ABSTRACT:
A communication apparatus and method utilizing a Digital Subscriber Line (xDSL) modem that is selectively connected to a central communication apparatus to perform a full duplex communication. A communicator transmits a plurality of Mode Request (MR) signals to the central communication apparatus. The plurality of MR signals requesting that the central communication apparatus respond by transmitting a plurality of Mode Select (MS) signals to the communication apparatus. The plurality of MS signals designate a particular communication mode. First frequencies utilized by the plurality of MR signals and second frequencies utilized by the plurality of MS signals belong to a mutually different band. Further, the plurality of MR signals carry identical data with an identical timing, but have different carrier frequencies.
