Abstract: A device for managing signal transport, on a cable level, in a communication system, and a method for using same, are provided herein. The device is connectable between one or more access multiplexers (e.g., Very-high-speed Digital Subscriber Loop Access Multiplexer (VDSLAM) or a switch) and a cable in said communication system. The device includes: a plurality of access multiplexer-side transceivers connectable to access multiplexer-related physical medium, associated with said one or more access multiplexers; a plurality of customer-side transceivers connectable to respective customer-related wire pairs of said cable; and a processor connected to said access multiplexer-side transceivers and said customer-side transceivers, said processor comprising means for reducing crosstalk among said customer-related wire pairs. In some embodiments, vectoring is used for the crosstalk reduction, thus implementing a so-called cable level vectoring (CLV).

Abstract: A system and method for providing a service over a repeatered link that couples a service provider transceiver to a remote modem, the method includes: computing, for each frequency bin out of multiple frequency bins of a spectrum, a level of far-end cross-talk (FEXT) interference that is generated to a network-side receiver of a frequency division multiplexing (FDM) discrete multi tone (DMT) repeater by a service provider transmitter that provides an FDM DMT service that is supported by the FDM DMT repeater; computing, for each frequency bins out of the multiple frequency bins, a highest allowable transmit power level of a customer-side transmitter of the FDM DMT repeater that generates to the network-side receiver of the FDM DMT repeater a cross-talk interference that does not exceed a level of FEXT interference that is generated to the network-side receiver of the FDM DMT repeater by the service provider transmitter.

Abstract: Mitigation of spectral interference in communications systems such as Digital Subscriber Loop (DSL) systems, and in particular mitigation of spectral interference using dynamic spectral shaping (DSS) in DSL systems, and in particular Single-pair High-speed DSL (SHDSL) systems.

Abstract: A DSL communication system and a method for configuring a DSL communication system. The method includes training at least one anchor DSL modem transmitter to transmit information over at least one anchor line at an anchor bit rate that is determined based on an allowable tolerable noise level and a minimum allowable signal-to-noise ratio (SNR) margin; training one or more other DSL modem transmitter to transmit information over one or more other line at a bit rate that is determined by a current noise level and a target SNR margin, wherein the target SNR margin is higher than the minimum allowable SNR margin; and transmitting information by at least one trained DSL modem transmitter to at least one DSL modem receiver.
