Abstract: The present invention relates to arrangements and methods in a Digital Subscriber Line (DSL) system. The basic idea of the present invention is to reserve a first part of an available frequency band exclusively for vectored DSL transmission and reception. The remaining part of the available frequency band can then be used either for only standard non-vectored transmission or for both for vectored DSL and for standard non-vectored DSL transmission. Therefore, the present invention makes it possible to get the full benefit of vectored transmission, on at least the first part of the frequency band, even if the DSL vector system cannot handle all DSL modems.

Abstract: The present invention relates to a vectoring chip unit in a DSL system connectable to a plurality of DSL ports of a DSL chip comprising 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/canellation 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.
