Removing an SS7 LIM

This procedure is used to remove an SS7 LIM (link interface module) from the database using the dlt-card command. The card cannot be removed if it does not exist in the database.

No SS7 signaling links can be assigned to the card you wish to remove from the database.

Caution:

If the SS7 LIM is the last SS7 LIM in service, removing this card from the database will cause SS7 traffic to be lost and isolate the EAGLE from the network.

Note:

1. LIM-E1 or LIMCH cards for E1 signaling links are removed from the database using the procedures in Appendix A, "E1 Interface" in Database Administration - SS7 User's Guide.

2. LIM-T1 or LIMCH cards for T1 signaling links are removed from the database using the procedures in Appendix B, "T1 Interface" in Database Administration - SS7 User's Guide.

3. IP cards (DCMs used for IP links) are removed from the database using the procedures in Database Administration - IP7 User's Guide.

The examples in this procedure are used to remove the SS7 LIMs in card location 1201, 1311, and 1318.

Canceling the REPT-STAT-CARD Command

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

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

1. Display the cards in the database using the rtrv-card command.

   This is an example of the possible output.

2. An SS7LIM is identified by the entries SS7ANSI, CCS7ITU, or ATMANSI in the APPL field.

   Display the status of the SS7 signaling links on the card you wish to remove by entering the rept-stat-slk command, specifying the card location and signaling link. The card location is shown in the CARD field of the rtrv-card command output.

   For this example, enter these commands.

   rept-stat-slk:loc=1201:link=a

   This is an example of the possible output.

3. Deactivate the links to the card that are not in an OOS-MT-DSBLD state using the dact-slk command.

   For this example, enter these commands.

   dact-slk:loc=1201:link=a

   dact-slk:loc=1201:link=b

   dact-slk:loc=1318:link=a

   dact-slk:loc=1311:link=a

   dact-slk:loc=1311:link=a1

   dact-slk:loc=1311:link=b

   dact-slk:loc=1311:link=b1

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

   rlghncxa03w 06-10-01 09:12:36 GMT  EAGLE5 36.0.0
   Deactivate Link message sent to card
   

4. Display the cards that are in service with the rept-stat-card:stat=nr command.

   rept-stat-card:stat=nr

   This is an example of the possible output.

5. If the signaling links on the card to be removed from the database is the last signaling link in a linkset, the force=yes parameter must be used with the dlt-slk command.

   To verify this, enter the rtrv-ls command with the linkset name shown in step 1 (LSET NAME field) or in step 2 (LSN field). For this example, enter these commands.

   rtrv-ls:lsn=sp1

6. Inhibit the card using the rmv-card command, specifying the card location.

   If the LIM to be inhibited contains the only signaling link in the linkset that in service, the force=yes parameter must also be specified. For this example, enter these commands.

   rmv-card:loc=1201

   rmv-card:loc=1318

   rmv-card:loc=1311

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

   Card has been inhibited.
   

7. Remove the signaling links on the specified card by using the dlt-slk command.

   If the output of step 5 shows that the signaling link being removed is the last signaling link in a linkset, the force=yes parameter must be used. For this example, enter these commands.

   dlt-slk:loc=1201:link=a

   dlt-slk:loc=1201:link=b

   dlt-slk:loc=1318:link=a

   dlt-slk:loc=1311:link=a

   dlt-slk:loc=1311:link=a1

   dlt-slk:loc=1311:link=b:force=yes

   dlt-slk:loc=1311:link=b1

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

   DLT-SLK: MASP A - COMPLTD
   

8. Remove the card using the dlt-card command.

   The dlt-card command has only one parameter, loc, which is the location of the card. For this example, enter these commands.

   dlt-card:loc=1201

   dlt-card:loc=1318

   dlt-card:loc=1311

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

   rlghncxa03w 06-10-01 09:12:36 GMT  EAGLE5 36.0.0
   DLT-CARD: MASP A - COMPLTD
   

9. Verify the changes using the rtrv-card command specifying the card that was removed in step 8.

   For this example, enter these commands.

   rtrv-card:loc=1201

   rtrv-card:loc=1318

   rtrv-card:loc=1311

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

   E2144 Cmd Rej: Location invalid for hardware configuration
   

10. Back up the new changes using the chg-db:action=backup:dest=fixedcommand.

    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.
