Removing an IPSG M3UA Signaling Link

This procedure is used to remove an IPSG M3UA signaling link from the database using the dlt-slk command. The dlt-slk command uses these parameters.

:loc – The card location of the IPSG card that the IPSG M3UA signaling link is assigned to.

:link – The signaling link on the card specified in the loc parameter.

:force – This parameter must be used to remove the last link in a linkset without having to remove all of the routes that referenced the linkset.

The IPSG M3UA signaling link cannot be removed if removing the IPSG M3UA signaling link will cause the number of IS-NR IPSG M3UA signaling links in the linkset to be less than the NUMSLKALW, NUMSLKRSTR, or NUMSLKPROH values shown in the rtrv-ls output. The NUMSLKALW, NUMSLKRSTR, and NUMSLKPROH values are defined as follows.

NUMSLKALW - specifies the number of IS-NR (in-service normal) signaling links in the IPSG M3UA linkset required to change the state of the linkset from the Restricted or Prohibited state to the Allowed state.
NUMSLKRSTR - specifies the number of signaling links in the IPSG M3UA linkset required to change the state of the linkset from the Allowed state to the Restricted state.
NUMSLKPROH - specifies the number of signaling links in the IPSG M3UA linkset required to change the state of the linkset from the Allowed or Restricted state to the Prohibited state.

For more information about the NUMSLKALW, NUMSLKRSTR, and NUMSLKPROH values, refer to the Configuring IPSG M3UA Linkset Options procedure.

If the NUMSLKALW, NUMSLKRSTR, and NUMSLKPROH values are 1 or 0, then the IPSG M3UA signaling link can be removed. The value 0 is shown in the rtrv-ls output as a number with an asterisk (*), for example, 2*.

Canceling the RTRV-SLK Command

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

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

rtrv-slk:type=ipsg

This is an example of the possible output.

The IPSG M3UA signaling link cannot be removed if removing the IPSG M3UA signaling link will cause the number of IS-NR IPSG M3UA signaling links in the linkset to be less than the NUMSLKALW, NUMSLKRSTR, andNUMSLKPROH values shown in the rtrv-ls output. If the NUMSLKALW, NUMSLKRSTR, andNUMSLKPROH values are 1 or 0, then the IPSG M3UA signaling link can be removed. The value 0 is shown in the rtrv-ls output as a number with an asterisk (*) is displayed in the rtrv-ls output, for example, 2*.

If you do not wish to change the NUMSLKALW, NUMSLKRSTR, or NUMSLKPROH values, this signaling link cannot be removed and the remainder of this procedure cannot be performed.

If you with to change the NUMSLKALW, NUMSLKRSTR, or NUMSLKPROH values, perform the Configuring IPSG M3UA Linkset Options procedure to change the required values. After the Configuring IPSG M3UA Linkset Options has been performed, continue the procedure with 4
Any in-service IP connections on the signaling link being removed in this procedure must be placed out of service.
Have the far-end node for the signaling link being removed place the M3UA associations in either the ASP-INACTIVE or ASP-DOWN state.
- If the OPEN or ALW values for the associations is YES, continue the procedure with 5.
- If the OPEN and ALW values for the associations is NO, continue the procedure with 6.
Change the value of the open and alw parameters to no by specifying the chg-assoc command with the open=no and alw=no parameters, as necessary. For this example, enter this command.
chg-assoc:aname=assoc11:open=no:alw=no

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

Command Completed.

Remove the signaling link from the EAGLE using the dlt-slk command. If there is only one signaling link in the linkset, the force=yes parameter must be specified to remove the signaling link.
In the example used in this procedure, the signaling link is the last signaling link in the linkset. Enter this command.

dlt-slk:loc=2207:link=a:force=yes

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