摘要： Methods, systems, and apparatus for crosstalk avoidance in a telecommunications network are disclosed. In one aspect a method includes determining, by a network element and for each vectoring group from multiple vectoring groups, a transmission load of the vectoring group based on transmission loads of links within the vectoring group; allocating, by the network element, a different transmission interval to each vectoring group from the multiple vectoring groups based on the transmission load of the vectoring group and transmission loads of other vectoring groups in the multiple vectoring groups; and transmitting, during each different transmission interval, at least a portion of the transmission load of the vectoring group that was allocated the different transmission interval.

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： A time-division duplexing (TDD) system reduces crosstalk associated with signals communicated by coordinated dynamic time assignment (cDTA) transceivers. In some embodiments, the TDD system has both cDTA transceivers and legacy transceivers. Based on the dynamic allocation of downstream and upstream timeslots for the cDTA transceivers, timeslots for the legacy transceivers are selectively muted in an effort to limit the amount of near-end crosstalk (NEXT) that occurs in the TDD system. Thus, subscriber lines coupled to both cDTA transceivers and legacy transceivers may be bound within the same binder without significantly increasing crosstalk to unacceptable levels.

摘要： Methods, systems, and apparatus for determining a loop length of a link. In some implementations, a method includes obtaining timing information for bi-directional communications over a link that is being initialized or is in showtime and determining a loop length of the link using the timing information while the link is being initialized or is in showtime. The timing information used while the link is being initialized can include a time value used to align data transmissions over the link. The timing information used while the link is in showtime can include times at which time synchronization events occur on the link while the link is in showtime.
