Abstract:
1. A method, comprising: providing, by a system comprising a processor, vectored digital subscriber line signaling from a first line terminal to equipment of a plurality of subscribers via a first set of wire pairs of a cable; monitoring, by the system, a second set of wire pairs of the cable that is not used for the vectored digital subscriber line signaling and that is not managed by the system, to estimate foreign interference introduced to the first set of wire pairs; and modifying the vectored digital subscriber line signaling responsive to the foreign interference by precoding symbols to be transmitted according to an adjustment of phase and amplitude of the symbols, by identifying frequency sub-bands in the vectored digital subscriber line signaling affected by the foreign interference, and by avoiding use of the frequency sub-bands or by adjusting a bit allocation or power allocation of the frequency sub-bands to deemphasize use of the frequency sub-bands.
