A method for establishing bidirectional connections and multiple connections performed by an ATM switching device is disclosed, and the method may include the steps of recognizing a connection request message sent from one calling subscriber, including information concerning other n-1 called subscribers in the asynchronous transfer mode switching device transmitting the connection request message to the n-1 called subscribers, and transmitting a response to the calling subscriber from the n-1 called subscribers from the asynchronous transfer mode switching device; and establishing bidirectional connections between the calling subscriber and the called subscribers.
