Removing a GTT Set

Use this procedure to remove a GTT Set from the database using the dlt-gttset command.

The dlt-gttset command uses this parameter.

:gttsn – The GTT set name.

The GTT set name (gttsn) must be specified and match an existing GTT set. Use the rtrv-gttset command to view the GTT set names.

The GTT set name cannot be removed from the database if the name is referenced by any of these entities.

GTT Selectors - Use the rtrv-gttsel:gttsn=<GTT set name> command to view the GTT selectors using the specified GTT set name. If any GTT selectors are assigned to this GTT set name, perform the procedure Removing a GTT Selector to remove the selector from the database.
GTA entries - Use the rtrv-gta:gttsn=<GTT set name> command to view the global title address information using the specified GTT set name. If any GTAs are assigned to this GTT set name, perform the procedure Removing Global Title Address Information to remove the global title address information from the database.
The GTT set name cannot be shown in the rtrv-gsmsmsopts or rtrv-is41smsopts output as the BPARTYGTTSN value. Perform the procedure Configuring the GSM MO SMS B-Party Routing Options or the procedure Configuring the IS-41 MO SMS B-Party Routing Options to remove the GTT set name as the BPARTYGTTSN value.
The GTT set name cannot be shown in the rtrv-gsmsmsopts output as the IS41SMSCGTTSN value. Perform the procedures in IS41 GSM Migration User's Guide to remove the GTT set name as the IS41SMSCGTTSN value.

The examples in this procedure are used to remove the GTT set name t800 from the database.

Display the existing GTT sets in the database by entering this command.
rtrv-gttset:refcnt=yes

This is an example of the possible output.

The SETTYPE column is not shown in the rtrv-gttset output if the Origin-Based SCCP Routing feature is not enabled or the Flexible Linkset Optional Based Routing or TCAP Opcode Based Routing features are not enabled or turned on.

If the Origin-Based SCCP Routing feature is not enabled, the values CGGTA, CGPC, CGSSN, and OPC are not shown in the rtrv-gttset output.

If the Flexible Linkset Optional Based Routing feature is not enabled and turned on, the values CDSSN or DPC are not shown in the rtrv-gttset output.

If the TCAP Opcode Based Routing feature is not enabled, the value OPCODE is not shown in the rtrv-gttset output.

If the reference count of the GTT set that is being removed is 0 (zero), continue the procedure with 7. The reference count of the GTT set shows the number of database entities that reference the GTT set. The reference count value is shown in the REFCNT column of the rtrv-gttset output.

If the reference count of the GTT set that is being removed is greater than 0 (zero), continue the procedure with 2.

Verify that no global title address information references the GTT set name being removed from the database.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=t800

This is an example of the possible output.

Display the GTT selectors in the database by entering the rtrv-gttsel command with the GTTSN value of the GTT set that is being removed.

To specify of the GTTSN value of the GTT set, the parameters shown in Table 4-5 must be specified with the rtrv-gttsel command. The parameters that can be specified are dependent on the features that are enabled, shown in 3.

Table 4-5 RTRV-GTTSEL Parameters

Feature that is Enabled	Parameter that must be Specified for the TTN Value
Neither the Origin Based SCCP Routing nor the Flexible Linkset Optional Based Routing, shown as `Flex Lset Optnl Based Rtg` in the `rtrv-ctrl-feat` output, is enabled.	`gttsn`
