Abstract

Between transmitters (K1..Kn) and the transmission channel (C) clock pulse controlled converters regenerate the binary signals when entered into the transmission channel. In addition a test channel (Z) is provided into which the transmitted binary signals are fed directly, and without passing through the transmitted binary signals are fed directly, and without passing through the converters. Transmission to the channels (C,Z) is via separate concentrators (X1,..Xm,Y) for the test channel (Z) and (A1..Am) for the transmission channel (C). The information from the test channel is fed back to the transmitter and compared with the original for parity, bit for bit. Thus the signal sent (L1,P1,A...B) to the transmission channel (C) is compared with the original as recovered from the test channel (Z) through its return path (e). This check takes place between two timing pulses.
