Changing the Group Code Assigned to a 14-Bit ITU National Point Code

This procedure is used to change the group code that is assigned to a 14-bit ITU national point code. The 14-bit ITU national point code to be changed must be in the database.

To change a group code assigned to a ITU national point code, a duplicate point code with the new group code must be configured in the database with a route, linkset, and signaling link to the new destination. Then the 14-bit ITU national point code with the old group code with its route can be removed from the database.

The chg-dstn command cannot be used to change the group code assigned to 14-bit ITU national point codes.

The examples in this procedure are used to remove the group code assigned to ITU national destination point code 7-9-10-1-aa to 7-9-10-1-de. The format of the 14-bit ITU national point codes used in these examples is 4-4-4-2.

Canceling the RTRV-DSTN and RTRV-RTE Commands

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

• Press the F9 function key on the keyboard at the terminal where the rtrv-dstn or rtrv-rte command was entered
• Enter the canc-cmd without the trm parameter at the terminal where the rtrv-dstn or rtrv-rte command was entered
• Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-dstn or rtrv-rte command was entered, from another terminal other than the terminal where the rtrv-dstn or rtrv-rte 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, refer to Commands User's Guide.

1. Display all the attributes of the 14-bit ITU national point code whose group code is being changed, using the rtrv-dstn command with the dpcn parameter.

   For this example, enter this command.

   rtrv-dstn:dpcn=7-9-10-1-aa

   This is an example of the possible output.

2. Display the route configuration of the 14-bit ITU national point code specified in 1, by entering the rtrv-rte command with the dpcn parameter.

   For this example, enter this command.

   rtrv-rte:dpcn=7-9-10-1-aa

   This is an example of the possible output.

3. Go to the Removing a Destination Point Code procedure and add the duplicate ITU national point code with the new group code.

   For this example, the new point code is 7-9-10-1-de.

4. Go to the Removing a Destination Point Code procedure and remove the 14-bit ITU national point code with the old group code, specified is 1 and 2.

   This procedure will also remove the route to the point code with the old group code, the linkset used by this route, and the signaling links in that linkset. Record the configuration of the signaling links in the linkset. This information will be used to restore these signaling links in 6.

   Note:

   If the DPC specified in 2 is not the adjacent point code of a linkset, shown in the APCN field of the rtrv-rte output, continue the procedure with 7.bof 7.
5. Perform the Adding an SS7 Linkset procedure to add a new linkset to the database containing the 14-bit ITU national point code with the new group code specified in 3 as the APC of the linkset.
6. Perform the Adding an SS7 Signaling Link procedure to dd the signaling links that were removed by the Removing a Destination Point Code procedure in step 4 and specifying the linkset name of the linkset that was added in 5.
7. If the DPC specified in 2 is the adjacent point code of a linkset and a new linkset was created in 5, then perform 7.a. If the DPC specified in 2 is not the adjacent point code of a linkset, then perform 7.b. Do not perform 7.a and 7.b.
   1. Perform one of the “Adding a Route” procedures in Chapter 3 to add the route to the 14-bit ITU national point code with the new group code specifying the name of the linkset created in step 5 and the 14-bit ITU national point code with the new group code from 3.
   2. Perform one of the “Adding a Route” procedures in Chapter 3 to add the route to the 14-bit ITU national point code with the new group code specifying the 14-bit ITU national point code with the new group code from 3.
8. 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.

   BACKUP (FIXED) : MASP A - Backup starts on active MASP.
   BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
   BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
   BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
