METHOD AND ARRANGEMENT FOR THE POWER MANAGEMENT OF A DIGITAL COMMUNICATION LINE

摘要

The present invention relates to a method and an arrangement for the power management of a digital communication line such as a digital subscriber line DSL (2201). A problem addressed by the invention is that the transitioning of the digital subscriber line (2201) from a low transmission power state to a high transmission power state can cause disturbance to adjacent lines. This problem is solved by the current invention by an access node AN (2100) that is arranged to step-wise increase the power state until the high transmission power state has been reached. The invention also comprises embodiments of monitoring and detecting traffic events that serve as triggers of the transitioning.
