Upstream Triggered Spectrum Capture: Lessons Learned from Deployment at Scale          

  • Examining the evolution of Upstream Triggered Spectrum Capture (UTSC) tools and exploring aspects of:
    • Fast Fourier Transform (FFT)
    • Strategies for signal/noise classification
    • Forward Error Correction (FEC) rates
    • Modulation Error Ratio (MER)
    • Heatmap displays
  • Exploring the possibility of using Artificial Intelligence (AI) and Machine Learning (ML), and correlation to Upstream Data Analyzer (UDA) events
  • Lessons learned: Insights and recommendations

Smart Amplifier Ingress Noise Localization – An Integrated Solution Leveraging PNM         

  • Examining SCTE 279 as a standard for a new Smart Amplifier and SCTE 283 as an associated information model providing a number of monitoring and control functions
  • Leveraging the integration of PNM Upstream Triggered Spectrum Capture, HFC plant topology data, and existing standalone wink switches managed by an SCTE 283 compliant interface to localize ingress noise events
  • Examining and meeting the challengeof implementing these solution when considering intermittent and short-lived noise bursts, HFC plant topology discovery, and the impact on cable modems related to available transmit headroom
