Abstract

During the development of Low Power Mode (LPM) (also known as L2 Mode) for DSL (Digital Subscriber Line) systems, it has become apparent that one of the most important issues is the impact on deployed legacy DSL systems. Legacy DSL systems are not capable of operating in the presence of large changes in crosstalk noise from neighbouring lines entering and exiting LPMs. For example, prior LPM methods at least do not assure that legacy lines will be protected to guarantee that no retrains will occur. These and other issues are addressed herein.

Claims (3)

1 . A method comprising:

transmitting or receiving, by a transceiver and prior to entering an L2 Mode, a message comprising a parameter indicating at least a minimum expected throughput after a first L2 exit step from the L2 Mode.

2 - 33 . (canceled)
