Abstract
A method, a system, and a device for power adjustment are provided. The method includes: determining whether transmission power of a line needs adjustment according to feedback errors during a training procedure of a Vectored-Digital Subscriber Line (Vectored-DSL) filter; and adjusting the transmission power when the transmission power of the line needs adjustment. By automatically determining whether the transmission power needs adjustment during a training procedure of a precoder or canceller, and adjusting the transmission power automatically when the transmission power needs adjustment, interference to other subscribers caused by the precoder or canceller during the training procedure is reduced, and call drops of the other subscribers are prevented.
