Abstract
A connection for transmitting an ATM cell having a specified identifier through a predetermined interface is set in an ATM switch unit. A protocol control unit receives a call control signaling message from a user via the ATM switch unit. Connection cache data retains connection information which specifies the connection set within the ATM switch unit and indicates whether the connection is in an activate or halt state. A connection cache unit, when the call control signaling message received by the protocol control unit indicates a request to release any one of connections, sets the connection information specifying the connection so as to indicate the halt state. The connection cache unit, when the call control signaling message received by the protocol control unit indicates a request to set the connection for a certain call, allocates the connection indicated by the connection information showing the halt state to the call.
