Abstract:
Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a wired communications device involves including a frame boundary bit sequence and a random data sequence as a preamble of a bit stream, encoding the bit stream into an encoded bit stream, and transmitting the encoded bit stream using the wired communications device.
Abstract:
The present application relates to a transceiver, TX/RX PHY, and a method of operating the TX/RX PHY arranged for bi-directional data communication of a node with a counterpart node connected to in a point-to-point network using differential mode signaling over a single twisted-pair cable. A TX adjustment component is arranged in a TX path of the TX/RX PHY and configured to adjust a TX data communication signal generated by the TX/RX PHY for transmittal to the counterpart node. The TX adjustment component is further configured to accept information about a common mode signal detected on the single twisted-pair cable and to adjust the TX data communication signal to at least weaken the common mode signal occurring at the counterpart node in response to transmitting the TX data communication signal.
Abstract:
Systems and methods for operating a filter for echo cancellation are described. In one embodiment, a method for operating a filter for echo cancellation involves monitoring at least one of a filter coefficient of the filter and an echo cancellation error to generate a monitoring result and, in response to the monitoring result, adjusting at least one of delay elements and filter taps of the filter to vary an impulse response of the filter. Other embodiments are also described.
Abstract:
As consistent with one or more embodiments, electronic circuitry is characterized to provide an indication of susceptibility of the circuitry to error. As consistent with one or more embodiments, bits corresponding to a circuit component of a circuit design are evaluated using a software program that characterizes a hardware description language representing the circuit components and their interconnectivity. A noise power value is calculated for each bit, and bits are identified as being susceptible to data error based upon the noise power value and a signal-to-noise (SNR) ratio reference value. A characterization of the circuit components (e.g., a quality factor) is provided based upon a number of bits susceptible to data errors.

Abstract:
Embodiments of a method and a device are disclosed. In an embodiment, a method for performing physical layer operations in a communications network is disclosed. The method involves determining a desired error management mode for a receiver at a first network node, at the first network node, embedding an indication of the desired error management mode into a forward error correction (FEC) frame, and transmitting the FEC frame from the first network node. In an embodiment, embedding an indication of the desired error management mode into an FEC frame includes embedding an operations, administration, and management (OAM) word into the FEC frame to communicate the indication of the desired error management mode.
