Abstract
The present invention provides a management table that uses only specific symbols for upstream signals and other symbols for downstream signals, within a hyperframe (ADSL communication unit). Communication is performed by switching streams between the upstream and downstream, in accordance with the symbols stored in the management table. Upon transmitting a predetermined number of hyperframes, a processor transmits a SEGUE signal instead of a REVERB signal in the beginning of the next hyperframe.
