FAST Options and Hardware Options
The Modem is extremely flexible and powerful, and incorporates a large number of
optional features. Some customers may not require all of these features, and therefore, in
order to permit a lower initial cost, the Modem may be purchased with only the desired
modules and features enabled. If, at a later date, a customer wishes to upgrade the
functionality of a modulator or demodulator, Comtech EF Data provides a system known
as FAST (Fully Accessible System Topology) which permits the purchase and
installation of options through the use of special authorization codes entered through the
front panel, or remotely.
The base configuration of the modulators and demodulators are equipped with Viterbi
and R-S codecs. It offers modulation types, and data rates up to 5 Mbps. It is, however,
limited to Closed Network operation.
