ABSTRACT:
A band control system for 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 cable for interchanging at least a digital data signal with each other. The system may cause one of the first apparatus or the second apparatus to monitor receipt of signals from the other of the first apparatus or the second apparatus; send, based on a result of monitoring, a band variation command to the other apparatus for causing the other apparatus to vary a band by using a frequency band not used for signal transfer; cause the other apparatus to receive the band variation command; and vary the band in accordance with the band variation command.
