Changing the ANSI/ITU SCCP Conversion Options

This procedure is used to change the options used for the ANSI/ITU SCCP Conversion feature using the chg-stpopts command. The options are:

:cnvcgda – The CGPA point code in ANSI SCCP messages are discarded if the point code or alias point code of the destination network type is not defined.

:cnvcgdi – The CGPA point code in ITU-I SCCP messages are discarded if the point code or alias point code of the destination network type is not defined.

:cnvcgdn – The CGPA point code in ITU-N SCCP messages are discarded if the point code or alias point code of the destination network type is not defined.

:cnvcgdn24 – The CGPA point code in ITU-N24 SCCP messages are discarded if the point code or alias point code of the destination network type is not defined.

:cnvclgitu – Enables or disables ITU-X to ITU-Y SCCP CGPA Conversion.

:gtcnvdflt – SCCP messages are routed using system defaults when an appropriate entry is not found in the Default GT Conversion Table.

The values for each of these parameters, shown in the rtrv-stpopts output, is either yes or no. The system default values for these parameters is no.

These parameters of the chg-stpopts command are optional. For any parameters not specified with the chg-stpopts command, the values for these parameters are not changed.

The current values for these parameters are shown in the CNVCGDA, CNVCGDI, CNVCGDN, CNVCGDN24, and GTCNVDFLT fields in the output of the rtrv-stpopts command.

The ANSI/ITU SCCP Conversion Feature must be enabled to change these parameter values with the chg-stpopts command. The CNVCGDA, CNVCGDI, CNVCGDN, CNVCGDN24, and GTCNVDFLT fields in the output of the rtrv-stpopts command are shown when the ANSI/ITU SCCP Conversion feature is enabled. If the CNVCGDA, CNVCGDI, CNVCGDN, CNVCGDN24, and GTCNVDFLT fields are not shown in the output of the rtrv-stpopts command, perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enabled the ANSI/ITU SCCP Conversion feature.

Note:

The ANSI/ITU SCCP Conversion feature can only be permanently enabled.

Note:

If the value of the CNVCGDA, CNVCGDI, or CNVCGDN value in the rtrv-stpopts output is no when this procedure is completed, and the calling party address of the MSU cannot be converted when the MSU is processed, then the MSU is discarded.

1. Display the existing values for the ANSI/ITU SCCP Conversion feature options by entering the rtrv-stpopts command.

   This is an example of the possible output.

   STP OPTIONS
   -----------------------
   CNVCGDA             no
   CNVCGDI             no
   CNVCGDN             no
   CNVCGDN24           no
   GTCNVDFLT           no

   Note:

   The rtrv-stpopts command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-stpopts command, refer to the rtrv-stpopts command description in the Commands Manual.

   If the CNVCGDA, CNVCGDI, CNVCGDN, CNVCGDN24, and GTCNVDFLT fields are not shown in the output of the rtrv-stpopts command, perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enable the ANSI/ITU SCCP Conversion feature. After the ANSI/ITU SCCP Conversion feature has been enabled, the values for these options will be no.

   Note:

   The ANSI/ITU SCCP Conversion feature can only be permanently enabled.
2. Change the ANSI/ITU SCCP Conversion feature options by entering the chg-stpopts command with at least one of these parameters.
   • :on=cnvcgda - if the current value is no
   • :on=cnvcgdi - if the current value is no
   • :on=cnvcgdn - if the current value is no
   • :on=cnvcgdn24 - if the current value is no
   • :on=gtcnvdflt - if the current value is no
   • :off=cnvcgda - if the current value is yes
   • :off=cnvcgdi - if the current value is yes
   • :off=cnvcgdn - if the current value is yes
   • :off=cnvcgdn24 - if the current value is yes
   • :off=gtcnvdflt - if the current value is yes

   For this example, enter this command.

   chg-stpopts:on=cnvcgdi:on=gtcnvdflt

   When this command has successfully completed, this message should appear.

   CHG-STPOPTS: MASP A - COMPLTD

3. Verify the changes using the rtrv-stpopts command.

   This is an example of the possible output.

   STP OPTIONS
   -----------------------
   CNVCGDA             no
   CNVCGDI            yes
   CNVCGDN             no
   CNVCGDN24           no
   GTCNVDFLT          yes

   Note:

   The rtrv-stpopts command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-stpopts command, refer to the rtrv-stpopts command description in Commands Manual.
4. 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.
