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.
