PROBLEM TO BE SOLVED: To easily control a pulse transmitting timing by eliminating a synchronization error resulted from an up and down transmission delay difference specific to a digital synchronizing network. SOLUTION: This is a system in which a main station 1 and a slave station 5 which transmit and receive data are connected through a transmission path 3 so as to be faced to each other. The main station 1 is provided with receiving means 31, 33 and 23 which receive the data of the slave station 5 and obtain the other station pulse, a time interval measuring means 24 which measures a time since its own station pulse is transmitted until the other station pulse is received, and transmitting means 22 and 32 which transmit the measured time of the measuring means 24 to the slave station 5. The slave station 5 is provided with transmitting means 62 and 72, receiving means 71, 73 and 63 which obtain the other station pulse a time interval measuring means 64, and time adjusting means 65 and 66 which control the clock phase of a synchronizing network based on the measured time from the main station 1 and the measured time from the measuring means 64. |
