Abstract
A telephone system comprises a non-loaded, non-equalized cable interconnecting a pair of communication terminals so that audio signals are translated in one direction and modulated carrier signals are translated in the other direction. A direct current bypass circuit is provided at each terminal to allow the transmission of direct current supervisory signals and battery potential over the non-loaded, non-equalized cable.
