  • Patent number: 12010261
    Abstract: Automatic testing/analysis of local loops of telecommunications networks includes obtaining bits-per-tone data for a local loop of a telecommunications network and generating a bit value string from the bits-per-tone data. The bit value string is then analyzed to determine whether it includes a bit pattern indicative of an impairment of the local loop. Further approaches for automatically testing local loops of telecommunications networks include obtaining attenuation data for multiple tones carried by the local loop and determining whether the attenuation data falls below thresholds for providing a service using the local loop.

  • Patent number: 12009966
    Abstract: An application or software of a cable modem provides reporting as to one or more issues associated with a reset of a cable modem (CM). Issues related to the upstream (US) link and/or downstream (DS) link of the multiple service operator (MSO) can cause a reboot of a CM coupled to the MSO network. While Data Over Cable Service Interface Specification (DOCSIS) defines various CM reset codes, these codes fail to identify whether the issue that the caused the reset of the CM related to the US link, the DS link or both. The provided system includes a CM for determining the cause of a reset of the CM as one or more reset codes that can be communicated or reported to the MSO so that the MSO has the information necessary to determine any issues or problems with the US link, the DS link or both.

  • Patent number: 11968290
    Abstract: Some embodiments are directed to a circuit compiling device for compiling a function into a binary circuit and a function evaluation device for evaluating a function using such a binary circuit. The binary circuit comprises conjunction subcircuits each computing a conjunction of function input bits and XOR subcircuits each computing a function output bit. Each function output bit may be represented as a sum of interpolation terms, the plurality of function input bits and the interpolation terms of the one or more function output bits together forming a plurality of interpolation terms. A conjunction subcircuit computes an interpolation term as a conjunction of two interpolation terms. A XOR subcircuit computes a function output bit as a XOR of interpolation terms. Thereby, the first interpolation term and second interpolation term are also used in XOR subcircuits, hence the binary circuit has a smaller number or likelihood of ineffective faults.

  • Patent number: 11916704
    Abstract: Techniques are described for pre-equalization at the demodulator of a satellite receiver terminal to compensate for forward link distortions. Some satellite channel filters can manifest distortions, such as asymmetric group delay response. Such distortions can conventionally force restriction of symbol rate only to the portion of the channel bandwidth having a symmetric filter response. Embodiments include a pre-equalizer in the demodulation path that filters received downlink communications based on a set of pre-equalizer filter coefficients computed to at least partially compensate for the channel filter distortions. Some embodiments support updating the filter coefficients based on channel reassignments, and/or dynamically updating the filter coefficients based on detecting and exploiting pre-equalization frames. The pre-equalized sample stream can facilitate reliable decoding by the demodulator with an appreciably increased symbol rate and correspondingly increased forward link capacity.

    Abstract: Aspects of the embodiments are directed to systems and methods for performing link training using stored and retrieved equalization parameters obtained from a previous equalization procedure. As part of a link training sequence, links interconnecting an upstream port with a downstream port and with any intervening retimers, can undergo an equalization procedure. The equalization parameter values from each system component, including the upstream port, downstream port, and retimer(s) can be stored in a nonvolatile memory. During a subsequent link training process, the equalization parameter values stored in the nonvolatile memory can be written to registers associated with the upstream port, downstream port, and retimer(s) to be used to operate the interconnecting links. The equalization parameter values can be used instead of performing a new equalization procedure or can be used as a starting point to reduce latency associated with equalization procedures.

    Abstract: Digital approximate multipliers (aMULT) utilizing interpolative apparatuses, circuits, and methods are described in this disclosure. The disclosed aMULT interpolative methods can be arranged or programmed to operate asynchronously and or synchronously. For applications where less precision is acceptable, fewer interpolations can yield less precise multiplication results, while such approximate multiplication can be computed faster and at lower power consumption. Conversely, for applications where higher precision is required, more interpolations can generate more precise multiplication results.
