FAST System Overview

The CDM-750 Advanced High-Speed Trunking Modem 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, the user wishes to upgrade the functionality of a modem, Comtech EF Data
provides Fully Accessible System Topology (FAST), which facilitates on-location upgrade of the
operating feature set without removing a modem from the setup.
FAST System Theory
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. If the user wishes to "unlock"
accessible features, FAST permits the purchase and installation of available options through
special authorization FAST Access Codes. These unique FAST Access Codes may be purchased
from Comtech EF Data during normal business hours. The codes are loaded into the unit either
via the front panel keypad or entered remotely via the remote port located on the modem rear
panel.
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 FAST Access Code is purchased that
enables configuration of the specific hardware upgrade.
