Underlying considerations of the problem outlined

EFFECTIVE COORDINATION of the activities of an electric utility necessitates the establishment of communication channels for the continuous flow of information into organization centers, and the prompt transmission of orders and suggestions from these centers to the points where action is taken. Voice communication appears to be especially adapted to meet these requirements, as is evidenced by the fact that about 85 per cent of the average electric utility´s communication expense is for transmission of the spoken word.
