FX II Hardware Introduction

GCA39-824 Rev 2, Issue 4/02 Page 4 Printed in the USA

FXCPU-2 board comes with built-in Com ports and contains 3 different sets of memory that

are necessary for the operation, programming, and functionality of the communication

system.

• The board contains:

* 2 serial ports: (Programmable to 19,200 bps) These ports are non-dedicated; compatible

with serial printers and OAI applications (e.g., Wide Open Office), and can be used for direct

link programming.

* Operational Memory: Holds Flash, Scratch, and NOV RAM.

Flash: Used for system initialization, storing current feature sets, and establishing slot-

size capabilities. The Flash memory is retained by the super capacitors installed on the

FXCPU boards. The capacitors can maintain system programming for 65 hours.

Scratch: Workhorse memory for the board—RAM used for general telephony activities

(e.g., speed dialing, transferring, and call forwarding).

NOV (Nov-Volatile) RAM: It is used for SMDA storage (its standard use), and to

increase the system speed dial capacity.

NOV memory may need to be expanded to support an additional amount of SMDA

storage.
