Abstract

PURPOSE:To prevent mis-matching of a communication speed by transmitting and receiving mutually in a speed possible for communication by a data terminal equipment so as to decide mutually the communication speed before data communication is started between data terminal equipments. CONSTITUTION:A connection path switching circuit 101 of a communication speed decided and notifying system is arranged between a communication network connecting section 102 and a data terminal equipment 103 and the data communication path from a communication network is switched to the equipment 103 or a specific code transmission circuit 104 and a specific code reception circuit 105. Further, a communication speed switching circuit 106 is connected to the circuit 104 and a central control circuit 107 is connected to the circuits 104, 105 and the switching circuit 106. Then the circuit 101 and a communication speed display device 108 are connected to the control circuit 107. Before the data communication speed is started between terminal equipments, the data terminal equipment 4 transmits/receive mutually in a speed possible for communication to decide the communication speed mutually thereby preventing the mis-matching of the communication speed.
