<p>PROBLEM TO BE SOLVED: To improve transmission efficiency by packeting 1st response data preferentially rather than 2nd response data and user data corresponding to packets to be transmitted through an outgoing low-speed transmission system and transmitting these 1st response data through an incoming low-speed transmission system. SOLUTION: The data packet to be transmitted through an outgoing high- speed transmission system 3 is inputted from a 1st reception part 11 to a 1st data packet inspection part 12, the error is inspected, and the inspected result is dispatched to a data packet part 19 as the 1st response data. The data packet to be transmitted through a 2nd low-speed transmission system 4 is inspected at a 2nd data packet inspection part 15, and the 2nd response data are delivered to the data packet part 19. The data packet 19 receives two responses and the user data generated at a 2nd station, stores them, packets these data while selecting them and deliveres them to a transmission part 18. At such a time, the 1st response data are packeted and delivered to the transmission part 18.</p> |
