    摘要： The present invention provides a method and a device for line initialization. In the method, first, a first precoding matrix needed 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 needed 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： The present invention relates generally to a customer premises based method for detecting the presence of a micro-filter on a VDSL connection. According to certain aspects, the method uses SELT test signals that are transmitted from the customer premises modem and whose associated echo signals are received and analyzed by the customer premises modem, According to further aspects, specific characteristics of several different SELT signals are utilized to robustly and effectively determine the presence or absence of the micro-filter/splitter.

    摘要： A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by a tone communicated by any member of the vector group. Further, the line cards are coupled to one another via a data connection across which a vectoring stream carrying vectoring information from one line card to the next. The bandwidth of the vectoring stream is reduced by dynamically adjusting time slots of the vectoring stream based on bit loading for the communicated tones.
