Abstract

In one embodiment, the line termination card includes a data output terminal configured to output a data sequence. The card further includes a vectoring entity configured to parse and encode the data sequence into frequency samples according to a carrier loading parameter, configured to scale the frequency samples into scaled frequency samples according to a carrier scaling parameter, and, configured to process the scaled frequency samples for crosstalk compensation. A controller is configured to adjust the carrier loading parameter and the carrier scaling parameter, and a forwarder is coupled to the data output terminal and to the controller. The forwarder is configured to forward the data sequence, the carrier loading parameter and the carrier scaling parameter towards a further line termination card.
