Interpreting Full Band Capture and RxMER

Mia Colabrese2021-09-03T10:44:50-04:00September 3rd, 2021|

In this episode Brady Volpe of Nimble This and The Volpe Firm, and John Downey of Cisco discuss interpreting Full Band Capture (FBC) and RxMER which is the MER of the subcarriers in the OFDM channel. Cable is a technology business and we seem to always come up with new terms and new things to understand and interpret. FBC has been around now but still not everyone knows what it means and how to understand it correctly. RxMER is a bit newer but can still be mysterious

DOCSIS is Green (full length). Shorter and cleaner version is seen in Broadband Library DOCSIS Going Green. The simplest solution is almost always the best. Through technological advancements we can do more with less. There are important discussions happening about green initiatives in our industry. Usually on the consumer electronics side. According to the NCTA “Cable operators, video programmers, equipment manufacturers, research labs and others are now providing a more energy efficient experience that is saving consumers millions of dollars in energy bills and preventing millions of metric tons of

In this episode Brady and John discuss what happens to an impaired DOCSIS Primary channel & ANGA COM highlights. When an impaired DOCSIS Primary channel occurs, do to one ore more impairment, how does it impact other DOCSIS channels? Primary being a type of "management" SC-QAM channel. Does it make a difference? We also cover the top content from the ANGA COM show. Didn't have time to watch all of the ANGA COM show material. No problem.

Machine Learning and PNM

Mia Colabrese2021-08-13T08:43:30-04:00June 4th, 2021|

Machine Learning and PNM Yes, it’s real and yes, it’s deployed and working! The day has arrived, Skynet is here! [1]. Fortunately, no to Skynet and in more good news our machines are in the cable plant and they are learning. They have been deployed into the cable world and they are finding the nasty impairments we knew were there. Machine learning and PNM are making the technician’s job easier on many levels. It’s much easier to find the impairments, it’s significantly easier for technicians to know what

Recommendations to resolving DOCSIS 3.1 cable modems crashing with OFDMA

Mia Colabrese2021-06-03T12:49:12-04:00June 3rd, 2021|

Recommendations to resolving DOCSIS 3.1 cable modems crashing with OFDMA Place OFDMA channels above 42 MHz: For those fortunate with 5-65 MHz or 5-85 MHz return paths, keeping four 6.4 MHz SC-QAM signals below 42 MHz and then loading one OFDMA channel above 42 MHz is ideal. Your SC-QAM channels should be fully optimized with dynamic profile modulation up to 64-QAM. Then, by placing your OFDMA channel above 42 MHz, you’re ensuring its likely to be in a low noise environment. A bonus is that subscribers with in-home amplifiers

Cable Modems Crashing with OFDMA

Mia Colabrese2021-06-07T14:51:59-04:00June 3rd, 2021|

Why are the DOCSIS 3.1 Cable Modems Crashing with OFDMA This too shall pass. Yes, we’ve seen this before: OFDMA + DBC = BSoD Yes, you have experienced it. Either as a subscriber or technician. The cable modem is on but there is no data flowing through it. Reboot the modem and it works again. It’s the equivalent of the Microsoft Windows blue screen of death (BSoD) and it’s back with a vengeance for cable operators running DOCSIS 3.1 OFDMA with a noisy upstream. What gives? I will
