ABSTRACT:
A digital regenerator line includes in each station a status and error detection arrangement having an error detection circuit (64) responsive to a filtered composite output signal (101) from a low-pass filtered output from a digital regenerator (30) using quantized feedback. The filtered composite signal includes a stressing signal and a quantized feedback error burst. A high-pass filter (71) is responsive to the filtered composite signal for removing the stressing signal and for passing the quantized feedback error burst. First and second threshold comparators (72 and 76) responsive to the quantized feedback error burst produce a burst signal when the amplitude of the quantized feedback error burst crosses a predetermined threshold (V.sub.R1 or V.sub.R2). The occurrence of the burst signal is determined to indicate that an error has occurred in the output of the digital regenerator.
