Abstract

According to a network system of the present invention, a protocol information requesting unit of call-out terminal requests, when setting a call between terminal devices having different signaling protocols, an ATM switch to supply signaling protocol information used by a call-in terminal. A protocol information supplying unit of the ATM switch reads protocol information corresponding to the protocol information of the call-in terminal from a first protocol information storage unit, and supplies the call-out terminal with this piece of protocol information. A protocol changing unit in the call-out terminal changes the signaling protocol used by the call-out terminal to the signaling protocol used by the call-in terminal. There comes a status wherein the two signaling protocols become coincident.
