A transmission link for transmitting a sequence of signals comprising pulse and interval signals, across a transmission medium from a transmitter to a receiver circuit of a receiver, whereby each pulse signal is modulated with a frequency. At least two frequencies are used to modulate the pulses, and a separate evaluation circuit is provided in the receiver for each modulating frequency. The output signals of the evaluation circuits are concatenated (linked in series) by a AND-gate circuit.
