  • Method and apparatus for generating a metering pulse
    Patent number: 7991133
    Abstract: In one embodiment, a subscriber line interface circuit includes circuitry to generate metering pulses for insertion onto a subscriber line. The circuitry includes an audio path and a pulse metering path, where the pulse metering path includes a metering generator to generate a digital sine wave from a plurality of stored values, a first interpolator to interpolate the digital sine wave, a filter to filter the interpolated digital sine wave, and a second interpolator to interpolate the filtered interpolated digital sine wave.
    Type: Grant
    Filed: September 29, 2005
    Date of Patent: August 2, 2011
    Assignee: Silicon Laboratories Inc.
    Inventors: Michael Mills, Marius Goldenberg, Yan Zhou, Jeffrey Whaley
  • Pulse metering architecture
    Patent number: 7280062
    Abstract: In one embodiment, a subscriber line interface circuit includes circuitry to generate metering pulses for insertion onto a subscriber line. The circuitry includes a cascaded digital-to-analog converter (DAC) structure including a first DAC to convert a digital sine wave into an analog representation, a second DAC to multiply the analog representation with a ramp value to obtain an unscaled output, and a third DAC to multiply the unscaled output with a gain value to generate a metering pulse.

  • Method and apparatus to provide selective status information for communications channel(s)
    Publication number: 20060067264
    Abstract: An integrated circuit maintains status information for a communications channel. The integrated circuit selects a portion of the status information maintained for the communications channel. The integrated circuit repeatedly transmits the selected portion of status information over a time-division multiplexed channel to a host.
