摘要： Methods, systems, and apparatus for crosstalk avoidance in a telecommunications network are disclosed. In one aspect a telecommunications device includes a transceiver and a vectoring engine coupled to the transceiver. The vectoring engine can include a vectoring processor and vectoring control entity (e.g., apparatus). The vectoring engine is configured to instruct the transceiver to transmit, over a given line pair of a given vectoring group, initialization symbols at one or more configurable locations of a Time-Division Duplex (TDD) frame. For example, the vectoring engine can instruct the transceiver to transmit the initialization symbols beginning at a first symbol time following transmission, over other line pairs of the given vectoring group, of a Robust Management Channel (RMC) symbol.

摘要： There is provided mitigation of disconnect events in a vectoring based digital subscriber line, DSL, system. A method performed by a digital subscriber line access multiplexer,DSLAM, comprises detecting a loss of signal or disconnect event of a line in a vectored group of DSL lines,the loss of signal or disconnect event causing a negative impact on the DSL system. The method further comprises detecting a change in at least one downstream, DS, crosstalk coefficient of at least one line in said vectored group of DSL lines. The method further comprises determining a magnitude of said change. The method further comprises determining where the loss of signal or disconnect event has occurred by processing precoding coefficients of the vectored group of DSL lines. The method further comprises determining,on basis of the determined magnitude and where the loss of signal or disconnect event has occurred, an action to be performed by the DSLAM so as to mitigate for said negative impact.

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 active transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by an active transceiver that is a member of the vectoring group. Further, the line cards are coupled to one another via a ring connection across which vectoring information is passed from one line card to the next. In the event of a failure of one of the line cards, the failed card is bypassed by the vectoring stream so that the operational line cards can continue crosstalk vectoring operations despite such failure.

摘要： Apparatuses and methods for analysing at least one characteristic of a test signal coupled out from one of a plurality of cable lines by a coupling unit to determine whether that test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines. The determination of whether the test signal has propagated directly to the coupling unit via a single cable line or has propagated indirectly to the coupling unit via one or more coupling paths between different cable lines, may advantageously be used for operational or diagnostic purposes, e.g. to identify interconnections between ports in a network.
