Abstract

1. A regenerator for digital signals, with an input-end Schmitt trigger (ST), and with a time decision device (SE) which is connected to the output of the Schmitt trigger, characterized in that the digital signals occur in the AMI-code, and that for the monitoring of the operation a code violation monitor (VM) is provided for the AMI-code, that the code violation monitor includes a change-over switch (T1, T2) which is controlled by a Schmitt trigger output signal delayed by one element period in comparaison to the input signal, and further includes two threshold value comparators (T3, T4 ; T5, T6) which are activated by said change-over switch and of which the first compares the input signal with the lower threshold voltage (UO) and the other compares the input signal with the upper threshold voltage (UI) of the Schmitt trigger (ST), that the signal input (ER) of the regenerator is connected both to an input of the regenerator is connected both to an input of the Schmitt trigger (ST) and to a first input (EI) of the code violation monitor (VM), that a second input (E2) of the code violation monitor (VM) is connected via a delay element (VL) to the path for the digital signals which follow the Schmitt trigger output, and that whenever code rule infringements are established an appropriate signal occurs at the output of the code violation monitor (VM).
