Option 11C and 11C Mini
Technical Reference Guide
Additional memory, referred to as DRAM on the NTDK20 SSC card, stores
and processes temporary automated routines and user-programmed
commands. The NTDK20 SSC card also retains a copy of customer files in
the event of data loss, in an area called the Backup flash drive.
The NTDK20 SSC card’s Flash daughterboard (the NTTK13), performs the
significant portion of system software storage and data processing for the
Option 11C.
NTTK13
The NTTK13 is a 48 Mbyte daughterboard comprised of Flash ROM and
Primary Flash drive.
•
The Flash ROM holds 32 Mbytes of ROM memory, comprising
operating system data and overlay programs. Flash ROM is expandable
using an expansion flash daughterboard.
•
The Primary Flash drive contains 16 Mbytes of storage space. Most of
the data storage is allocated to the Primary Flash drive - the main storage
area of customer configured data.
The boot code on existing SSC (Option 11C) cards must be NTDK34FA
Release 07 or later to support the NTDK81 or NTTK13 Flash
Daughterboards. It is recommended that the boot code be upgraded to the
latest issue every time the software is upgraded. The boot code can be found
on the programmed PCMCIA card.
Note:
New Option 11C systems will have the latest version of software
pre-programmed on the software daughterboard.
Other system data such as the Secure Storage Area (SSA) also resides in the
Flash drive. The SSA holds data that must survive power-downs.
Boot ROM is a 2 Mbyte storage device located on the NTDK20 SSC card’s
motherboard. It is comprised of boot code, system data, patch data and the
backup copy of the Primary Flash drive’s customer database.
