Abstract
In one embodiment, a method includes communicating with a Digital Subscriber Line (DSL) transceiver unit through a first twisted pair that comprises a first plurality of wires, and communicating with the DSL, transceiver unit through a second twisted pair that comprises a second plurality of wires. A training procedure is implemented to receive first signals from the DSL transceiver unit through the first plurality of wires of the first twisted pair, and to send second signals to the DSL transceiver unit through the second plurality of wires of the second twisted pair.
Claims26
An apparatus, comprising:
- a first interface operable to communicate with a Digital Subscriber Line (DSL) transceiver unit through a first twisted pair, the first twisted pair comprising a first plurality of wires;
- a second interface operable to communicate with the DSL transceiver unit through a second twisted pair, the second twisted pair comprising a second plurality of wires;
- and
- logic embodied in one or more tangible media for execution and when executed operable to:
- receive a plurality of first signals from the DSL transceiver unit through the first plurality of wires of the first twisted pair;
- and
- send a plurality of second signals to the DSL transceiver unit through the second plurality of wires of the second twisted pair.
A method, comprising:
- communicating with a Digital Subscriber Line (DSL) transceiver unit through a first twisted pair, the first twisted pair comprising a first plurality of wires;
- communicating with the DSL transceiver unit through a second twisted pair, the second twisted pair comprising a second plurality of wires;
- and
- receiving a plurality of first signals from the DSL transceiver unit through the first plurality of wires of the first twisted pair;
- and
- sending a plurality of second signals to the DSL transceiver unit through the second plurality of wires of the second twisted pair.
A system, comprising:
- a central Digital Subscriber Line (DSL) transceiver unit;
- a remote DSL transceiver unit;
- a first twisted pair comprising a first plurality of wires, the first twisted pair coupled to the central DSL transceiver unit and the remote DSL transceiver unit;
- and
- a second twisted pair comprising a second plurality of wires, the second twisted pair coupled to the central DSL transceiver unit and the remote DSL transceiver unit;
- the central DSL transceiver unit operable to send a plurality of downstream signals to the remote DSL transceiver unit through the first plurality of wires;
- and
- the remote DSL transceiver unit operable to send a plurality of upstream signals to the central DSL transceiver unit through the second plurality of wires.
