Methods and devices are provided for estimating crosstalk from a legacy line to a vectored line.

Crosstalk mitigation

A sequence of symbols is received on a first channel. A noise contribution of a given synchronization symbol is estimated; a reference noise contribution of at least one further symbol is estimated. Based on the noise contribution and further based on the reference noise contribution the given synchronization symbol is selectively considered when determining a coupling coefficient of crosstalk between the first channel and a second channel.

Selective channel estimation

Described herein are systems, apparatuses, and methods relating to a power-saving state or power-saving mode to facilitate clock synchronization between the two transceiver units and/or updating of DSL operation parameters during the power-saving state.
