Summary:

The increase in the amount of complex communication equipment in aircraft systems has caused problems which conventional approaches to interconnection of independent subsystems can no longer solve. Using point-to-point wiring penalizes aircraft performance in terms of space usage, weight, cost, and reliability.This paper presents multiplexing techniques in conjunction with solid state technology and systems integration as proposed methods which will provide a cost effective solution to aircraft interior communication problems. Two basic systems reviewed are time division and frequency division multiplexing.The proposed use of a digital interior communication system for the SST, and the criteria that no single failure in a common element would cause loss of a signal, led to development of four multiplex systems which are dual redundant. Other features of this system are weight/cost advantages, flexibility, maintainability, and redundancy which insures high operational reliability and flight safety.In conclusion, it is felt the state-of-the-art is capable of implementing the digital communication system and these techniques will significantly improve the operation of current and future aircraft
