Abstract
Methods, circuitries, and systems for transmitting data upstream between a first device and a second device and downstream between the second device and the first device are disclosed. A method includes determining an upstream crosstalk effect for an upstream channel and determining a downstream crosstalk effect for a downstream channel. The crosstalk effect includes near end crosstalk from a third device that is non-co-located with respect to the first device and the second device. A data rate of an upstream transmission or downstream transmission is adjusted based on the upstream crosstalk effect and the downstream crosstalk effect.
