SCTE EXPO Highlights – What Rocked

This is episode 67 of Get Your Tech On, our show on All Things DOCSIS.  I’m Brady Volpe, Founder of The Volpe Firm and Nimble This.

Join in the conversation with Brady Volpe as he explores the many ways cable operators can benefit from PNM and services. With John Downey CMTS Technical Leader at Cisco.

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

Overview:

• Brain Teaser
• SCTE EXPO discussion – sessions
• Overview
  • Live Chat was great
  • Attend multiple sessions at once if you wanted
  • Better then being stuck in a session you didn’t want to watch
  • Reply – fast forward thru parts we didn’t like
  • Confusion on sessions – logistical issues
  • Virtual booth was difficult
  • Q&A – Moderators sometimes had issues understanding how to do certain thing
  • Q&A questions could be up voted
  • Virtual experience was great for technical sessions
  • Pre-made videos PNM Live – very positive
• Content
  • 10G, FDD, EXD etc
  • Lots of Covid
  • There was some good feedback on capacity problems
  • Several systems were overbuilt – due to competition
    • The competition helped us be ready for the pandemic due to pressure
• New Tech
  • Surprising – NDX – 1948 – 72 years into cable and still developing new stuff
    • Connector by Amphenol
    • Ground connection first
    • USB – Universal Serial Bus – Oxymoron
  • Very little New Tech was released or announced
  • Technetix showed there solution – new way of looking at things
  • Comcast Octave – PMA – AI – virtualized CMTS – ?
  • Little meat and potatoes
• Question 1 – from the chat room from Alaska – If we were to change a node to a 85 MHz return and not change the duplex filters right away, will the cable modems have issues?
  • Micro-reflections
  • We aren’t talking about the effect on the Cable Modem
  • DAA nodes recommendations – or EDR
• Question 2 – can you just replace some nodes? People off the node would get the full 85MHz?
  • Slow migrations to 85 MHz – 8 channel bonding
  • But House amps only to 42 MHz – 4 channel bonding
  • Node plus zero – Node plus one – 8 channel bonding or OFDMA with DOCSIS 3.1
  • Run SCQAM
  • Could work but were you don’t have 85MHz those modems will be in partial mode
  • Pros and Cons
  • Bonding group
  • 3dB drop in transmit power
  • Load balance
  • Don’t put 10 carrier QAM above 42
  • DOCSIS 3.1 – cherry pick the cable modem placement
  • OFDMA Channel drop IUC – or drop to partial mode
  • Step attenuator
• Apple big announcement – 5G
  • There isn’t a lot of 5G out there
  • Apple partnered with Verzion
  • Play to push 5G
  • 5G doesn’t go thru walls
  • 5G competition
  • 5G into cable modems?
  • Country specific
  • Wired Broadband
  • Telecom from Germany – share some frequencies but they don’t have 5G right now in Germany
• Coming Up
  • ANGACOM
  • SCTE EXPO Atlanta
  • Next show on Powering
• Question – from NY – LLX for 5G backhaul
  • Very short timing in DOCSIS
  • Need a nice hand off
  • Bandwidth report – CMTS needs to understand it’s 5G
  • Tight integration between cable modem and 5G
  • John Chapman did a great example – did the math
  • DOCSIS and Cable can handle 5G
