Welcome, Brady Volpe and John Downey will dive into the world of UTSC (Upstream Triggered Spectrum Capture) for return path monitoring in a DAA world, how cable operators can harness these game-changing technologies. Join us as we discuss the latest updates on UTSC and PNM. Whether you’re a cable operator looking to stay ahead of the competition or a curious tech enthusiast eager to learn about the next generation of broadband technology, this video is a must-watch! this video is a must-watch!

Brady Volpe and special guest John Downey of Cisco we’ll be discussing:

UTSC

What is UTSC? – Upstream Triggered Spectrum Capture

Return Path Monitoring for DAA

UTSC

  • Upstream Triggered Spectrum Capture (UTSC)
  • Included in the DOCSIS specifications
  • Uses SNMP to configure the CCAP (CMTS) to start an FFT in the RPD
  • The RPD sends back return spectrum data to either:
  • The CCAP, which relays this data to the PNM server or
  • The RPD will send the data directly to the PNM server
  • The PNM server converts the raw data into a spectrum display

Current Status of UTSC

  • 5x traces / second, but should be able to achieve 10x traces / second
  • Most vendors currently support free run mode
  • Future we should see:
  • Filtering on MAC / SID
  • Burst noise detection
  • Active probe & Quiet probe
  • Even the ability to turn off subcarriers & see noise under sub-carriers

Cool features of Software + UTSC

  • Sky is unlimited as we can overlay lots of stats
  • Overlay MER, Pre & Post FEC
  • Mobile apps
  • Plot over time

You went high-split? (204 MHz). So does UTSC

  • And you can see potential noise issues before you deploy
  • Pre-test your high frequency spectrum
