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.

1. A first communication node configured to communicate with at least one second communication node over at least one operational digital communication line, wherein the first communication node comprises:
a traffic event monitor comprising a call control message intercept unit that monitors received call control messages, wherein the traffic event monitor is configured to:
monitor traffic events, anddetect a selected traffic event, and a power mode control unit configured to send to the second communication node, in response to detection of the selected traffic event, a plurality of requests to increase the transmission power of the at least one operational digital communication line in the first communication node in a series of steps from a low transmission power state to a high transmission power state in the digital communication line.
