Abridgment of long distance cable circuit for program transmission
The rapid growth of the telephone cable network in this country has made it desirable to develop a system whereby this network may be utilized to transmit programs for broadcasting stations over distances upwards of 2000 mi. Such a system has recently been developed and given a trial with very satisfactory results on a looped-back circuit 2200 mi. long. It transmits ranges of frequency and volume somewhat in excess of those now handled by the open-wire circuits which are used for program work, and also in excess of those handled by present-day radio broadcasting systems when no long distance lines are involved. The paper deals first with the transmission requirements of broadcasting systems and then gives a description of this new cable system.
