Removing a Translation Type

This procedure is used to remove a translation type from the database using the dlt-tt command.

The dlt-tt command uses these parameters.

:type/typea/typei/typeis/typen/typens/typen24 – The translation type and network type of that translation type. The translation type indicates which global title translation table is to be used to determine the routing to a particular service database.

• :type or :typea – an ANSI network
• :typei – an ITU international network
• :typeis – an ITU international spare network
• :typen – a 14-bit ITU national network.
• :typens – a 14-bit ITU national spare network.
• :typen24 – a 24-bit ITU national network.

:ttn – The name of the global title translation type

:alias – The alias of the global title translation type

The examples in this procedure are used to remove the translation type 3 from the database.

The translation type, translation type name, or alias specified with the dlt-tt command must be shown in the rtrv-tt output, and must be assigned to the specified translation type

The translation type cannot be removed if the global title translation tables reference the translation type. Verify that the global title translation tables do not reference the translation type using the rtrv-gtt command.

If the rtrv-gtt command shows references to the translation type to be removed, go to the Removing a Global Title Translation procedure and remove the global title translation data associated with the translation type.

If the translation type is referenced by an alias, all aliases to the translation type must be removed first. To remove the alias, the alias and translation type must be specified in the dlt-tt command.

This procedure can be performed if the EGTT feature is turned on. If the EGTT feature is turned on, these rules apply.

1. The dlt-tt command removes the GTT selectors defined by the translation type that is specified with the dlt-tt command. if the ttn and tt parameters are specified with the dlt-tt command, the GTT selectors that are associated with the GTT set name that is defined by the ttn parameter value are removed. When the last GTT selector that is associated with a GTT set is removed with the dlt-tt command, the GTT set is removed. The GTT selectors are shown in the rtrv-gttsel output and the GTT sets are shown in the rtrv-gttset output.
2. The GTT set that is associated with GTT selectors that are being removed can not be referenced by any GTA entry, shown in the rtrv-gta output, and cannot be referenced in any other GTT selector.
3. The GTT selectors that can be removed using the dlt-tt command can be associated only with CDGTA GTT sets.
4. To remove an ITU GTT selector is removed using the dlt-tt command, there must be entries in the database that contain the global title indicator values 2 and 4, along with the specified translation type value, and the translation type name value (this is the GTT set name) if the ttn parameter is specified. To remove a GTT selector using the dlt-tt command, these columns of the GTT selector entries must contain these values.
   • NP - dflt - for ITU GTT selectors only. ANSI GTT selectors can only contain dashes in this column.
   • NAI - dflt - for ITU GTT selectors only. ANSI GTT selectors can only contain dashes in this column.
   • CGSSN - dashes
   • SELID - none
   • LSN - any

Canceling the RTRV-GTT Command

Because the rtrv-gtt command used in this procedure can output information for a long period of time, the rtrv-gtt command can be canceled and the output to the terminal stopped. There are three ways that the rtrv-gtt command can be canceled.

• Press the F9 function key on the keyboard at the terminal where the rtrv-gtt command was entered.
• Enter the canc-cmd without the trm parameter at the terminal where the rtrv-gtt command was entered.
• Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-gtt command was entered, from another terminal other that the terminal where the rtrv-gtt command was entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

1. Verify that the GTT feature is on, by entering the rtrv-feat command. If the GTT feature is on, the GTT 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, refer to the rtrv-feat command description in Commands User's Guide.

   If the GTT feature is off, this procedure cannot be performed.

   If the GTT feature is on, continue the procedure with 2.

2. Display the translation types in the database using the rtrv-tt command.

   This is an example of the possible output.

   If the translation type that is being removed contains an alias translation type and the alias translation type is being removed, continue the procedure with 8.

   If the translation type does not contain an alias translation type or if an alias translation type is not being removed, continue the procedure by performing one of these steps.

   • If the EGTT feature is not on, continue the procedure with 7.
   • If the EGTT feature is on, continue the procedure with 3.
3. Display the GTT set by entering the rtrv-gttset command with the TTN value that is assigned to the translation type for the gttsn parameter value.

   For this example, enter this command.

   rtrv-gttset:gttsn=d700

   This is an example of the possible output.

   If the NETDOM value of the GTT set is CROSS, the translation type cannot be removed with this procedure. Perform the Removing a GTT Selector procedure to remove the translation type.

   If the NETDOM value is ANSI or ITU, continue the procedure by performing one of these steps.

   • If the SETTYPE column is not shown in the rtrv-gttset output, continue the procedure with 5.
   • If the SETTYPE column is shown in the rtrv-gttset output, continue the procedure with 4.
4. Display the features that are enabled by entering the rtrv-ctrl-feat command.

   The following is an example of the possible output.

   rlghncxa03w 10-07-28 21:15:37 GMT EAGLE5 42.0.0
   The following features have been permanently enabled:

   Zero entries found.
   
   The following features have expired temporary keys:
   
   Feature Name              Partnum
   Zero entries found.

5. Display the GTT selectors in the database by entering the rtrv-gttsel command with the tt parameter and with one of these parameters.
   • gttsn
   • cdgtasn
   • cggtasn
   • cdgttsn
   • cggttsn

   The value that must be specified for the parameter in the previous list that will be specified with the rtrv-gttsel command is the GTTSN value specified in 3. The parameter that must be specified for the TTN value is dependent on the feature that is enabled as shown in Table 3-2. The features that are enabled are shown in 4.

   Table 3-2 RTRV-GTTSEL GTT Set Name Parameters

   Feature that is Enabled	Parameter that must be Specified for the TTN Value
   No feature is enabled, the SETTYPE column is not shown in the rtrv-gttset output	gttsn
   Origin Based SCCP Routing	cdgtasn, cggtasn
   Flexible Linkset Optional Based Routing, shown as Flex Lset Optnl Based Rtg in the rtrv-ctrl-feat output	cdgttsn, cggttsn

   If the Origin Based SCCP Routing or Flexible Linkset Optional Based Routing features are enabled, enter the rtrv-gttsel command with each parameter shown in Table 3-2.

   For this example, enter this command.

   rtrv-gttsel:gttsn=d700:tt=3

   This is an example of the possible output.

   If no entries are displayed, continue the procedure with 6.

   If entries are displayed, continue the procedure by performing one of these steps.

   • If any of the entries shown in the rtrv-gttsel output do not have the default values for the advanced GTT parameters, or if a GTT selector entry with the TTN value was removed with the dlt-gttsel command, the remainder of this procedure cannot be performed. Perform the Removing a GTT Selector procedure to remove the entry.
   • If all of the entries shown in the rtrv-gttsel output have the default values for the advanced GTT parameters, and none of the GTT selector entries with the TTN value were removed with the dlt-gttsel command, continue the procedure with 6.

   The default values for the advanced GTT parameters are shown in this list.

   • NP - dflt - for ITU GTT selectors only. ANSI GTT selectors can only contain dashes in this column.
   • NAI - dflt - for ITU GTT selectors only. ANSI GTT selectors can only contain dashes in this column.
   • CGSSN - dashes
   • SELID - none
   • LSN - any
6. Display the GTA entries that reference the TTN value of the translation type by entering the rtrv-gta command with the TTN value for the gttsn parameter value.

   For this example, enter this command.

   rtrv-gta:gttsn=d700

   This is an example of the possible output.
