Abstract
The connection is for transmission of a disturbance signal in a data transmission system as described in the principal patent. The transmission channel is divided according to the possibility of appearance of transmission disturbances into individual control sections between which are control stations. Each control station reintroduces in the two directions of transmission, at the start of each control section, at least one bit of the synchronising signal, as a message bit. The following station controls these message bits at the end of each control section. In the case of disturbance the control section following the disturbed control section returns at least one of the message bits with a logic value inverted from that of its instruction logic value.
