Abstract

PURPOSE:To decrease the man-hour by connecting between the common bus and the information transmission line as well as between the terminal and the information transmission line via the bidirectional photocoupler and then making the information lines between the terminal and the common bus into a pair. CONSTITUTION:Receiving start signal 120, synchronism extracting circuit 130 of controller 105 of telephone terminal 100 receives data until a fixed number of data is received in the case of the cynchronous system and until the stop signal arrives in the case of the a synchronous system each. After this, the direction of photocoupler 106 is switched toward common bus 110 from terminal 100. Thus the data transmitted from terminal 100 is sent to common bus 100 from switched photocoupler 108 via controller 109. Accordingly, the man-hour can be decreased by making the information transmission lines between the terminal and the common bus into a pair.
