The Option 11C or Option 11C Mini is remotely "sysloaded" with cus-
tomer records stored in the Primary Flash drive.
Customer files stored on an external computer are verified for validity and
integrity with records in the Backup Flash drive.

An Option 11C and 11C Mini "SYSLOAD" is a sequence of events whereby
the switch loads and verifies system and customer records into the NTDK20
SSC's or NTDK97 MSC's active memory area, or DRAM. The flow of data
depends on the status of the software - new installation, software release
upgrade, or a user-initiated sysload - or the commands initiated in either
LD 143, or the Install Setup Program.
Despite the various ways to initiate a Sysload, the flow of data generally
follows the path described below (Refer to Figure 2 for a graphical
illustration):
1 The Option 11C and 11C Mini searches for customer records in the
Primary Flash drive. If the files are located and verified, data is loaded
into the NTDK20 SSC's or NTDK97 MSC's DRAM.
2 If the records are corrupt or cannot be found in the Primary Flash drive,
the system searches the Backup Flash drive. If the customer records are
located and verified, the Option 11C and 11C Mini loads the data into
DRAM.
