A digital subscriber line (xDSL) communication system (10) is disclosed that allows xDSL communication across a local loop.

The digital communication includes DSL (Digital Subscriber Line) communication.

The data port (308) is adapted to provide digital subscriber line (DSL) service to subscriber premises equipment.

The first VLAN tag identifies a DSL subscriber.

The UIP client (224) is located at the SL and is capable of deploying DSL capability on a single communication line.

An x digital subscriber line (xDSL) data transmission device is disclosed in the present invention. xDSL chipsets and a first chip are set in a line card.

An x digital subscriber line (xDSL) time synchronization method, apparatus and system are provided in present invention.

An optical network unit (22) for managing digital subscriber line (xDSL) connections (26/28) to a passive optical network (12).

An extended digital subscriber line (xDSL) system, a signal transmission method, a transmission apparatus and a receiving apparatus are provided by the present invention.

Systems and methods for mitigating the effects of self-FEXT within an xDSL system are described.

A digital subscriber line access multiplexer (506) is connected to the first digital subscriber line (502).

Digital Subscriber Line Access Multiplexer/Multi-Service Access Node.

The digital subscriber line access multiplexer (506) separates the digital subscriber channel from the ISDN channel (522).

A device parameters configuring method in a digital subscriber line access network, a digital subscriber line access system and a network device.

A modem for use in Digital Subscriber Line communications transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters.

A method of transforming a digital subscriber loop signal includes providing the digital subscriber loop signal; and increasing a gain of the digital subscriber loop signal with a digital subscriber loop repeater.

The falsified alteration was sent through a Digital Subscriber Line (DSL) or Digital Subscriber Loop – a family of technologies that provide internet access by transmitting digital data over the wires of a local telephone network.
