ABSTRACT:
A signal in HDBn code is transmitted with an auxiliary binary signal having a lower bit-rate on a digital transmission line. The HDBn code signal comprises predetermined sequences each including n+1 elements, n-1 central elements being zeros and a last element being a bipolarity violation mark. In each sequence of the HDBn code signal transmitted during each of binary elements of the auxiliary signal having a predetermined binary state, a bipolar mark in the sequence is permutated with a zero element having a predetermined rank in the sequence to derive an encoded sequence. The HDBn code signal is an information signal in the transmission line and the auxiliary signal can be a signal for remotely locating the repeater in the line from a monitoring end equipment of a monitoring system or for indicating performance factors of the repeaters, such as error rates, to the monitoring equipment.
