PROBLEM TO BE SOLVED: To correctly detect the overlapping of burst signals by inserting respective pieces of information of starting/ending to the respective bytes of the starting/ending of the burst signal with fixed length so as to transmit it. SOLUTION: In a transmitting part 10, starting information and ending information having a prescribed pattern as against the transmission burst signal with fixed length L in its leading byte and ending byte are respectively inserted by a starting/ending byte inserting part 11 and transmitted. In a receiving part 20, a starting/ending byte extracting part 21 respectively extracts the starting byte and the ending byte. The position of the starting byte is judged by the arrival of the burst signal, the position of the ending byte is predicted by the starting byte since the length L of the burst signal is fixed and the ending byte is extracted at the predicted position. In a judging part 22, the respective patterns of the starting byte and the ending byte are compared with the respective patterns which are previously stored in a starting/ending byte pattern storage part 23 so as to judge normality/abnormality. |
