VECTORED DIGITAL SUBSCRIBER LINE SYSTEM HAVING MODULAR VECTORING ARRANGEMENTS

摘要

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.
