ABSTRACT:
A system for verifying spectral compatibility of a communication system that utilizes at least one digital subscriber line protocol includes a plurality of digital subscriber line access multiplexers and a communications channel coupling the plurality of digital subscriber line access multiplexers. Each digital subscriber line access multiplexer is operable to transmit and receive at least one message over the communications channel. The message comprises information related to a training of a digital subscriber line modem by a carrier.
