DOCSIS Softwarization in a DAA and Virtualized Network

Mia Colabrese2022-10-24T10:57:55-04:00September 12th, 2022|

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

Understanding Cable Network RF Return Path Signal Levels and Balancing

Mia Colabrese2022-08-17T12:43:19-04:00August 17th, 2022|

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.

Full Band Capture Troubleshooting by Impairment Type

Mia Colabrese2022-07-20T14:29:56-04:00July 19th, 2022|

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.
