Brady Volpe and John Downey discuss what you can expect to get out of DOCSIS 3.1 cable modem today. How many modems can transmit in a 6.4 MHz OFDMA channel? How much life is in the DOCSIS 3.1 modem for your network. Also a SCTE EXPO overview and wrap. What is Possible with a DOCSIS 3.1 Modem Today? This is episode 85 of Get Your Tech On, our show on All Things DOCSIS. Our topic for today is What is Possible with a DOCSIS 3.1 Modem, an
As technology continues to evolve, DOCSIS Softwarization in a DAA and virtualized network is a necessity. What does this mean exactly? Join Brady Volpe with special guest Tadeusz Ciesielski, Chief Technology and Innovation Officer at Falcon V Systems as they discuss the evolving technology hurdles cable operators face as DOCSIS hardware becomes increasingly more DOCSIS software. Management of critical DOCSIS 3.1 and DOCSIS 4.0 infrastructure requires software orchestration. Further, virtualization and virtual CMTSs (vCMTS) can benefit from rapid software deployment cycles. Aligning to these changes requires operational
Brady Volpe and John Downey discuss the theory of operation of return path signal levels in the return path. Why does the transmit power increase, rather than decrease like the downstream? How do two way splitters impact upstream and downstream signal levels? Why is the return always higher than the value the of tap +20? And more examples and discussion on the impact of RF in the cable network and troubleshooting.

In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey (of Cisco) discuss portions of the document "Understanding Cable Network RF Spectrum Displays". This document, created by CableLabs and SCTE Working Group 7 (WG7) is a masterpiece of understanding full band capture (FBC) and the impairments found with FBC. We have covered FBC before, but we have not gotten deep into each impairment type. We go much further in this episode and give you a preview into the soon to be release WG7 document.
In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey (of Cisco) answer viewers questions about upstream SNR / Diplex filters / OFDMA / ICFR Want to know what might be interesting and useful to you? Join in on the discussion and ask questions in the chat in another power hour of cable and the discussion on all things DOCSIS and beyond. Give us a thumbs up if you like her content. The discussion is on all things DOCSIS. Tips, suggestions and recommendations. Another
In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey (of Cisco) talk the latest technologies and trends in the Cable industry, especially around DOCSIS 3.1 and 4.0. We will be focused on key topics from Light Readings Next-Gen Technologies & Strategies. Want to know what might be interesting and useful to you?

In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey (of Cisco) discuss Upstream Transmit Power with OFDMA and elaborate why a cable modem’s transmit power is extremely important. It not only determines if the cable modem will be able to come online and register with the CMTS (cable modem termination system) but obtaining the optimal transmit power will make or break the subscriber’s quality of experience (QoE). A DOCSIS 3.1 cable modem’s transmit power introduces some new considerations which are discussed in this
In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey (of Cisco) elaborate on how to use PNM tools to identify house amps, Cable Modems with filter issues, etc. So houses can be identified with incompatible filters for intended UpStream spectrum deployments.

In this episode Brady Volpe of Nimble This and The Volpe Firm, discusses PTP clocks with subject matter experts Jim Olsen from Microchip and Rob Jodrie from Syncworks. This discussion includes a very high level break down of PTP profiles and why you should care? The evolution of PTP, Boundary clocks, best practices and things to look out for. You may think this is not a big topic but this is something that impacts all operators big, medium or small when deploying distributed access architecture (DAA) such as
