Rocking PNM

Hi everyone, we are going to give an update on rocking Proactive Network Maintenance (PNM) and full band capture (FBC).  New and exciting features in PNM that every cable operator needs.

This is episode 64 of Get Your Tech On, our show on All Things DOCSIS.  I’m Brady Volpe, Founder of The Volpe Firm and Nimble This. With us today is John Downey,  CMTS Technical Leader at Cisco Systems, welcome back John. Join us with special guest Larry Wolcott, PNM pioneer and guru, while we discuss some of the latest advancements in full band capture (FBC) that will help the cable industry use proactive network maintenance (PNM) to optimize outside plant operations.

In our Power Hour of Cable on All Things DOCSIS join us and drop your comments into the chat. 

To set the stage for the conversation, Larry is going to share some slides with us.

Overview of rocking PNM see YouTube video:

• Water and coaxial cable
• FBC – full band capture
• New features with FBC
  • FBC has been doing FBC for 10 years
  • FBC with PNM is like driving around with large spectrum analyzer in truck – on demand
  • 80 to 90% of operators have FBC in modems
  • Passive TDR
    • Fully occupied spectrum – as a TDR
    • micro reflections
    • standing wave – not just a standing wave
    • impedance cavity
    • not injecting any signal into the plant
• Water slows down the velocity of propagation – an electrical signal
• We determined that there was water in the line
• Great way to determine a issue outside of the home
• Replace the drop when needed – especially with covid
• Using cable modem to see the RF into the house
• RF from FBC – we can see the standing wave
• FDR is FBC if you use meters
• Determining between drop vs feeder is easy
• Water is in the mix – impact to subscribers
  • Pockets of water – trying to trace the electron – is as if trying to trace a ray of light thru water
  • Do a virtual sweep
  • Lift bucket and get immediate access
  • Use FBC as a sweep tool
  • Especially with RPDs sweep is very difficult
• Just look for FM ingress – forget LTE
• Water poured out of the connector
• Most of the time you do not see water
• Group delay implications
• Massive improvement to subscriber
• ICFR
• low frequency cannot jump and high frequency’s cannot swim
• frozen cable pops – tests run on water in cable
• Natural environment on cable freezing vs non-frozen
• Detection – water signature – common standing waves
• OFDM signal
• Mainline
