Summary:PURPOSE:To eliminate the need for scramble processing and code conversion at the transmission by using the 1st data frame signal as a data code and the 2nd data signal as a transition rule violation signal so as to encode the signals by a specific transition rule and multiplex them. CONSTITUTION:A data frame multiplex signal including information of two data frame signals is inputted to a data station 11 via an interface 10 and an input transmission line 12a from a network 1 and its output is outputted to the network 1 via an output transmission line 12b. The two data frame signals are subjected to multiplex by a transmission code having a specific transition rule at the station 11, e.g., a CMI code. In this case, the 1st data frame is used as a data signal and the 2nd data frame signal is used as a transition violation code and the signals are subject to coding and multiplex.
