(FAST) OPTIONS
Comtech EF Data’s FAST system allows immediate implementation of different options
through the user interface keypad. Some FAST options are available through the basic
platform unit, while others require that the unit be equipped with optional hardware or
that the hardware be installed in the field.
The options available through the FAST architecture include:
Option Minimum Software Version
16QAM-DVB 7.1.2 *
8PSK-DVB 5.3.1 *
OEM LCD 2.1.2
* Note: Units that shipped prior to July 1998 requirea factory-installed hardware
upgrade to operate with 8PSK-DVB modulation.

HEORY
FAST is an enhancement feature available only in Comtech EF Data products, enabling
on-location upgrade of the operating feature set—in the rack—without removing a
modulator from the setup. When service requirements change, the operator can upgrade
the topology of the modulator to meet those requirements within minutes after
confirmation by Comtech EF Data. This accelerated upgrade can be accomplished only
because of FAST’s extensive use of programmable devices incorporating Comtech EF
Data-proprietary signal processing techniques. These techniques allow the use of a
unique access code to enable configuration of the available hardware. The access code
can be purchased at any time from Comtech EF Data. Once obtained, the access code is
loaded into the unit through the front panel keyboard or the rear remote port.
With the exclusive FAST technology, operators have maximum flexibility for enabling
functions as they are required. FAST allows an operator to order a modulator precisely
tailored for the initial application, reducing risk and cost overruns during the application
integration process.
