PURPOSE:To avoid the contention between terminal equipments or between a terminal equipment and an exchange during communication and the area split loss when a virtual channel identifier is acquired by deciding the virtual channel identifier for incoming and outgoing communication used to identify the communication depending on the special method. CONSTITUTION:Terminal equipments T22-T24 and an exchange E are provided respectively with a reception virtual channel identifier idle/busy management table, a virtual channel identifier conversion table and a virtual channel identifier conversion section, and they inform the virtual channel identifier acquired from an idle area in the reception virtual channel identifier idle/busy management table and used for the reception to each other. The terminal equipments and the exchange set the virtual channel identifier informed with each other to the virtual channel identifier conversion table and the virtual channel identifier in the virtual channel identifier area added to information in the information transfer phase is revised into the virtual channel identifier with the virtual channel identifier table and the information from the outgoing side is transferred to the incoming side or vice versa, respectively.
