  • Patent number: 3940566
    Abstract: The present invention relates to an arrangement in a time division multiplex link having at least two pairs of multiplexors and demultiplexors interconnected by separate transmission lines, i.e., redundant transmission systems, with delay, in which time division multiplex channels are formed through the cyclic scanning of the multiplexor inlets and demultiplexor outlets, respectively so that data signals presented to the multiplexor inlets are transferred via the time division multiplex channels in the form of sampling signals to regeneration arrangements connected to the demultiplexor outlets. The sampling signals passed over the separated (redundant) time division multiplex channels are interlaced, i.e., different delays on different transmission lines, thereby producing a resultant sampling density which, when a fault occurs, is reduced by a factor corresponding to the share of the faulty channel in the total number of channels.
