Abstract:
1. A method for training a line driver in a communication system; said line driver being coupled with a communication line at a connection locus; said communication line being configured for communicating with subscriber equipment at a subscriber locus distal from said connection locus using at least one selected communication tone-set of a plurality of communication tone-sets; the method comprising the steps of: determining a first noise value expected to be experienced on said communication line for present communications, wherein the first noise value is due at least in part to operations of other communication lines terminated in said connection locus; determining a second noise value expected to be experienced on said communication line from other communication lines subsequently terminated at said connection locus; evaluating quality of said communication line considering both the first noise value and the second noise value; said quality of said communication line being acceptable when the first noise value and the second noise value are collectively within a predetermined value range.
