摘要： A system for adjusting transmission power levels of transceivers in order to reduce crosstalk utilizes a transmitter and logic. The transmitter is configured to transmit signals to a customer transceiver over a first communication connection that is bound within a binder. The logic is configured to estimate a distance of a data path between the transmitter and the customer transceiver based on at least one signal communicated over the data path. The logic is further configured to adjust a transmission power level of the transmitter based on the estimated distance such that signals transmitted by the transmitter to the customer transceiver are spectrally compatible with signals transmitted from another transceiver over a second communication connection that is bound within the binder.

摘要： A network access device comprises a first line card, a second line card, and logic. The first line card has a first transceiver coupled to a first subscriber line, and the second line card has a second transceiver coupled to a second subscriber line. The logic is configured to switch communication from the first subscriber line to the second subscriber line in response to a detection of an error condition for communication occurring over the first subscriber line.

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： In a data communication system having a channel with time-varying impairments and further having a transmitter with a precoder, a method and apparatus for updating the precoder coefficients. The method and apparatus is based on the arrangement of a duplicate precoder and correction filter in the receiver, where the correction filter generates incremental coefficients. The incremental coefficients are sent via a back channel to the transmitter and added to the current values of the precoder coefficients. The method and apparatus provide DFE-like performance and do not have the delay problems associated with DFEs.

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： The present disclosure generally pertains to an arrayed media converter (AMC) that has an array of Wavelength Division Multiplexing-Passive Optical Network (WDM-PON) Optical Network Units (ONUs) for terminating an optical channel in the feeder or distribution portion of a telecommunication network. The ONU converts an optical signal from the optical channel into at least one electrical signal for transmission to a customer premises. Thus, the AMC serves as an interface between at least one WDM-PON link and at least one conductive connection, such as a twisted pair. In one exemplary embodiment, the AMC comprises a sealed housing that is environmentally hardened to protect the AMC from environmental conditions, including changes in weather. Such an AMC may be used to provide a robust, cost effective Fiber To The Curb (FTTC) solution, but the AMC may be used at other points within the network, if desired.
