摘要： The present invention relates to a high-speed digital transmission method using an analog subscriber line (for example, an existing telephone-use copper cable), a subscriber accommodating system used in the high-speed digital transmission method, an accommodating device on a subscriber-terminal side and an accommodating device on an accommodating station side. The present invention includes the steps of providing a subscriber distributing device, to which a plurality of subscribers are connected, on a subscriber-terminal side of an analog subscriber line in a high-speed digital transmission method using the analog subscriber line; setting a low-frequency band part as a control channel; setting a high-frequency band part as one or a plurality of communication channels; and controlling the one or plurality of communication channels by use of the control channel. The plurality of subscribers communicate by using the same analog subscriber line.

摘要： A communication band setting method and a communication device that can change a communication band in the ascending and descending directions. The communication device includes a transmission/reception unit that transmits and receives a signal using a plurality of sub carriers, an information storage unit that stores information as to whether each of the plurality of sub carriers is used for transmission or reception, a control unit that changes the information stored in the information storage unit in compliance with a control instruction. A transmission/reception process of the transmission/reception unit is controlled in accordance with the information stored in the information storage unit, so that a transmission band and a reception band are suitably adjusted.

摘要： Network load is reduced by combining packets by considering the MTU of a transmission path. When a routing processing unit detects the transmission of a large number of packets addressed to the same destination network, a routing information gathering unit determines the MTU of a transmission path along which the packets are to be transmitted. A combining unit assembles a combined packet by combining packets up to a length that does not exceed the MTU of the transmission path, and sends out the combined packet.
