PURPOSE:To transfer data with a high reliability only with the execution of a violation by executing the bipolar violation of a status bit in the protecting time of an envelope synchronization when the data are transferred by the envelope system of a bipolar signal. CONSTITUTION:The envelope multiplexing signal of a timing circuit is composed of a frame bit F for envelope synchronization, a data bit D for information transfer, and a status bit S for status displaying. At the time of transferring the data of the second channel of this multiplexing signal, a pattern dissident to the frame pattern of prescribed synchronization is transferred to the frame bit F, a bipolar violation is executed to a status bit S in a synchronization protecting time Tp, and the status bit S is transferred. The transmission of the second channel is displayed by both of a synchronization protection due to dissidence to the frame pattern for synchronization and the violation of the status bit, and the bit error of status information is discriminated on a receiving side. |
