Appendix C. FAST Activation
C.1

Introduction

Fully Accessible System Topology (FAST) is an enhancement feature available in Comtech EF
Data products, enabling on-location upgrade of the operating feature set – in the rack – without
removing a modem from the setup.
This accelerated upgrade can be accomplished only because of FAST's extensive use of
programmable devices incorporating Comtech EF Data-proprietary signal processing techniques.
These techniques allow the use of a unique access code to enable configuration of the available
hardware.
The access code can be purchased at any time from Comtech EF Data. Once obtained, the access
code is loaded into the unit through the front panel keyboard.
The FAST options are linked to 3 option registers:

•
When an unlock FAST code is obtained from Comtech EF Data it will be for a specific register.
Register 1 is for Data Rate options
Register 2 is for L-band, Modulation type and Framing options
Register 3 is reserved for future options
