Appendix B. FAST Activation
Procedure
B.1 FAST System Overview
The CDM-740 is extremely flexible and powerful, and incorporates a large number of optional
features. In order to permit a lower initial cost, the modem may be purchased with only the desired
features enabled.
If, at a later date, a user wishes to upgrade the functionality of a modem, Comtech EF Data provides
Fully Accessible System Topology (FAST), which permits the purchase and installation of options
through special authorization codes loaded into the unit either via the front panel keypad or entered
remotely via the remote port located on the modem rear panel.
These unique access codes may be purchased at any time from Comtech EF Data.
FAST System Theory
FAST facilitates on-location upgrade of the operating feature set without removing a modem
from the setup.
With FAST technology, operators have maximum flexibility for enabling functions as they are
required. FAST allows an operator to order a modem precisely tailored for the initial application.
When service requirements change, the operator can upgrade the topology of the modem to meet
those requirements within minutes. This accelerated upgrade can be accomplished because of FAST’s
extensive use of the programmable logic devices incorporated into Comtech EF Data products.
FAST Implementation
Comtech EF Data’s FAST system is factory-implemented in the modem. All FAST options are
available through the basic platform unit at the time of order – FAST allows immediate activation of
available options, after confirmation by Comtech EF Data, through the front panel keypad or via the
remote control interface.
FAST Accessible Options
Hardware options for basic modems can be ordered and installed either at the factory or in the
field. The operator can select options that can be activated easily in the field, depending on the
current hardware configuration of the modem. A unique access code enables configuration of the
available hardware.
