Abstract:
A method of simultaneously transmitting data over a plurality of subscriber lines extending between a shared device and a respective plurality of remote devices using a symbol-based discrete multi-tone transmission scheme, the method comprising:training each connection over each subscriber line extending between a shared device and a respective plurality of remote devices using a symbol-based discrete multi-tone transmission scheme to provide subscriber line specific information for each subscriber line; transmitting and receiving information over each subscriber line extending between a shared device and a respective plurality of remote devices using a symbol-based discrete multi-tone transmission scheme utilizing the corresponding subscriber line specific information; and transmitting to each remote device a destination code within a first group of frequency bands and modulated data within a second group of frequency bands different from the first group of frequency bands, wherein bits transmitted in each of the frequency bands in the second group of frequency bands are selected for a subscriber line connected to a remote device having the destination code within the first group frequency band.
