摘要： The present invention relates to methods and apparatuses for sensing noise sources in a wireline communications environment such as a customer premises environment in a DSL system. In embodiments, the invention includes an additional sensor that is connected to power mains in a DSL customer premises environment either to characterize, at their source, noises coupling into the DSL lines, and/or to mitigate their impact into the DSL lines. One objective is associated with diagnostics that help to better characterize the noise signals themselves and derive correlation of signals sensed from the power mains and their possible projection onto the DSL line. Another objective makes use of these power line sensor signals to mitigate or to eliminate power line noises that make their way onto the DSL line. Example embodiments further include and exploit signals from additional secondary sensors such as secondary common mode, differential mode and phantom mode sensors.

摘要： A crosstalk processing method, an apparatus, and a system comprise a transceiver of a line that generates, respectively according to pilot sequences allocated by a vectoring control entity, pilot training signals that are within different spectral ranges and that satisfy a preset relationship with a pilot training signal of another line such that a receiver of the line can determine sample errors respectively according to the different pilot training signals. A vectoring control entity then determines crosstalk channel coefficients from the other line into an inband spectrum and an out-of-band spectrum of the line, and performs precoding processing on a to-be-sent data signal of the line to eliminate impact of crosstalk from the other line to the inband and out-of-band spectrums of the line.

摘要： Methods, systems, and devices are described for wired communication. In one aspect, a distribution point may use a redundant number of digital subscriber line (DSL) lines that share a same cable binder to cancel crosstalk. For example a first distribution point may use a redundant number of lines, which may be virtualized lines, to cancel interference between lines controlled by the first distribution point and lines controlled by a second distribution point. In some cases, a distribution point may share precoding and cancelling coefficients with another distribution point over a cloud network or other service to enable vectoring without sharing transmitted data between the two distribution points. That is, the first distribution point may receive information related to crosstalk between sets of CPEs without receiving data transmitted by a separate distribution point sharing the same cable binder, and use the crosstalk related information to cancel crosstalk.

摘要： A reduced-memory vectored DSL system reduces the bandwidth and memory storage demands on a vectored DSL system in which FEXT data is transmitted and stored. When test signal data, such as training and/or tracking data, is sent to determine FEXT characteristics of the DSL system, error signals are available for all or substantially all of the upstream and/or downstream frequency band DSL tones used in the system. Dividing a frequency band into sub-bands, only a subset of tones in each sub-band is used for deriving FEXT data. For tones in the sub-band subsets, full-precision FEXT data values can be derived. For other tones, approximations of the FEXT data can be derived. Memory is reduced in both the transmission of such FEXT data (between upstream and downstream ends) and within an upstream-end device such as a DSLAM that performs vectoring using a separate or internal vectoring processing apparatus.

摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for diagnosing and optimizing vectored DSL lines. For example, in one embodiment, such a system includes an interface to a first subset of a plurality of digital communication lines allocated to a vectored group and to a second subset of the plurality of digital communication lines which operate external to the vectored group; a Dynamic Spectral Management server (DSM server) to analyze the vectored group by performing the following operations for each of the plurality of digital communication lines in the vectored group: measuring a mitigated noise level for the digital communication line with crosstalk cancellation active, measuring a non-mitigated noise level for the digital communication line with crosstalk cancellation inactive, and comparing the mitigated noise level measured on the digital communication line with the non-mitigated noise level measured on the digital communication line. In such an embodiment, the DSM server of the system further issues optimization instructions based on the analysis. For example, by issuing optimization instructions for the vectored group, for lines external to the vectored group, or for both.

摘要： A DSL transmitter and receiver are disclosed that are capable of accurately measuring crosstalk in G.vector-compliant DSL lines resulting from a legacy line. During crosstalk measurement, the legacy line can be placed in a showtime mode. Once in showtime mode, a data signal designated for the legacy line is reduced in power spectrum density and/or spectrum to reduce its effects on crosstalk measurements. An O-P-Vector-1 signal is then superposed on the reduced data signal, and the resulting test signal is transmitted over the legacy line while sync signals are transmitted over neighboring G.vector lines. The receiver can then accurately measure the crosstalk on the neighboring lines, and report back to the transceiver for adjustments. A similar configuration can be performed in a diagnostic mode of the legacy line.

摘要： In one embodiment, a node in a network receives communication channel data regarding one or more communication channels available between a particular device in the network and a neighboring device. Each communication channel corresponds to one or more electrical phases over which the particular device can communicate with the neighboring device. The node also receives crosstalk data regarding an amount of crosstalk between the electrical phases over which the particular device can communicate with the neighboring device. The node then generates a routing path for the network based on the received crosstalk and communication channel data.
