Abstract: Mitigation of satellite interference is contemplated. The mitigation may include processing satellite transmissions to remove interferences based on an amount of signal overlap, such as to facilitate mitigating interferences resulting from satellite spacing and/or ground antenna dish size.

Abstract: A method for automatic discovery of a communication network including a hub, a plurality of termination devices, and a plurality of network elements. The method includes (a) associating respective geographic information with each termination device, (b) determining a respective distance of each termination device from the hub, (c) grouping, at least partially based on diagnostic information from the communication network, two or more of the plurality of termination devices sharing a common characteristic, (d) determining a topology of the communication network, and (e) determining a respective characteristic of at least one network element of the plurality of network elements.

Abstract: A method for comparing communication links in a communication network includes (a) obtaining first raw equalizer coefficients in a frequency domain, the first raw equalizer coefficients corresponding to a first communication link, (b) obtaining second raw equalizer coefficients in the frequency domain, the second raw equalizer coefficients corresponding to a second communication link, (c) removing time delay from the first raw equalizer coefficients to generate first corrected equalizer coefficients, (d) removing time delay from the second raw equalizer coefficients to generate second corrected equalizer coefficients, and (e) comparing the first corrected equalizer coefficients to the second corrected equalizer coefficients to determine a relationship between the first and second communication links.

Abstract: A system for detecting a failure along a transmission line of a cable plant is provided. The system includes a mobile vehicle configured to travel along a pathway substantially proximate to the cable plant along a span of the transmission line, and a transmitter disposed with the mobile vehicle. The transmitter is configured to emit (i) a test signal capable of ingressing the transmission line at a location of the failure, and (ii) an information signal containing location and velocity data of the mobile vehicle. The test signal is configured to provide phase shift and Doppler frequency information to a receiver operably connected to the transmission line at a location upstream from the location of the failure.

Abstract: Systems and methods provide for a network test that by capturing in-phase values of a reflected signal off a transmission medium or irregularity therein. The in-phase values are converted to time-domain, which is then halved and converted back to the frequency domain to identify calculated quadrature values associated with the measured in-phase values. The measured in-phase values and calculated quadrature values may be used to determine impedance reflection/transmission characteristics of transmission medium or an irregularity therein. The measured in-phase values and calculated quadrature values may be used to determine if the transmission medium is minimum phase.

Abstract: Facilitating echo cancellation within communication networks is contemplated, such as but not necessarily limited to facilitating echo cancellation within full-duplex (FDX) communication networks. The echo cancellation may optionally be performed with an echo canceller included as part of or otherwise associated with an FDX node used to facilitate interfacing signaling between a digital domain and an analog domain of a FDX or other communication network.

Abstract: A communication network includes a first electrical cable, a home network translation device, and a first termination device. The home network translation device is communicatively coupled between an optical cable and the first electrical cable, and the home network translation device is configured to translate data between an optical protocol on the optical cable and a home networking protocol on the first electrical cable. The first termination device is communicatively coupled to the first electrical cable and is configured to translate data between the home networking protocol on the first electrical cable and an additional protocol on an additional communication medium communicatively coupled to the first termination device.

Abstract: A method for transmitting a digital frame by an optical network unit in a digital communications network includes steps of arranging received data into a series of symbols, installing a primary cyclic prefix immediately preceding the series of symbols in time, and inserting individual ones of a plurality of secondary cyclic prefixes between each adjacent pair of symbols in the series of symbols. A length of each secondary cyclic prefix corresponds to a first duration shorter than an amount of time needed to turn on a laser of the optical network unit. The method further includes a step of providing to the optical network unit the digital frame. The digital frame includes the primary cyclic prefix, the plurality of secondary cyclic prefixes, and the series of symbols. The method further includes a step of modulating the provided digital frame by a laser of the optical network unit.
