CDM-800 Gateway Router
Introduction
1.3.8
Fully Accessible System Topology (FAST)
The CDM-800 is extremely flexible and powerful, and incorporates a number of optional
features. In order to permit a lower initial cost, the unit may be purchased with only the desired
features enabled.
If, at a later date, a user wishes to upgrade the functionality of the CDM-800, Comtech EF Data
provides Fully Accessible System Topology (FAST), which permits the purchase and installation
of options through special authorization codes. These unique FAST Access Codes may be
purchased at any time from Comtech EF Data and loaded into the unit using the Web Server
Interface.
FAST System Theory
FAST facilitates on-location upgrade of the operating feature set without removing a unit from
the setup. With FAST technology, operators have maximum flexibility for enabling functions as
they are required. FAST allows an operator to order a unit precisely tailored for the initial
application.
When service requirements change, the operator can upgrade the topology of the unit 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 unit. 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, using the Web Server Interface.
See Appendix A. FAST ACTIVATION PROCEDURE for further information.
FAST Accessible Options
Hardware options for basic units 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 unit. The unique FAST Access Code provided for upgrade enables
configuration of the available hardware.
The following table shows the available FAST and FAST-accessible hardware options:
