Removing a Linkset Containing SS7 Signaling Links

This procedure is used to remove a linkset containing SS7 signaling links from the database using the dlt-ls command.

The dlt-ls command has only one parameter, lsn, which is the name of the linkset to be removed from the database.

The linkset to be removed must exist in the database.

To remove a linkset, all links associated with the linkset must be removed.

The linkset to be removed cannot be referenced by a routeset.

If the Flexible Linkset Optional Based Routing feature is enabled and turned on, and the linkset is referenced by a GTT selector, the linkset cannot be removed.

To remove an IPGWx linkset, a linkset containing signaling links assigned to cards running either the SS7IPGW or IPGWI applications, the IPGWx linkset cannot be the mate of another IPGWx linkset.

A proxy linkset whose APC is assigned to more than one proxy linkset cannot be removed if the linkset contains the proxy point code (shown in the PPCA/PPCI/PPCN/PPCN24 field in the rtrv-ls:apc/apca/apci/apcn/apcn24=<APC of the linkset> output) that is also assigned to the APC of the linkset. The proxy point code assigned to the APC of the linkset is shown in the rtrv-dstn:dpc/dpca/dpci/dpcn/dpcn24=<APC of the linkset> output. The linksets that do not contain the proxy point code that is assigned to the APC of the linkset must be removed before the linkset containing proxy point code that is assigned to the APC of the linkset can be removed.

Canceling the RTRV-LS Command

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

Press the F9 function key on the keyboard at the terminal where the rtrv-ls command was entered.
Enter the canc-cmd without the trm parameter at the terminal where the rtrv-ls command was entered.
Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-ls command was entered, from another terminal other that the terminal where the rtrv-ls 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.

Display the current linkset configuration using the rtrv-ls command. This is an example of the possible output.

If the linkset being removed is a proxy linkset (LST=PRX), and more than one linkset is shown in the rtrv-ls output that contains the APC of the linkset being removed, continue the procedure with 2.

If the linkset being removed is not a proxy linkset, or is a proxy linkset whose APC is not used by more than one linkset, continue the procedure with 4.

Display the linksets that contain the APC of the linkset being removed by entering the rtrv-ls command with the APC of the linkset. For this example, enter this command.

A proxy linkset whose APC is assigned to more than one proxy linkset cannot be removed if the linkset contains the proxy point code (shown in the PPCA/PPCI/PPCN/PPCN24 field in 2) that is also assigned to the APC of the linkset (shown in 3). The linksets that do not contain the proxy point code that is assigned to the APC of the linkset must be removed before the linkset containing proxy point code that is assigned to the APC of the linkset can be removed.

Display the signaling links in that linkset being removed using the rtrv-ls command, specifying the linkset name of the linkset you wish to remove from the database. For this example, enter these commands.

rtrv-ls:lsn=ls1

If any signaling links in the linkset are the last signaling link on a card, the card must be placed out of service before that signaling link can be removed. Verify this by entering the rtrv-slk command and specifying each of the card locations shown in the output of 4. Do not specify the link parameter. For this example, enter these commands.

If the output of 8 shows that any of the signaling links in the specified linkset are the last signaling links on the card, place that card out of service by using the rmv-card command, specifying the card location to be taken out of service. For this example, enter these commands.
rmv-card:loc=1205

When this command has successfully completed, this message should appear.

If the linkset being removed in this procedure is not assigned to a route exception table entry, no entries are displayed in the rtrv-rtx output, but a summary of the point code quanties is displayed.

If the name of the linkset being removed in this procedure shown in the LSN column in this step, perform one of these procedures:

Change the name of the linkset in the entries displayed in this step by performing the Changing a Route Exception Entry procedure.
Remove all the entries displayed in this step by performing the Removing a Route Exception Entry procedure.

If the Flexible Linkset Optional Based Routing feature is enabled and turned on, and the linkset if referenced by any GTT selectors, the linkset cannot be removed.

If the linkset contains the entries fcd, fcg, fcdfcg, or fcgfcd in the GTTMODE column of the rtrv-ls output in 4, the Flexible Linkset Optional Based Routing feature is enabled and turned on. Continue the procedure with 17.

If the linkset does not contain the entries fcd, fcg, fcdfcg, or fcgfcd in the GTTMODE column of the rtrv-ls output in 4, continue the procedure with 16.

If GTT selectors are shown in the rtrv-gttsel output, perform the "Removing a GTT Selector" procedure in Database Administration - GTT User's Guide to remove all entries shown in this step. After the GTT selectors have been removed, continue the procedure with 18.

If GTT selectors are not shown in the rtrv-gttsel output, continue the procedure with 18.

Remove the linkset using the dlt-ls command. For this example, enter these commands.
dlt-ls:lsn=ls1

dlt-ls:lsn=lsgw1103

dlt-ls:lsn=lsn151

When each of these commands have successfully completed, this message should appear.

Verify the changes using the rtrv-ls command with the linkset name used in 18.
For this example, enter these commands.

rtrv-ls:lsn=lsn1

rtrv-ls:lsn=lsgw1103

rtrv-ls:lsn=lsn151

If the removal of the linkset was successful, the following message is displayed.
```

No matching entry found.

```
Continue the procedure with 20 if the linkset that was removed in has any of these attributes.
- The linkset was not a proxy linkset.
- The linkset was a proxy linkset whose APC was assigned to only the proxy linkset that was removed in 18.
- The linkset was a proxy linkset and:
  - The APC of this linkset is assigned to more than one linkset.
  - The linkset did not contain the proxy point code that was assigned to the APC of the linkset.
  - The linkset that contains the proxy point code that is assigned to the APC of the linkset will not be removed from the database.
If you wish to remove the proxy linkset that contains the proxy point code that is also assigned to the APC of the linkset, and the database contains other linksets that are assigned to this APC, these other linksets must be removed before the proxy linkset that contains the proxy point code that is also assigned to the APC of the linkset can be removed. Repeat this procedure from 2 to remove these linksets. After these linksets have been removed, perform this procedure again from 2 to remove the proxy linkset that contains the proxy point code that is also assigned to the APC of the linkset.

Back up the new changes using the chg-db:action=backup:dest=fixed command. These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.
