ABSTRACT:
A method and system of the present inventions are directed to selecting an optimal mode for ADSL operation based near/far end modem capability, loop length and capacity in the upper bands of modes of operation. A method for switching among a plurality of modes for ADSL modem operation may include the steps of determining a far end modem's capability for supporting one or more of a base mode, a first mode and a second mode; determining a loop length between a near end modem and the far end modem; determining a capacity in an upper band of the first mode and the second mode; and selecting an appropriate mode based on a combination of the far end modem's capability, the loop length and the capacity in the upper band.
