Abstract

A circuit arrangement for telecommunication systems and particularly for time division multiplex operation telephone switching systems characterized in that the incoming and outgoing conversation addresses of the time division multiplex beam are terminated, each by an amplifier of small input and output impedances, respectively, and that the opposite ends of the time-division multiplex beams are each terminated by a resistance equal to the characteristic beam impedance.
