Abstract: 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.
