Removing a Loopset

This procedure is used to remove an entire loopset from the database or a specific point code in a loopset using the dlt-loopset command.

The dlt-loopset command uses these parameter.

:name - The name of the loopset being removed, shown in the rtrv-loopset output.

:force – This parameter has two values, yes or no. The value yes allows the point code in the loopset to be removed if the loopset is assigned to entries in either the rtrv-gtt or rtrv-gta outputs. The value no requires that any references to the loopset must be removed from the GTT or GTA entries before the loopset or the point code in the loopset can be removed. Perform one of these procedures to remove the reference to the loopset, depending on whether or not the EGTT feature is on. The status of the EGTT feature is shown in the rtrv-feat command output.

If the EGTT feature is not on – Enter the rtrv-gtt command to verify the loopset references. Perform the Changing a Global Title Translation procedure and change the loopset reference to NONE or to another loopset name, or remove the global title translation by performing the Removing a Global Title Translation procedure.
If the EGTT feature is on – Enter the rtrv-gta command to verify the loopset references. Perform Changing Global Title Address Information and change the loopset reference to NONE or to another loopset name, or remove the entry by performing the Removing Global Title Address Information procedure.

:pcl/pcla/pcli/pcln/pcln24 – The point code, either an ANSI point code (pcl/pcla), ITU-I or ITU-I spare point code (pcli), a 14-bit ITU-N or 14-bit ITU-N spare point code (pcln), or a 24-bit ITU-N (pcln24) point code, that is assigned to the loopset and shown in the rtrv-loopset output.

If the dlt-loopset command is specified with the name and pcl/pcla/pcli/ pcln/pcln24 parameter, the specified point code is removed from the loopset.

If the dlt-loopset command is specified with the name parameter and without the pcl/pcla/pcli/pcln/pcln24 parameter, the entire loopset is removed from the database.

Display the loopsets in the database by entering this command. This is an example of the possible output
rtrv-loopset:num=1000:force=yes

Note:
If the rtrv-loopsetcommand is entered with no other parameters specified, a maximum of 50 entries are displayed. To display more than 50 entries, the force=yes parameter must be specified with the rtrv-loopset command and the num parameter value must be greater than 50. Since there can be a maximum of 1000 loopsets in the database, to display all the loopsets in the database, the force=yes and num=1000 parameters must be specified with the rtrv-loopsetcommand.

This is an example of the possible output.

If error message E4565 is displayed or if no loopsets are displayed, this procedure cannot be performed.

Note:
If the force=yes parameter will be specified with the dlt-loopsetcommand, only a specific point code can be removed from the loopset. Skip steps 2 through 6 and go to step 7.
Verify whether or not the EGTT feature is turned on by entering the rtrv-feat command. If the EGTT featured is turned on, the EGTT 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 know about all the fields displayed by the rtrv-feat command, refer to the rtrv-feat command description in Commands User's Guide.

Note:
If the EGTT feature is not turned on, skip steps 3 and step 4, and go to step 5.

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

If any of the displayed entries reference the loopset being removed, for those entries, perform Changing Global Title Address Information and change the loopset reference to NONE or to another loopset name, or remove the entry by performing the Removing Global Title Address Information procedure.

If the displayed entries do not reference the loopset being removed, repeat this step with the other GTT set names displayed in step 3.

When all the GTT set names have been displayed and all applicable global title translation entries have been changed or removed in this step, go to step 7.

Display the translation types in the database using the rtrv-tt command. This is an example of the possible output.

If any of the displayed entries reference the loopset being removed, for those entries, perform the Changing a Global Title Translation procedure and change the loopset reference to NONE or to another loopset name, or remove the global title translation by performing the Removing a Global Title Translation procedure.

If the displayed entries do not reference the loopset being removed, repeat this step with the other translation types displayed in step 5.

When all the translation types have been displayed and all applicable global title translation entries have been changed or removed in this step, go to step 7.
If an entire loopset is being removed from the database, specify the dlt-loopset command with the name of the loopset you wish to remove.
If a point code value is being removed from the loopset, specify the dlt-loopset command with the name of the loopset and the point code value you wish to remove.

For this example, enter this command to remove the entire loopset.

dlt-loopset:name=rtp1

This message should appear.

Note:
If the loopset containing the point code being removed in this step is referenced by an entry shown in either the rtrv-gtt or rtrv-gta outputs, and those entries have not been removed or the loopset assignment for these entries has not been changed, the force=yes parameter must be specified with the dlt-loopset command.

If you wish to remove other point codes from the loopset, repeat this step. When you have finished removing the point codes from the loopset, go to step 8.
Verify the changes using the rtrv-loopset command with the name of the loopset specified in step 7. For this example, enter this command.
rtrv-loopset:name=rtp1

The following message should appear if you have deleted specific point codes in the loopset.

If a point code value was removed from a loopset in step 7 and the force=yes was not used in step 7, and you wish to assign this loopset to the GTT or GTA entries that were removed or changed in steps 4 or 6, go to step 10.

If any of the following actions were performed in step 7, this procedure is finished. Do not perform step 10.
- An entire loopset was removed in step 7.
- A point code value was removed from a loopset with the force=yes parameter in step 7.
- A point code value was removed from a loopset in step 7, the force=yes was not used in step 7, and you do not wish to assign this loopset to the GTT or GTA entries that were removed or changed in steps 4 or 6.
Assign the loopset specified in step 7 to the GTT or GTA entries that were removed or changed in steps 4 or 6.
If the EGTT feature is not on, perform one of these procedures:
- Adding a Global Title Translation procedure if the GTT entry was removed from the database in step 6.
- Changing a Global Title Translation procedure if the GTT entry was changed in step 6.
If the EGTT is on, perform one of these procedures:
- Adding Global Title Address Information procedure if the GTA entry was removed from the database in step 4.
- Changing a GTT Selector procedure if the GTA entry was changed in step 4.
