A communication system, device and method for providing twisted pair multilink communications are provided. The system includes a first operator end terminal unit configured to couple to a first customer premises equipment (CPE) via a first twisted pair and configured to exchange first communications with the first CPE for transmission of a first part of traffic data of the first CPE over a first communication link on a first twisted pair. The system further includes a second operator end terminal unit configured to couple to a second CPE via a second twisted pair and configured to exchange second communications with the first CPE for transmission of a second part of traffic data of the first CPE over a second communication link that is a crosstalk link induced by the second twisted pair to the first twisted pair.

Method and apparatus for providing twisted pair multilink communications

A method of communicating using an optical line terminal (OLT), the method comprising acquiring encapsulated data by a digital subscriber line (DSL) physical media specific transmission convergence (PMS-TC) sublayer from a protocol specific transmission convergence (TPS-TC) sublayer, and framing the encapsulated data into a frame by the PMS-TC sublayer for transmission to a corresponding PMS-TC sublayer in a customer premises equipment (CPE).

Passive optical network digital subscriber line convergence architecture

An apparatus comprising a digital subscriber line (DSL) transmitter configured to transmit a discrete multi-tone (DMT) superframe comprising a sync frame and a data frame, wherein a time duration of the superframe is equal to at least a sum of a time duration of the sync frame and twice a time duration of the data frame, and turn off at least a portion of the DSL transmitter for a portion of the time duration of the superframe, wherein the portion of the time duration is no shorter than the duration of the data frame.

Symbol-gated discontinuous mode for efficient power management of digital subscriber line transceivers

An apparatus comprising a processor configured to determine a power management (PM) state from a plurality of PM states for a digital subscriber line (DSL) transceiver, wherein the plurality of PM states comprise a idle state, a full on state, and a low power state, wherein the full on state consumes more power than the low power state, wherein the low power state consumes more power than the idle state, wherein the low power state comprises at least one PM profile, and wherein the DSL transceiver supports a very high speed digital subscriber line 2 (VDSL2) data transmission protocol, and instruct the DSL transceiver to use the PM state.

Low complexity, optimized power management scheme for very high speed digital subscriber line transceivers 2

An apparatus comprising an artificial noise (AN) controller coupled to a digital subscriber line (DSL) transmitter and configured to adjust an AN level for a signal transmitted by the DSL transmitter, wherein the AN level is adjusted based on an actual signal to noise ratio (SNR) of the signal from the receiver to achieve a desired SNR for the signal. Also disclosed is a method comprising maintaining a data rate in a line at about a desired level by adjusting an AN level in a transmitted signal based on a SNR of a received signal.

Dynamic transmitter noise level adjustment for digital subscriber line systems

Techniques for establishing TTR indication in ADSL Annex C based communication systems are disclosed. The techniques enable, for example, hyperframe alignment and synchronized initialization procedures (e.g., G.hs).
