Abstract
A method for communicating at least one of the hook state and associated in line filter indication from the ADSL Transceiver Unit-Remote Side to the ADSL Transceiver Unit-Central Office, or vice versa, for improving the performance of splitterless ADSL systems. This information is used to determine robust bits and gain allocation during startup, and to correct the profile selection during fast retrain.
