Adding a GTT Set

Use this procedure to add a global title translation (GTT) set to the database using the ent-gttset command. Subsequent global title selector (gttsel) or global title address (gta) commands may then be entered.

The ent-gttset command uses these parameters.

:gttsn – The GTT set name consisting of one alphabetic character and up to eight alphanumeric characters.

:netdom – The network domain of the global title translation set, either ANSI, ITU, or CROSS. The network domain CROSS can be specified only if the ANSI/ITU SCCP Conversion feature, part number 893012001, is enabled. The CROSS GTT set can be assigned to either an ANSI or ITU GTT selector.

Note:

The ITU domain does not distinguish between ITU-N (either ITU-N or ITU-N24) and ITU-I since the Enhanced Global Title Translation (EGTT) database does not yet distinguish ITU-National and ITU-International translations.

:ndgt – The number of digits contained in the global title translation.

:settype – The type of GTT set being added in this procedure shown in Table 4-1.

Table 4-1 GTT Set Types

SETTYPE Value	Feature Requirements
CDGTA, CGGTA, CGPC, CGSSN, or OPC	The Origin-Based SCCP Routing feature must be enabled.
CDSSN or DPC	The Flexible Linkset Optional Based Routing feature must be enabled and turned on.
OPCODE	The TCAP Opcode Based Routing feature must be enabled and turned on.

The Global Title Translation (GTT) and the Enhanced Global Title Translation (EGTT) features must be on before using this command. Use the rtrv-feat command to verify the settings. If the features are off, perform the Adding a Service Module procedure to turn these features on and to make sure that the correct hardware is installed to support these features.

Note:

Once the Global Title Translation (GTT) feature and the Enhanced Global Title Translation (EGTT) feature are turned on with the chg-feat command, they cannot be turned off.

The GTT feature and the EGTT feature must be purchased before you turn these features on. If you are not sure whether you have purchased the GTT feature and/or the EGTT feature, contact your Oracle Sales Representative or Account Representative.

The GTT set name (gttsn) may not already exist and must be specified with the domain. The GTT set table may not have more than 2000 entries.

If the Variable-length Global Title Translation Feature (VGTT) is on, shown by the entry VGTT = on in the rtrv-feat command output, or the Support for 16 GTT Lengths in VGTT feature is enabled and turned on, the ndgt parameter cannot be specified with the ent-gttset command. If the VGTT feature is on, a GTT set can contain a maximum of 10 different length global title addresses. If the Support for 16 GTT Lengths in VGTT feature is enabled and turned on, a GTT set can contain a maximum of 16 different length global title addresses. The length of the global title address is determined when the global title address is entered with the ent-gta command. For more information on the VGTT feature and the length of global title addresses, refer to the Variable-length Global Title Translation Feature section and the Adding Global Title Address Information procedure.

The VGTT functionality is supported only for CDPA GTT sets (settype=cdgta) and CGPA GTT sets (settype=cggta).

If GTT sets are shown in this step, or error message “E3557 Cmd Rej: EGTT must be ON before this command can be entered” is not displayed, continue the procedure with 2.

If error message is displayed, “E3557 Cmd Rej: EGTT must be ON before this command can be entered,” the EGTT feature is not on. Perform the Adding a Service Module procedure to turn the EGTT feature on and to make sure that the correct hardware is installed and provisioned. After the Adding a Service Module procedure has been performed, continue the procedure with 2.

To specify any of these parameters or values for the GTT set, the feature that corresponds to the parameter or value must be shown as enabled, and turned on if required, in the rtrv-ctrl-feat output.

Perform the procedure, shown in this list, that corresponds to the parameters and values that you wish to specify for the GTT set.

settype - one of these features shown in Table 4-4 must be enabled, and turned on if necessary. If the SETTYPE column is not shown in the rtrv-gttset output and you wish to use the settype parameter, one of the features shown in Table 4-4 must be enabled and turned on, if necessary. If the settype column is shown in the rtrv-gttset output in 1, the settype parameter must be specified with the ent-gttset command.

Table 4-4 SETTYPE Feature Requirements

SETTYPE Value	Feature Requirements	Procedure to Verify the Feature’s Status and to Enable, and Turn On the Feature
CDGTA, CGGTA, CDSSN, CGPC, or OPC	Origin-Based SCCP Routing feature must be enabled.	Activating the Origin-Based SCCP Routing Feature – See the Note.
CDSSN or DPC	The Flexible Link set Optional Based Routing feature must be enabled and turned on.	Activating the Flexible Linkset Optional Based Routing Feature – See the Note.
OPCODE	TCAP Opcode Based Routing feature must be enabled and turned on.	Activating the TCAP Opcode Based Routing Feature – See the Note.
Note: If the desired SETTYPE value is shown in the `rtrv-gttset` output for any GTT set, the required feature is enabled, and turned on if required. The procedure for activating the feature does not need to be performed.

netdom=cross - the ANSI/ITUANSI/ITU SCCP Conversion feature must be enabled. Perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to verify the status of the ANSI/ITU SCCP Conversion feature and to enable the ANSI/ITU SCCP Conversion feature if necessary. If the CROSS value is shown in the NETDOM column of the rtrv-gttset output for any GTT set, the Activating the ANSI/ITU SCCP Conversion Feature procedure does not need to be performed.
The Support for 16 GTT Lengths in VGTT feature must be enabled and turned on, if the GTT set will contain 11 to 16 different GTA lengths. Perform the Activating the Support for 16 GTT Lengths in VGTT Feature procedure to verify the status of the Support for 16 GTT Lengths in VGTT feature and to enable and turn on the Support for 16 GTT Lengths in VGTT feature if necessary. If GTT sets containing 11 to 16 different GTA lengths are shown in the rtrv-gttset, the Activating the Support for 16 GTT Lengths in VGTT Feature procedure does not need to be performed.

Continue the procedure by performing one of these steps.

If the Support for 16 GTT Lengths in VGTT feature is enabled and turned on or the Activating the Support for 16 GTT Lengths in VGTT Feature procedure was performed in this step, continue the procedure with 5.
If the Support for 16 GTT Lengths in VGTT feature is not enabled or turned on and the Activating the Support for 16 GTT Lengths in VGTT Feature procedure was not performed in this step, continue the procedure by performing one of these steps.
- If the GTT set will contain two to 10 different GTA lengths, the VGTT feature must be turned on. if GTA sets containing two to 10 different GTA lengths are shown in the rtrv-gttset output, the VGTT feature is turned on. Continue the procedure with 5.
- If the GTT set will contain two to 10 different GTA lengths, and no GTT sets are shown in the rtrv-gttset output that contain two to 10 different GTA lengths, continue the procedure with 3.
- If the GTT set will contain GTAs that have only one length, continue the procedure with 5.

Verify that the VGTT feature is on by entering the rtrv-feat command. If the VGTT feature is on, the VGTT field should be set to on.
Note:
The rtrv-feat command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-feat command, see the rtrv-feat command description in Commands User's Guide.
Continue the procedure by performing one of these steps.
- If the VGTT feature is on, continue the procedure with 5.
- If the VGTT feature is off, continue the procedure with Oracle.
Turn the VGTT feature on by entering this command.
chg-feat:vgtt=on

Note:
Once the Variable-length Global Title Translation (VGTT) feature is turned on with the chg-feat command, it cannot be turned off.
The VGTT feature must be purchased before you turn this feature on. If you are not sure whether you have purchased the VGTT feature, contact your Oracle Sales Representative or Account Representative.

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