Abstract
Provided herein are methods and systems for a digital subscriber line protocol that does not require amplitude modulation, as well as methods and systems for such a protocol that can be used in combination with amplitude-modulation techniques to provide superior broadband DSL capabilities.
Claims25
A method of providing digital subscriber line communications, comprising:
- generating a signal of a plurality of tones, the variation in tones producing a change in the phase of the signal;
- transmitting the signal over a communications facility;
- measuring a characteristic of the received signal;
- and
- determining a value of a data bit based on the value of the measured characteristic.

A method of providing a DSL transmitter, comprising:
- providing a facility for receiving an incoming data signal;
- providing an encoding facility for encoding the signal;
- providing a data facility for assigning frequencies based on the incoming data signal;
- providing a frequency generator for generating the assigned frequencies, wherein frequencies are assigned to produce variations in the characteristics of the generated signal, the characteristics selected from the group consisting of peak phase, peak-to-peak time, flat time, off time, event time and a ratio of at least two of them;
- and
- providing a facility for sending the generated frequencies to a communications facility.
