PROBLEM TO BE SOLVED: To prevent interruption of a relayed data communication signal, omission of a burst signal to be relayed, or generation of an erroneous burst signal or the like. SOLUTION: A data signal burst control signal is generated by a signal burst control circuit 21 based on time slot information for data communication sent in the case of line setting for data communication from a master station side detected by a timing information detection circuit 19. On the other hand, an incoming relay burst signal S1 received by a slave station detected by an incoming burst signal detection circuit 15 receives forward protection and backward protection only for a radio time slot for data communication of a data communication based on a transmission timing generated separately by a transmission timing generating circuit 14 at a forward/backward protection circuit 22. An incoming burst control circuit 23 controls relay transmission by the data signal burst control signal. |
