device, called the Primary Flash Drive, is located on the Software
Daughterboard on the NTMW01 SSC. It contains Option 11C Compact

system.
The second Flash Drive, called the Backup Flash Drive, stores user
changeable files such as configuration data and the second copy of the
customer database. The Backup Flash Drive is in a physically different
location on the NTMW01 SSC so that in the unlikely event of a Primary Flash
Drive failure, a backup set of customer data can be retrieved and loaded into
the system’s active database.

customer data. It is also used to deliver and load the system software and
customer data base in a new system installation.

is used to identify the system. It allows the activation of features assigned to
the system through the validation of a series of keycodes.
