Abstract
A system and method for providing a service over a repeatered link that couples a service provider transceiver to a remote modem, the method includes: computing, for each frequency bin out of multiple frequency bins of a spectrum, a level of far-end cross-talk (FEXT) interference that is generated to a network-side receiver of a frequency division multiplexing (FDM) discrete multi tone (DMT) repeater by a service provider transmitter that provides an FDM DMT service that is supported by the FDM DMT repeater; computing, for each frequency bins out of the multiple frequency bins, a highest allowable transmit power level of a customer-side transmitter of the FDM DMT repeater that generates to the network-side receiver of the FDM DMT repeater a cross-talk interference that does not exceed a level of FEXT interference that is generated to the network-side receiver of the FDM DMT repeater by the service provider transmitter.
