PROCEDURE
C.1 FAST System Overview
The CDM-625 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 purchase these unique, register-specific Fast
Access Codes from Comtech EF Data during normal business hours, and then load these codes
into the unit using either the front panel keypad or the CDM-625 Web Server (HTTP) Interface.
Contact Comtech EF Data Product Support to order the desired options.
See Table 1-2 in Chapter 1. INTRODUCTION or Sect. 5.2.8.1.1 in Chapter 5. FRONT
PANEL OPERATION for listings of the available FAST and FAST-accessible hardware
options.
FAST System Theory: FAST facilitates on-location 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 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
CDM-625 Web Server (HTTP) Interface.
FAST Accessible Options: Hardware options can be ordered and installed either at the factory or
in the field. Depending on the current hardware configuration of the unit, you can select options
that can be easily activated on-site. The FAST Access Code that is purchased from Comtech EF
Data enables configuration of the available hardware. The base CDM-625 unit is equipped with
Viterbi and Reed-Solomon codecs. It offers BPSK, QPSK, and OQPSK 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 EDMAC and AUPC.
