US 7,257,220 B1 · Method and system for providing extended reach of a digital subscriber line signal

Abstract

A method for providing extended reach of a digital subscriber line signal includes receiving an incoming DSL signal, splitting the DSL signal into separate voice and data signals, demodulating the data signal, requantizing the demodulated data signal, modulating the requantized data signal, amplifying the modulated requantized data signal and the voice signal, combining the amplified voice and data signal into a combined signal, and transmitting the combined signal.

Dependent claims

A method for providing greater reach of a DSL signal comprising:

receiving an incoming DSL signal including a data signal and a voice signal;
demodulating the data signal;
requantizing the demodulated data signal by determining a constellation associated with each bit of data in the modulated data signal and resetting the value of that bit to the value of the constellation to acquire underlying data in the data signal and transform the data signal into a regenerated form;
modulating the requantized data signal;
combining and amplifying the modulated requantized data signal and the voice signal;
and transmitting the amplified signal.

combine and amplify the first remodulated data signal and the first voice signal to produce a second outgoing data signal;
the second conditioning circuit being operable to:
receive a signal indicative of a second incoming DSL signal including a second data signal and a second voice signal;
