摘要： A communication system and method adaptively control frequency ranges of a pair of interconnected transceivers in an effort to enhance the data rate in one direction. In this regard, a full duplex communication session is established between a first transceiver and a second transceiver. Signals having frequencies within an overlapping bandwidth are communicated between the first and second transceivers during a data phase. A transmission capacity of one of the transceivers is determined based on the communicated signals, and a comparison between this transmission capacity and a specified transmission capacity for the one transceiver is performed. A portion of the overlapping bandwidth is adaptively selected based on the comparison, and the one transceiver is prevented from transmitting signals having frequencies within the selected portion of the bandwidth during the data phase.

摘要： The range of digital data communication services, such as a basic rate 2B1Q ISDN channel, to customer premises located beyond the industry standard achievable range of a two-wire loop can be extended by increasing the capacity of the ISDN line code from two information bits per symbol to three information bits per symbol, so as to reduce the effective symbol rate, which is error correction encoded to an effective 4B1H line code for defining a sixteen level PAM signal waveform, and employing enhanced low signal-to-noise ratio signal processing techniques in both the transmitter and receiver to accommodate the increased insertion loss of the two-wire line resulting from its extended length. Such enhanced low signal-to-noise ratio signal processing techniques include a Tomlinson precoder in the transmitter, and an adaptive linear equalizer and a module unit in the receiver.

摘要： A limited search variant of the fixed delay tree search detector is used to recover digital signals corrupted with intersymbol interference and additive noise. The limited search algorithm uses a variant of an equalizer decision device--a simple slicer--to reduce the number of paths that are considered by the tree search detector from M.sup.D+1 to either D+1 or 2.sup.D+1 paths, thereby significantly reducing the complexity of the tree-search detector. This limited search detector enjoys negligible loss in performance, compared with that of a full fixed delay tree search.

摘要： A jitter/wander reduction circuit is provided for a desynchronizer deriving an output clock signal from an independent clock signal and phase adjustment signals. Phase adjustment signals relate to a deviation of the independent clock signal from an input clock signal. The circuit includes a frequency offset estimation circuit receiving phase adjustment signals and providing a frequency offset estimation signal. A phase controller receives the frequency offset estimation signal, provides a feedback signal to the frequency offset estimation circuit, and provides a phase difference signal. A clock generator circuit receives the independent clock signal and the phase difference signal. The independent clock signal is adjusted based on the phase difference signal to provide an output clock signal.

摘要： The present disclosure generally pertains to systems and methods for communicating data. In one exemplary embodiment, a system has a high-speed channel, such as an optical fiber, between a network facility, such as a central office (CO), and a first intermediate point between the network facility and a plurality of customer premises (CP). Digital communication links, such as DSL links, are used to carry data between the first intermediate point, such as a feeder distribution interface (FDI), and a second intermediate point, such as the Distribution Point (DP). Non-shared links may then carry the data from the second intermediate point to the CPs. The links between the two intermediate points are bonded to create a high-speed, shared data channel that permits peak data rates much greater than what would be achievable without bonding. In some embodiments, multicast data flows may be prioritized and transmitted across a set of connections to each of the intermediate points. In addition, it is possible to power components at the intermediate points from one or more of the CPs.

摘要： A communication system has a trunk extending from a network facility, such as a central office, with a plurality of distribution points positioned along the trunk. Each leg of the trunk defines a shared channel that permits peak data rates much greater than what would be achievable without channel sharing. As an example, the connections of each respective trunk leg may be bonded. Further, the same modulation format and crosstalk vectoring are used for each leg of the trunk. The crosstalk vectoring cancels both far-end crosstalk (FEXT) that couples between connections of a given trunk leg and crossover crosstalk that couples between one trunk leg and another. In addition, logic determines an amount of excess capacity available for each leg of the trunk and controls error correction based on the determined excess capacity.

摘要： A communication system comprises a plurality of line cards having transceivers coupled to a plurality of subscriber lines. Each line card has at least one transceiver within the same vectoring group, and each line card also has vector logic capable of cancelling crosstalk induced by a tone communicated by any member of the vector group. Further, the line cards are coupled to one another via a data connection across which a vectoring stream carrying vectoring information from one line card to the next. The bandwidth of the vectoring stream is reduced by dynamically adjusting time slots of the vectoring stream based on bit loading for the communicated tones.

摘要： An optical communication system comprises a network interface device (NID) having a media converter coupled to an optical fiber of a passive optical network (PON). The media converter converts optical signals from the PON into electrical signals for communication across at least one non-optical channel, such as a conductive or wireless connection, to customer premises equipment (CPE), such as a residential gateway or other customer premises (CP) device. Rather than implementing an optical media access control (optical MAC) layer in the NID, an optical MAC layer for handling PON protocols and management is implemented by the CPE, thereby effectively extending the customer end of the PON across at least one non-optical connection to the CPE. By implementing the optical MAC layer at the CPE, the complexity of the NID is reduced thereby lowering the cost of the NID. In one embodiment, in an effort to further reduce the complexity of the NID, the optical MAC layer is configured to control a laser-on state of an optical transmitter in the NID.

摘要： A system for scaling vectored DSLAM deployments has a DSLAM interfaced with a cross-connect apparatus. The DSLAM receives POTS signals from at least one bridge connection assembly. When a DSLAM is added at the cross-connect facility, at least one connector of the bridge connection assembly is disconnected from an existing DSLAM and is interfaced with the newly-added DSLAM. By moving the connector to the newly-added DSLAM, a batch of downstream distribution pairs (which are preferably bound by a single distribution cable) are effectively moved from the existing DSLAM to the new DSLAM without having to reconfigure the jumpers of the cross-connect apparatus. Accordingly, it is possible to scale the cross-connect facility to any number of vectored DSLAMs while limiting vector group sizes, thereby reducing the complexity of vectoring operations, without having to perform complex reconfigurations of the cross-connect apparatus.
