<p>PURPOSE:To operate the system by having only to mount only one basic clock oscillator to one complete set of the full duplex data transmission system. CONSTITUTION:The data transmission system in which a data is sent from one equipment to the other equipment as a serial data uses a transmission line code by which a clock is extracted from the signal, the transmission system of the one equipment converts the data into the transmission line code synchronously with the basic clock generated by a basic clock oscillator and sends the resulting data, and the other equipment extracts the clock from the received transmission line code and uses the clock as the basic clock of the other equipment to activate the transmission system of the equipment and the basic clock oscillator is mounted only to the transmission system of the one equipment as the feature. Since the basic clock oscillator is mounted only to the transmission system of the one equipment, the increase in the cost of the basic clock oscillator generating the basic clock attended with the high speed data transmission is suppressed and the mount space of the basic clock oscillator is reduced.</p> |
