FAST Options and Hardware Options

The CDM-600L 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 Reed-Solomon 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.
