PROCEDURE
5.1 Overview
The CDM-625A 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

opology (
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-625A HTTP (Web Server) Interface.
See Table 1-2 in Chapter 1. INTRODUCTION or Sect. 6.2.8.1.1 in Chapter 6. FRONT
PANEL OPERATION 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-625A 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-625A 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
.
