  • Patent number: 10601463
    Abstract: Methods and systems are provided for telephone line access with crosstalk stability. A transceiver device coupled to a telephone line, bundled with other telephone lines in a telephone cable, may determine when another transceiver device connected to the telephone cable is estimating signal to noise ratio on another telephone line in the telephone cable, and may control communications over on the telephone line, the controlling including forcing a transmission on the telephone line based on the estimation of signal to noise ratio by the other transceiver device. The transmission may be forced on the telephone line when there is no data to send on the telephone line at a time when the other transceiver device estimates the signal to noise ratio. The forced transmission may be generated by modulating sub-carriers using a pseudo-random sequence generated with an initial seed different from initial seeds used by other transceiver devices.

  • Patent number: 9825666
    Abstract: The present disclosure includes systems and techniques relating to wired communication channels, such as telephone lines in a bundled telephone cable. In some implementations, a system includes telephone lines bundled together, electronic equipment at a first location includes a first transceiver device for each of the telephone lines, where each first transceiver device at the first location is configured to coordinate transmissions over a respective telephone line coupled with the first transceiver device; and second transceiver devices coupled respectively with the telephone lines at second locations, such that each second transceiver device is respectively paired with a first transceiver device at the first location; each pair of the first and second transceiver devices is configured to force transmission on a telephone line connecting the pair when another pair of the first and second transceiver devices estimates a signal to noise ratio on the telephone line connecting the other pair.
