Changing a GTT Set

Use this procedure to change the number of digits assigned to a global title translation (GTT) set, change the network domain of the GTT set to CROSS, or change the GTT set name using the chg-gttset command.

The chg-gttset command uses these parameters:

:gttsn – The GTT set name. The GTT set name (gttsn) specifies the GTT set being changed and must be shown in the rtrv-gttset output.

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

:netdom=cross – The CROSS network domain of the global title translation set. The network domain CROSS can be specified only if the ANSI/ITU SCCP Conversion feature, part number 893012001, is enabled, and if the GTT set is a CDGTA GTT set. If the SETTYPE column is not shown in the rtrv-gttset output, all the GTT sets are CDGTA GTT sets. The CROSS GTT set can be assigned to either an ANSI or ITU GTT selector. For more information, refer to the ANSI/ITU SCCP Conversion Feature section.

:gttsetmeasrqd - GTTSET Measurement required. This parameter specifies whether to perform per GTTSET measurements.

:ndgt – The number of digits contained in the global title translation. The ndgt parameter cannot be specified:

If the Origin-Based SCCP Routing feature is enabled, the SETTYPE value of the GTT set is CGSSN, CGPC, or OPC.
If the Flexible Linkset Optional Based Routing feature is enabled and turned on, the SETTYPE value of the GTT set is CDSSN or DPC.
If the TCAP Opcode Based Routing feature is enabled and turned on, the SETTYPE value of the GTT set is OPCODE.
If GTAs are assigned to the GTT set. This can be verified with the rtrv-gta command and the GTT set name being changed in this procedure.
If the VGTT feature is on, shown by the entry VGTT = on in the rtrv-feat command output. 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, see the Variable-length Global Title Translation Feature section and the Adding Global Title Address Information procedure.

If the Variable-length Global Title Translation Feature (VGTT) is on, the NDGT field of the rtrv-gttset command shows the different lengths of global title addresses assigned to a GTT set name, as shown in the following example.
```

imsi      itu     15
abcd1234  itu     12

GTT-SET table is (5 of 2000) 1% full.
```
In this example of the rtrv-gttset command output, the GTT set lidb contains three different length global title addresses; global title addresses containing three digits, seven digits, and 10 digits.

Caution:
If the VGTT feature is on and the ANSI/ITU SCCP Conversion feature is not enabled, this procedure cannot be performed.

:sxudt - Segmented XUDT. This parameter specifies whether TOBR will support the processing of segmented XUDT message.

Note:

The SXUDT parameter must be specified with the OPCODE GTT set type only.

Display the existing GTT sets in the database by entering the rtrv-gttset command.
This is an example of the possible output.

```
If the SETTYPE column is not shown in the rtrv-gttset output, all the GTT sets are CDGTA GTT sets.

If the SETTYPE column is shown in the rtrv-gttset output, and the SETTYPE value for the GTT set is CGPC, CGSSN, OPC, CDSSN, OPCODE, DPC, only the name of the GTT set can be changed.
If any GTT sets contain multiple entries in the NDGT column, the VGTT feature is on. The ndgt parameter cannot be specified with the chg-gttset command. The NETDOM value can be changed to CROSS only for a CDGTA GTT set. The name of the GTT set can be changed for any type of GTT set. Continue the procedure by performing one of these steps.
- If you do not wish to change the NETDOM value to CROSS for a CDGTA GTT set, or if you wish to only change the name of any type of GTT set, continue the procedure with 5.
- If you wish to change the NETDOM value to CROSS for a CDGTA GTT set, continue this procedure by performing one of these steps.
  - If any CDGTA GTT sets contain the value CROSS in the NETDOM column, continue the procedure with 5.
  - If the value CROSS does not appear in the NETDOM column for all the CDGTA GTT sets, continue the procedure with 3.
If all the GTT sets contain only one entry in the NDGT column, continue the procedure with 2.
Verify whether or not either the VGTT feature is on by entering the rtrv-feat command.
The entry VGTT = on is shown if the VGTT feature is 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 the Commands Manual.

If the VGTT feature is on, the ndgt parameter cannot be specified with the chg-gttset command.
If the VGTT feature is off, the ndgt parameter value can be changed under these conditions.
- If the SETTYPE column is not shown in the rtrv-gttset output in 1.
- If the SETTYPE column is shown in the rtrv-gttset output and the SETTYPE value for the GTT set is CDGTA or CGGTA.
If the NDGT value cannot be changed or you do not wish to change the NDGT value, the only action that can be performed on a GTT set is to change the NETDOM value to CROSS for a CDGTA GTT set. If you do not wish to change the NETDOM value to CROSS for a CDGTA GTT set, this procedure cannot be performed. If you wish to change the NETDOM value to CROSS for a CDGTA GTT set, continue the procedure by performing one of these steps.
- If any CDGTA GTT sets contain the value CROSS in the NETDOM column, continue the procedure by performing one of these steps.
  - If the ndgt parameter value will be changed, continue the procedure with 4.
  - If the ndgt parameter value will not be changed, continue the procedure with 5.
- If the value CROSS does not appear in the NETDOM column for all CDGTA GTT sets, continue the procedure with 3.
If you wish to change the ndgt parameter value and do not wish to change the NETDOM value to CROSS, continue the procedure with 4.
Display the status of the ANSI/ITU SCCP Conversion feature by entering this command.
rtrv-ctrl-feat:partnum=893012001

The following is an example of the possible output.
```
rlghncxa03w 07-05-28 21:15:37 GMT EAGLE5 37.0.0
The following features have been permanently enabled:

Feature Name              Partnum    Status  Quantity

Zero entries found.

The following features have expired temporary keys:

Feature Name              Partnum
Zero entries found.
```
If the ANSI/ITU SCCP Conversion feature is enabled, continue the procedure by performing one of these steps.
- If the ndgt parameter value will be changed, continue the procedure with 4.
- If the ndgt parameter value will not be changed, continue the procedure with 5.
If the ANSI/ITU SCCP Conversion feature is not enabled, the netdom=cross parameter cannot be specified with the chg-gttset command. If the ANSI/ITU SCCP Conversion feature is not enabled and the VGTT feature is on, this procedure cannot be performed.

If the ANSI/ITU SCCP Conversion feature is not enabled, perform the Activating the ANSI/ITU SCCP Conversion Feature procedure to enable the ANSI/ITU SCCP Conversion feature. After the ANSI/ITU SCCP Conversion is enabled, continue the procedure with 4.

Verify that no global title address information references the GTT set name being changed in this procedure.

Use the rtrv-gta command with the gttsn parameter specifying the GTT set name being removed from the database. If the num parameter is specified with the rtrv-gta command, and the value of the num parameter is greater than 1000, the force=yes parameter must be specified with the rtrv-gta command. For this example, enter this command.

rtrv-gta:gttsn=imsi

This is an example of the possible output.

If no global title address entries are shown in the rtrv-gta output, continue the procedure with 5.

If global title address entries are shown in the rtrv-gta output, perform Removing Global Title Address Information to remove any global title address entries that are shown in the rtrv-gta command output. After the global title address entries have been removed, continue the procedure with 5.

Change the GTT set using the chg-gttset command.
For this example, enter this command.

chg-gttset:gttsn=imsi:ndgt=10:netdom=cross

The netdom=cross parameter can be specified only if the ANSI/ITU SCCP Conversion feature is enabled. If the SETTYPE column is shown in the rtrv-gttset output, the netdom=cross parameter can be specified only for a CDGTA GTT set.

The ndgt parameter can be specified only if the VGTT feature is off. If the SETTYPE column is shown in the rtrv-gttset output, the ndgt parameter can be specified only for a CDGTA or CGGTA GTT set.

The ngttsn value cannot be none.
