摘要： A band control system of the present invention is applicable to a digital subscriber line network in which a first apparatus and a second apparatus situated at a subscriber station and a center, respectively, are interconnected by a metallic cable for interchanging at least a digital data signal with each other. The band control system includes a commanding device included in one of the first and said second apparatuses for monitoring the receipt of ATM (Asynchronous Transfer Mode) cells from the other apparatus and sending, based on the result of monitoring, a band variation command to the other apparatus to thereby cause it to vary a band by using a frequency band not used for signal transfer. A band varying device is included in the other apparatus for receiving the band variation command and varying the band in accordance with the command.
