PURPOSE:To prevent generation of a forecasting error in a slave station, by correcting a frame synchronizing signal in accordance with a present position of the slave station, making its corrected synchronizing signal a reference, and transmitting its own station burst by an assigned time slot. CONSTITUTION:In case when an adjacent station of a slave station 5 is a reference station 2, the slave station 5 is installed in the vicinity of the reference station before transmission is started, a terminal 12 is connected to a terminal 6, and a frame synchronizing signal oscillating source of the slave station 5 is set to a prediochronous synchronizing state. Also, in case when a slave station 3 joins newly in the course of transmission of the reference station 2, and transmission is started, a terminal 10 is connected to the terminal 6 before the transmission is started, and a frame synchronizing signal oscillating source of the slave station 3 is set to a prediochronous synchronizing state against the reference station 2. In this way, terminals 9, 9' of the slave stations 5, 5' after starting the transmission are capable of becoming a reference frame synchronizing signal supply source to other slave station which starts transmission newly, in the same way as a supply source 7, respectively. |
