Abstract

PURPOSE:To prevent the passing each other of a message from generating by abolishing a packet when a PMX awaits a confirming signal and the unexpected data packet is received. CONSTITUTION:When a message for a receiving side terminal 46 is transmitted from a transmitting side terminal 43, a transmitting side PMX42 makes the message into the data packet, sends it to a receiving side PMX45 and its own station is set to the condition of the confirming signal waiting. The receiving side PMX45 judges first whether the received packet is the data packet or the confirming signal packet. When the packet is judged to be the data packet, it is judged whether or not its own station is the confirming signal waiting condition, when the station is not the confirming signal waiting condition, the packet is sent to the receiving side terminal 46, and when the station is the confirming signal waiting condition, the packet is abolished and it is awaited that the confirming signal packet comes.
