    摘要: The present invention relates to a method for jointly processing Discrete Multi-Tone DMT communication signals making use of a common tone spacing and to be transmitted over, respectively received from, a plurality of subscriber lines (L 1 .. L 4 ). DMT communications over a first subset (L 1 , L 2 ) of the plurality of subscriber lines is confined within a first transmit spectrum (17a), and DMT communications over a second disjoint subset (L 3 , L 4 ) of the plurality of subscriber lines is confined within a second extended transmit spectrum (35b) that is a frequency extension of the first transmit spectrum. The method comprises inputting first groups of frequency samples (u i,K-k ) to be transmitted over, respectively received from, the first and second subsets of subscriber lines at respective first tones (K-k) and following a first group selection order, alternated with second mirrored groups of frequency samples (u i,K+k ) to be transmitted over, respectively received from, the second subset of subscriber lines at respective second mirrored tones (K+k) of the first tones, and following a second mirrored group selection order of the first group selection order, to a vectoring processor (120) for joint mitigation of first crosstalk present over the first and second subsets of subscriber lines at the respective first tones and second crosstalk present over the second subset of subscriber lines at the respective second tones. The first tones are common to the first and second transmit spectra. Mirroring is with respect to a folding frequency (K) derived from a reference sampling frequency applicable to the first subset of subscriber lines.

    摘要: The present invention provides a method and a device for line initialization. In the method, first, a first precoding matrix required by a first part of subcarriers is acquired in a downstream direction, and then multiple data signals of all data signals that need to be sent in an initialization process are sent by using only the first part of subcarriers; afterward, a second precoding matrix required by at least a second part of subcarriers of all available subcarriers is acquired, and remaining data signals of all the data signals exclusive of the multiple data signals are sent by using the at least second part of subcarriers to complete line initialization. By using the foregoing manner, the present invention can cancel crosstalk between lines while completing line initialization, and does not easily cause transmit power to exceed a limit.

    摘要: This invention relates to a method of managing a digital subscriber line, where an optimum point at which to trigger a line test on the DSL line is determined. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, an electrical line test is triggered. Thus, monitoring is done in the DSL domain, but the line test triggered is in the electrical domain. In an improved method, moisture level sensors provide a measure of the atmospheric moisture levels experienced by the line. If the SNR margin measurements fail to meet the predetermined conditions, and in addition there is a correlation with atmospheric moisture levels, then a line test is triggered on the line. This improvement picks up faults associated with wet joints that are generally intermittent in nature, and otherwise difficult to identify and properly test.

    摘要: This invention relates to a method of managing a digital subscriber line, where classification for a potential fault on a line is generated. The invention continuously measures the signal to noise (SNR) margin on the DSL line, and compares the measurements to predetermined conditions based on SNR margin characteristics associated with a population of good lines. Once the SNR margin measurements fail to meet the predetermined conditions, the line is flagged as experiencing a potential fault. Further measurements from weather sensors are gathered, and correlated with the SNR margin characteristics. The resulting correlation is used to generate a classification of a potential fault on the line. This can then be used to more specifically direct diagnosis and further testing.
