Chapter 5. FAST ACTIVATION
5.1
Overview
The CDM-425 Advanced Satellite Modem incorporates a number of optional features. In order to
permit a lower initial cost, you may purchase the unit enabled with only the desired features.
If you wish to upgrade the functionality of a unit at a later date, Comtech EF Data provides Fully
Accessible System Topology (FAST), which permits the purchase and activation of options
through special authorization codes. You may contact Comtech EF Data Product Support to
purchase these unique, register-specific Fast Access Codes, and then load these codes into the
unit using either the front panel keypad or the CDM-425 HTTP (Web Server) Interface.

See these chapters for listings of the available FAST and FAST-accessible
hardware options.
FAST System Theory: FAST facilitates on-site upgrade of the operating feature set without
removing a unit from the setup. FAST technology allows you to order a unit precisely tailored for
the initial application. When your service requirements change, you can upgrade the topology of
the unit to meet these requirements within minutes. This accelerated upgrade is possible because
of FAST's extensive use of the programmable logic devices incorporated into Comtech EF Data
products.
FAST Implementation: Comtech EF Data implements the FAST system in the modem at the
factory. 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 CDM-425 HTTP (Web Server) Interface.
FAST Accessible Options: You may order hardware options for installation either at the factory,
or you can install and activate them on-site. The FAST Access Code that you purchase from
Comtech EF Data enables configuration of the available hardware. The base CDM-425 unit is
equipped with VersaFEC and VersaFEC-2 codecs. It offers BPSK and QPSK modulation types,
and data rates up to 5.0 Mbps, with all interface types. While it is limited to Closed Network
operation, it also includes Embedded Distant-end Monitor and Control (EDMAC) and Automated
Uplink Power Control (AUPC).
