Abstract

A circuit arrangement for telecommunications installations, in particular for telephone communications installations, with central devices, in particular a central control mechanism, and individual devices, especially technical switching devices (for example, coupling fields with search devices itineraries and control, subscriber lines, identifiers, external and internal connection units, call impulse receivers, registers and the like) and with intermediate memories and/or transcoding devices, which are interconnectable with the individual devices through transmission lines. First transmission and, with the central devices, through second transmission lines, and that, in order to adapt the time conditions of the devices of both classes in the transmission of information between them, on the one hand, they are equipped, same as the individual devices, with emitting connecting organs and receivers of relatively slow work, especially of electromagnetic action, for the transmission lines of the first type and, on the other hand, as well as the central apparatuses, with connection organs emitters and receivers of relatively fast work, especially of action electronic, for the transmission lines of the second type, characterized in that the information is transmitted through multifilar transmission lines of the first type, with the help of a parallel code, while through the transmission lines of the second type, they are transmitted with the help of a serial code.
