Data restoring
In the unlikely event configuration data becomes corrupted, a backup copy of
the current database can be restored to the Option 11C and 11C Mini. There
are four possible areas of where a backup of configuration data can be
restored from — the secondary primary database, the backup flash drive, the
PCMCIA drive, or an external computer hard-drive. (Refer to Table 2 for a
description of the commands used to restore backup data to the Option 11C
and 11C Mini.)
Pre-programmed data
When an Option 11C or Option 11C Mini system is initially installed,
customer data must be entered into the overlay programs. Telephones, for
example, must be assigned features on their keys to allow them to function
properly.
However, the Main SSC or the Mini MSC can be pre-programmed with
customer data. If you load pre-programmed data into the system during
installation, some overlay entries will be automatically configured on the
telephones. For example, you can choose a telephone model that has
predetermined feature and key assignments and a preassigned class of

(see note)
43 Secondary primary files are “swapped” with the contents of
the primary flash drive (Refer to database.bak in Figure 2).
RES 43 Restore files to the primary flash drive from the PCMCIA
drive.
RIB 43 Restores the missing files in primary flash drive from the
internal backup drive.
XRT 143 Customer database records are restored from an external
computer hard-drive to the Primary and Backup Flash drives
on the NTDK20 SSC or NTDK97 MSC.
Note: The SWP command in LD 43 does not “restore” data to the primary flash drive: it swaps or replaces
the contents of the primary drive with the data stored in the primary drive’s secondary database.
