The present invention relates to a vectoring chip unit (400a,...,400d) in a DSL system connectable to a plurality of DSL ports (600a,...,600d) of a DSL chip. The vectoring chip unit comprises means for receiving data from each of the plurality of DSL ports, means for performing pre-coding/ cancellation in order to reduce crosstalk and means for transmitting a result of the precoding/ cancellation to the respective DSL port. Preferably, a system is provided comprising a plurality of said vectoring chips, whereby each vectoring chip is adapted to handle pre-coding/ cancellation of a predetermined frequency range and the frequency ranges of each vectoring chip are non-overlapping. |
