Assigned DNs
The Assigned DNs tabbed panel displays the DN properties for lines that are assigned to
telephones.
This information can also be configured on the DN record. Any information added, deleted or
modified in this table reflects in the DN record.
Restoring system data
If the programming of lines and extensions is incorrect, you can restore from an archive file, or
you can restore the system to factory defaults. This section provides the procedures to follow to
restore system data from an archive file, and to restore factory defaults. For information about the
effects of performing a restore operation, or about optional components, see the BCM450
Administration and Security Guide (NN40160-601)
Restoring data from an archive
To restore data from an archive
1 In the task panel, click the Administration tab.
2 Open the Backup and Restore folder, and then click Restore.
The Restore panel opens. The Restore From selection field has BCM as a default value.
3 In the Restore From selection field, select the location of the archive file to restore:
• BCM
• My Computer
• Network folder
•FTP server
•SFTP server
• USB storage device
•Factory Default
4 Click the Restore button.
The Select Components to Restore window opens.
Note: Lines that do not allow single-line assignment, such as PRI lines and VoIP lines,
will not display this tabbed panel.
Caution: A backup operation can interrupt services running on the BCM450. A
warning displays whenever the backup will cause a service interruption. If you
want to perform a backup that does not affect the system, you can exclude
services that would be affected. Alternatively, you can include these services and
perform a backup at a time when the system is typically not in use.
