Using the MULTGC Parameter when Changing the Attributes of a Linkset

This procedure is used to verify that the following items are configured in the database.

The ITU Duplicate Point Code feature is turned on.
If the multgc parameter value is being changed to no, and the linkset contains more than one 14-bit ITU-N secondary adjacent point code, all but one of these secondary adjacent point codes must be removed from the linkset.

The multgc parameter only applies to linksets whose adjacent point codes are either ITU international point codes or 14-bit ITU national point codes. All the signaling links in this linkset must be assigned to cards running the IPLIMI or IPGWI applications, or the linkset must be an IPSG M2PA linkset. The linkset cannot be a proxy linkset.

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 the Commands User's Guide.

Display the current linkset configuration using the rtrv-ls command.

This is an example of the possible output.

The multgc parameter can be specified only for linksets with either ITU-I or 14-bit ITU-N APCs. The linkset can contain only signaling links assigned to the IPLIMI or IPGWI applications, or must be an IPSG M2PA linkset. The linkset cannot be a proxy linkset; a linkset whose linkset type is PRX (lst=prx). If the shown in this step does not meet this criteria, the multgc parameter value for this linkset cannot be changed. This procedure is finished.
If the linkset does meet the criteria described in the previous paragraph, continue the procedure by performing one of these steps.
- To change the multgc parameter value, the ITU Duplicate Point Code feature must be turned on. If the MULTGC column is shown in the rtrv-ls output in this step, the ITU Duplicate Point Code feature is turned on. If the MULTGC column is not shown in the rtrv-ls output in this step, continue the procedure with 3.
- If the MULTGC column is shown in the rtrv-ls output in this step, and the multgc parameter value will be changed to no, continue the procedure with 5.
- If the MULTGC column is shown in the rtrv-ls output in this step, and the multgc parameter value will be changed to yes, this procedure is finished.
To specify the multgc=yes parameter with the chg-ls command, the ITU Duplicate Point Code feature must be on.

For the ITUDuplicate Point Codefeature to be on, the Multiple Point Codefeature must be on. Enter the rtrv-featcommand to verify that either of these features are on. The entry MPC = onin the rtrv-featcommand output shows that the Multiple Point Codefeature 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 Commands User's Guide.
Turn the ITU Duplicate Point Code feature on, and the Multiple Point Code feature if necessary, by entering one of these commands.
- To turn the ITU Duplicate Point Code feature on only.
  
  chg-feat:ituduppc=on
- To turn both the ITU Duplicate Point Code and Multiple Point Code features on.
  
  chg-feat:mpc=on:ituduppc=on
Note:
Once the ITU Duplicate Point Code and Multiple Point Code features are turned on with the chg-feat command, they cannot be turned off.
The ITU Duplicate Point Code and Multiple Point Code features must be purchased before you turn either of these features on with the chg-feat command. If you are not sure if you have purchased these features, contact your Oracle Sales Representative or Account Representative.

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

This procedure is finished.
If the multgc parameter value is changed to no, the linkset can contain only one secondary adjacent point code.

An ITU international linkset can contain only one 14-bit ITU national secondary adjacent point code. If the ITU international linkset contains more than one 14-bit ITU national secondary adjacent point code, all but one of these 14-bit ITU national secondary adjacent point codes must be removed from the linkset. An ITU national linkset can contain only one ITU international secondary adjacent point code. All 14-bit ITU-N secondary adjacent point codes must be removed from the linkset. All routes to these secondary adjacent point codes must be removed from the database before the secondary adjacent point codes can be removed.

Display the routes using the secondary adjacent point code being removed from the linkset with the rtrv-rte command, specifying the secondary adjacent point code being removed as the value of the dpc parameter.
For this example, enter these commands.

rtrv-rte:dpcn=11213-de

This is an example of the possible output.

If the secondary adjacent point code is assigned to a route, that route must be removed from the database. Perform Removing a Route to remove the route from the database.
Remove the secondary adjacent point codes specified in 5 from the linkset with the chg-ls command with the sapcn and the action=delete parameters.

For this example, enter these commands.
chg-ls:lsn=lsn5:sapcn=11213-de:action=delete

chg-ls:lsn=lsn5:sapcn=12114-fr:action=delete
