Abstract

PURPOSE:To economize a transmission line by using a main signal at intervals of a certain number of bits as well as an auxiliary signal including a bipolar code rule violation. CONSTITUTION:Two bits appearing at each interval of n bits in a main signal Sm consisting of a bipolar signal have four kinds of patterns. Through it is impossible to know which pattern will appear, they are allowed to correspond to logical '1' and '0' of an auxiliary signal Ss. The distinction between one logic and the other is expressed as the presence/absence of bipolar code rule violation (*). When logical '0' of the auxiliary signal Ss is expressed, the bipolar code rule violation is not included in the main signal Sm. When logical '1' of the auxiliary signal Ss is expressed, the bipolar code rule violation is included in the main signal Sm. The main signal Sm transmitted in this manner is received by a destination terminal station and is received as the auxiliary signal Ss also each interval of n-bits. The presence/absence of code rule violation is detected in this reception system to discriminated. '1' and '0' of the auxiliary signals.
