Removing Remote Loopback Points

This procedure is used to remove remote loopback points used by the link fault sectionalization feature from the database, using the dlt-lbp command. The dlt-lbp command uses these parameters.

:loc – The card location of the signaling link to be tested.

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

:lbp – Identifies the far-end loopback point that lies along a SS7 signaling link path between the EAGLE 5 ISS up to and including the target device.

:all – Are all loopback points for the specified signaling link to be removed

The specified loopback point must be in the database.

Either the lbp or all parameters must be specified, but not both.

This examples used in this procedure are used to remove the remote loopback point 5 on the signaling link assigned to card 1215, link B.

1. Display the existing loopback point values by entering the rtrv-lbp command. This is an example of the possible output.

2. Remove the loopback point from the database, using the dlt-lbp command. For this example, enter this command.

   dlt-lbp:loc=1215:link=b:lbp=5

   If all the loopback points on the signaling link are to be removed from the database, enter this command.

   dlt-lbp:loc=1215:link=b:all=yes

   When the command has completed, this message should appear.

3. Verify the changes using the rtrv-lbp command. This is an example of the possible output.

4. 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.
