摘要： A radio relay apparatus complying with SDH is provided which permits the value of B2 bytes received from a transmitting-side terminal station to be sent to a receiving-side terminal station even in the case where resetting of a pointer value is performed. B2 sampling means of the radio relay apparatus samples B2 byte information, and B2 recomputing means again performs B2 parity computation of received transmission information which has been subjected to the pointer value resetting. Adding means adds bit by bit the data sampled by the B2 sampling means to the data obtained by the B2 recomputing means, and transmitting means transmits the sum obtained by the adding means to a subsequent radio relay apparatus. Based on the sum transmitted from the transmitting means, the subsequent radio relay apparatus judges that data which is a subject of B2 parity computation and which corresponds to a bit having the value "1" is erroneous.
