Abstract:

A communication system wherein a plurality of remote stations are serially connected in a communication loop to a Control Station. Communication of intelligence to and from the remote stations and to and from the Control Station is by way of high frequency bits which are introduced serially and circulate through the loop. An inoperative remote station is bypassed by introducing into the station to be bypassed a D. C. signal of controlled magnitude, duration and polarity, which, through the required instrumentalities, disconnects the station from the communication loop while maintaining the integrity of the loop.
