Removing a Secondary Point Code

This procedure is used to remove a secondary point code from the database using the dlt-spc command.

The dlt-spc command uses only one parameter: spc/spca/spci/spcn/spcn24 – the secondary point code.

Note:

See Point Code Formats for a definition of the point code types that are used on the EAGLE and for a definition of the different formats that can be used for ITU national point codes.

The secondary point code being removed from the database must be in the database, but cannot be referenced by any destination point codes or by any linksets. Entering the rtrv-dstn command with either the spca, spci, spcn, or spcn24, depending on the point code type of the secondary point code being removed from the database, shows the destination point codes that are referencing the secondary point code being removed from the database.

Entering the rtrv-ls command with either the spca, spci, spcn, or spcn24, depending on the point code type of the secondary point code being removed from the database, shows the linksets that are referencing the secondary point code being removed from the database.

For the example in this procedure, secondary point code 010-100-010 is being removed from the database.

Canceling the RTRV-DSTN Command

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

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

Display the secondary point codes in the database, using the rtrv-spc command. This is an example of the possible output.

Display the destination point codes that reference the secondary point code being removed from the database using the rtrv-dstn command with either the spca, spci, or spcn parameters.
For this example, enter this command.

rtrv-dstn:spca=010-100-010

This is an example of the possible output.

- If no DPCs are shown in this step, skip step 3 and go to step 4.
- If DPCs are shown in this step, continue the procedure with step 3.
Remove the reference to the secondary point code using the chg-dstn command and specifying the destination point codes shown in step 2 with either the dpca, dpci, or dpcn parameters, and with either the spca=none, spci=none, or spcn=none parameters, depending on the type of point codes being used. For this example, enter these commands.
chg-dstn:dpca=240-012-004:spca=none

chg-dstn:dpca=240-012-005:spca=none

When this command has successfully completed, and the cluster routing and management diversity feature is turned off (CRMD = off in the rtrv-feat command output), this message should appear.

After this step has been performed,.skip steps 4 and 5 and go to step 6.

Display the status of the Multiple Linksets to Single APC feature by entering this command.

rtrv-ctrl-feat:partnum=893019701

This is an example of the possible output.

If the Multiple Linksets to Single APC feature is enabled and turned on, continue the procedure with step 5.

If the Multiple Linksets to Single APC feature is not enabled or turned on, skip step 5 and go to step 6.

Display the linksets that reference the secondary point code that is being removed by entering the rtrv-ls command with the secondary point code value.
For this example, enter this command.

rtrv-ls:spca=010-100-010

This is an example of the possible output.

If linksets are shown in this step, these linksets must be removed before the secondary point code can be removed. Perform the Removing a Linkset Containing SS7 Signaling Links procedure to remove the linksets. After the linksets have been removed, continue the procedure with step 6.

If no linksets are shown in this step, continue the procedure with step 6.
Remove the secondary point code, using the dlt-spc command. For this example, enter this command.
dlt-spc:spca=010-100-010

Verify the changes using the rtrv-spc command specifying the secondary point code specified in step 6.
For this example, enter this command.
