The objective of the study effort described in this report is to examine the advantagesdisadvantages resulting from the application of multiplexing as a replacement for the point-to-point wiring of the A-7D. As a result of this study, the following conclusions were reached The design and implementation of baseband transmission systems for 1-Mbps operation over twisted shielded pair media does not require that a new transmission line be developed. What is required is a more systematic design approach which allows appropriate trades to be made among the significant design parameters before any single parameters value is arbitrarily specified and fixed for all time. It is feasible to accommodate the signal interface and information transfer requirements imposed by avionics, electrical power distribution, and central integrated test in a single information transfer system. It is in fact desirable to combine these functions, since such a combination all but provides a realizable central integrated test capability as a natural fallout. Additonally, many of the signals which are in the avionics partition are also required for use in the power distribution electrical interlock function. Thus the need to supply a single signal to two or more separate systems is eliminated. There is sufficient commonality between the signal interfaceinformation transfer requirements of an Advanced Manned Bomber AMB and the A-7D to allow the same design concept for an information transfer system to be used for both aircraft.
