Abstract: A communication systems (100) comprises terminals (103, 104) and an intermediate server (101) that notifies destination information for determining the address of the second communication terminal on the network. The terminal (103) transmits to the intermediate server (101) a request message for requesting the destination information.

Abstract: To realize an ATM cell switch capable of reducing the transmission rate of cells to be transmitted, a output buffer-type ATM cell switch includes input units buffer unit, and output units, wherein the buffer units reduce the transmission rate of the cells. Furthermore, the ATM switch compares the destinations of the cells with destination set signals that are provided to address filter units in the buffer units, and controls the transfer of cells to the buffer memories in the buffer units, thereby efficiently reducing the transmission rate of cells.

Abstract: A facsimile system includes a base station connected to a wire network, and a plurality of extension sets connected to the base station through radio networks. The base station includes an NCU (Network Control Unit) for receiving an image signal received through the wire network, a printer for outputting an image corresponding to the image signal received by the NCU, a control circuit for calling an extension set in response to a call signal received through the wire network, a switching circuit for connecting the wire network to the NCU in response to a response signal transmitted from the called extension set, and a transceiver for receiving the image signal transmitted from the extension set and sending the image signal to the wire network.
