Systems, methods and computer program products are provided for simultaneously transmitting data over a plurality of subscriber lines, such as twisted pair telephone wires, extending between a shared device and a respective plurality of remote devices using a symbol-based discrete multi-tone transmission scheme. 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, are transmitted from the shared device to the remote devices. The second group of frequency bands is selected for a subscriber line connected to a remote device having the destination code within the first group of frequency bands. A number of bits transmitted within each of the frequency bands in the second group of frequency bands for a remote device is selected during a communication handshake between the remote device and the shared device by probing a subscriber line connected to the remote device to determine data rates that can be supported by the subscriber line at each of a plurality of frequency bands.
