FAST Options and Hardware Options
The CDM-600 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
features enabled. If, at a later date, a customer wishes to upgrade the functionality of a
modem, 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 unit is equipped with Viterbi, Sequential and R-S codecs. It offers BPSK,
QPSK, and OQPSK modulation types, and data rates up to 5.0 Mbps, with all interface
types. It is, however, limited to Closed Network operation, but includes EDMAC and
AUPC.
