    摘要： A PLC modem (131-133) is prompted to increase, starting from a predetermined minimum transmit power, a transmit power of data transmission on a PLC channel (112) at a given time or time period defined with respect to a mutual time reference of a DSL channel (111) and the PLC channel (112). A DSL modem (121) is prompted to measure a signal-to-noise value at the given time or time period defined with respect to the mutual time reference. Mitigation of interference 190 between the PLC channel (112) and the DSL channel (111) becomes possible.

    摘要： An apparatus comprising a first transceiver at a central office (CO) coupled to a second transceiver at a customer premise equipment (CPE) via a digital subscriber line (DSL), a crosstalk precoder coupled to the first transceiver at the CO, and a vectoring control entity (VCE) coupled to the transceiver via a feedback channel and to the crosstalk precoder, wherein the second transceiver comprises a noise monitor configured to detect non-crosstalk noise in a downstream signal from the CO to the CPE, and wherein the first transceiver is configured to receive a predefined special feedback signal from the second transceiver that indicates whether non-crosstalk noise is detected in the downstream signal instead of a measured error value.

    摘要： Embodiments of the present disclosure relate to an apparatus comprising means configured to perform: obtaining a measured channel frequency response, and a measured noise power spectral density for a line of a wired network susceptible to an impairment; deriving, in case of an indication of an impairment present on the line, from the measured channel frequency response and the measured noise power spectral density, a first theoretical noise representation for the line with the impairment and a second theoretical noise representation for the line without the impairment; and determining information indicative of a location of the impairment in the line, by processing the measured noise power spectral density, the first theoretical noise representation, and the second theoretical noise representation with a neural network. Further example embodiments relate to a method for determining information indicative of a location of the impairment, a computer program product, and a computer readable storage medium.

    摘要： A method for implementing an upstream symbol alignment within a network component, the method comprising receiving an upstream sync signal via an initializing digital subscriber line (DSL) during a channel discovery phase from a customer premise equipment (CPE), determining a corrected upstream symbol alignment value based upon the upstream sync signal, and transmitting the corrected upstream symbol alignment value to the CPE, wherein the upstream symbol alignment value determines an upstream symbol alignment for one or more upstream transmissions, and wherein the corrected upstream symbol alignment value is determined before receiving a plurality of upstream data signals within the data symbol positions during the channel discovery phase..
