP Routed GWS Stop Action feature or the MTP Msgs for SCCP Apps features by entering the rtrv-ctrl-feat command.

   This is an example of the possible output.

   Zero entries found.
   
   
   The following features have expired temporary keys:
   
   Feature Name              Partnum
   Zero entries found.

   If either the MTP Routed GWS Stop Action feature or the MTP Msgs for SCCP Apps features are enabled, continue the procedure with 3.

   If neither the MTP Routed GWS Stop Action feature or the MTP Msgs for SCCP Apps features are enabled, enable the desired feature by performing one of these procedures.

   • To enable the MTP Routed GWS Stop Action feature, perform the “Activating the MTP Routed GWS Stop Action Feature” procedure in Database Administration GWS User's Guide.
   • To enable the MTP Msgs for SCCP Apps feature, perform the “MTP Msgs for SCCP Apps Activation Procedure” in one of these user's guides to enable the feature.
     • A-Port User's Guide
     • IS41 GSM Migration User's Guide
     • MO SMS User's Guide

   After the desired feature has been enabled, continue the procedure with 3.

3. Change the MTP-routed GTT option values using the chg-sccpopts command and with either the mtprgtt or the mtprgttfallbk parameters, or both parameters.

   For this example, enter this command.

   chg-sccpopts:mtprgtt=fullgtt:mtprgttfallbk=gttfail

   When the chg-sccpopts command has successfully completed, this message should appear.

   CHG-STPOPTS: MASP A - COMPLTD

4. Verify the changes using the rtrv-sccpopts command. This is an example of the possible output.

   MTPRGTTFALLBK           gttfail

5. Back up the new changes using the chg-db:action=backup:dest=fixed command. These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

   BACKUP (FIXED) : MASP A - Backup starts on active MASP.
   BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
   BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
   BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
