Removing the E1 Interface Parameters

This procedure is used to remove an E1 interface from the database using the dlt-e1 command using these parameters.

:loc – The location of the E1 card (card type lime1) containing the E1 interface being removed.

:e1port – The E1 port on the E1 card containing the E1 interface being removed.

The E1 interface to be removed must exist in the database. This can be verified in step 1.

To remove the E1 interface information contained on an E1 card, all signaling links serviced by that E1 card must be removed from the database. This can be verified with the rtrv-e1 command, specifying the card location and E1PORT on the E1 card, and the rtrv-slk command, specifying the location of any cards (E1 or channel cards) shown in the rtrv-e1 output. If there are any signaling links being serviced by the E1 card, go to the Removing an SS7 Signaling Link procedure and remove these signaling links.

Even numbered E1 ports cannot be removed if the even numbered E1 port is channel bridged. Remove the corresponding odd numbered E1 port (see Table A-5) to remove the even numbered channel bridged E1 port.

Display the existing E1 interfaces in the database using the rtrv-e1 command with no parameters.

If the E1 port being removed is an even numbered E1 port and is channel bridged, select the corresponding odd numbered E1 port to remove (see Table A-5) and go to step 2.

If the even numbered E1 port is not channel bridged, it can be removed with the dlt-e1 command. go to step 2.

Display the timeslots that are serviced by the E1 card containing the E1 interface information to be removed using the rtrv-e1 command specifying the card location and the e1port value from step 1. For this example, enter this command.

If this step shows any timeslots that are serviced by the E1 card, go to the Removing an SS7 Signaling Link procedure and remove the timeslots and signaling links serviced by the E1 card.

Remove the E1 interface information to the database using the dlt-e1 command specifying the card location of the E1 card and the E1PORT on that card. For this example, enter these commands.

dlt-e1:loc=1201:e1port=2
Verify the changes using the rtrv-e1 command with the card location and the e1port value specified in 3 .
For this example, enter this command.

rtrv-e1:loc=1201:e1port=2

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.
