Abstract

Systems and methods for increasing data capacity in communication systems is presented. In one embodiment, line chracteristics aredetermined (930), and a downstream bandwiddth (940) is adaptivelyallocated in respense to the determined line characteristics. In this regard, the upstream and downstream bandwidths may be seen as adaptively changing as a fonction of the line characteristics.
