Abstract:
A digital subscriber line arrangement includes a first downstream Access Node (AN) modem, a first upstream Customer Premises Equipment (CPE) modem, a second AN modem, a second CPE modem and first and second metallic pairs connected between the first and second modems, respectively. The first AN modem includes a length estimation module and a PSD mask selection module which together with a PSD mask store operate to select upstream and downstream PSD masks for use by the first CPE modem and the first AN modem, respectively. Selection of the masks depends upon the estimated line length and the manner in which neighboring communication link is operating. Additionally, a central controller is operable to perform selection or generation of such masks in a similar manner when centralized control over the PSD mask generation is desired.

Claim (Index 6):
A central controller device for generating and communicating a power spectral density (PSD) mask to a (PSD) controlled modem for use within a first communication link, the first communication link comprising a first pair of metallic wires and communicating first modems connected at each end thereof, the first pair of metallic wires having an access network end and a remote end and the communicating modems comprising a first access network side modem connected to the access network end of the first pair of metallic wires and a first remote side modem connected to the remote end of the first pair of metallic wires, wherein the controlled modem is one of the communicating first modems and is a discrete multitone modulation modem operating using time division duplexing and is operable to employ a first set of tones whose frequencies fall within a first operational frequency range, wherein the first communication link is operated within the vicinity of at least a second communication link comprising a second pair of metallic wires and communicating second modems connected at each end thereof, the second modems of the second communication link being discrete multitone modulation modems operating using frequency division duplexing and being operable to employ a second set of tones whose frequencies fall within a second operational range, wherein the first and second communication links are physically located sufficiently closely together for at least a part of their extent, and are operable to employ operational frequency ranges overlapping to a sufficient extent, and at a sufficiently high PSD, that there is a possibility of the controlled modem generating a transmission signal which causes undesirable near end crosstalk interference to the second communication link, the central controller device comprising:\n an interface to a records database for obtaining an estimate of a length of the first pair of metallic wires; a PSD mask generator or selector for generating or selecting a PSD mask, wherein the generated or selected PSD mask depends upon the estimated length of the first pair of metallic wires; and a transmitter for transmitting the generated or selected PSD mask to the controlled modem, for use by a signal shaper within the controlled modem for controlling power of transmissions from the controlled modem, by frequency, in accordance with the transmitted generated or selected PSD mask.
