Configuring the ANSI to ITU-N SCCP Conversion Option

This procedure is used to set the value of the called party/calling party address Reserved for National Use bit that is used during SCCP conversion when global title translation routes the message to the ITU national network. The called/calling party address Reserved for National Use bit is set using the chg-sccpopts command and with this parameter.

:cnvainat – the value of the called party/calling party address Reserved for National Use bit used during SCCP conversion when the MSU is routed to the ITU national network. The values for this parameter are:

0 – the Reserved for National Use bit is not reserved for national use.
1 – the Reserved for National Use bit is reserved for national use.

The system default value for this parameter is 1.

The ANSI/ITU SCCP Conversion feature must be enabled and turned on to change this parameter value with the chg-sccpopts command. The CNVAINAT field in the output of the rtrv-sccpopts command output is shown when the ANSI/ITU SCCP Conversion feature is enabled and turned on. If the CNVAINAT field is not shown in the output of the rtrv-sccpopts command output, perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enable the ANSI/ITU SCCP Conversion feature.

If any parameter is not specified with the chg-sccpopts command, that parameter value will not be changed.

For more information on the ANSI/ITU SCCP Conversion feature, refer to the ANSI/ITU SCCP Conversion Feature section.

Display the existing value for the cnvainat parameter value by entering rtrv-sccpopts command. This is an example of the possible output.

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

If the CNVAINAT field is not shown in the output of the rtrv-sccpopts command, the ANSI/ITU SCCP Conversion feature is not enabled and turned on. For this field to be shown in the rtrv-sccpopts output, and to change these values, the ANSI/ITU SCCP Conversion feature must be enabled and turned on. Perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enable and turn on the ANSI/ITU SCCP Conversion feature. After the ANSI/ITU SCCP Conversion has been enabled and turned on, continue the procedure with 2

If the CNVAINAT field is shown in the rtrv-sccpopts output, continue the procedure with 2.
Change the cnvainat parameter value by entering the chg-sccpopts command with the cnvainat parameters. For this example, enter this command.
chg-sccpopts:cnvainat=0

If any parameter is not specified with the chg-sccpopts command, that parameter value will not be changed.

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

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

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.
