A communications system programmable to operate at a selected one of multiple frequency ranges and any one of a plurality of modulations schemes and data rights including an open architectural bus line for linking a plurality of board level units. A single board receiver exciter operates to receive and transmit signals at a plurality of frequencies and contains means for interfacing the single board receiver exciter with the open architectural bus line. A single board modulator demodulator allows for modulation/demodulation and for encoding/decoding of signals. The single board modulator demodulator also includes means for interfacing with the open architecture bus lines so that instruction and programming commands may be received. A single board processor multiplexer controls operations of the single board receiver exciter and the single board processor multiplexer over the communications link created by the open architecture bus line. The communication system further comprises a multimedia processor chassis for physically enclosing the single board receiver exciter, the single board modulator/demodulator, the single board processor multiplexer, and the open architecture bus line.

Communications system using open architecture bus lines

A system for RF communications utilizing an open architecture bus line is disclosed. The system consists of a single-board receiver exciter, a single-board modulator and a system control processor all interfaced to a standard bus line. All three units are implemented on single-board assemblies and are programmable to perform over a variety of frequency ranges, to operate at one of a variety of modulating schemes, and to utilize varying data rates.
