  • CPAT Flex Ingress Detection solution

Fresh Tech | Leakage Detection with Brains!

2011-11-22T11:11:29-05:00November 22nd, 2011|

I admit that while I help my clients better understand the sources and negative impacts of RF ingress on DOCSIS in a cable plant, I have never found leakage/ingress detection itself particularly high-tech. That was until Daniel Babeux of VGI Solutions gave me a demo of their CPAT Flex Platform. The live demo was straightforward which made it so convincing and intriguing. It consisted of a truck-mount magnetic antenna that connected into a little green box (the brains behind the operation), and a piece of coax cable seemingly chewed upon by a squirrel. The latter connected back into the CATV plant. The awesome part of the demonstration was seeing the location of the antenna appear on Google maps at the Georgia Convention Center in Atlanta, GA. Next when the damaged coax was replaced, the leakage point on the map disappeared along with magnitude of the leakage entering the plant.

  • Televe's CATV Spectrum Analyzer

Fresh Tech | Awesome Spectrum Analyzer at a Cool Price!

2011-11-21T15:54:40-05:00November 21st, 2011|

What first caught my eye by Televes H45 Spectrum Analyzer was the HDMI port feeding a flatscreen television. How cool is that? I also noticed the small unit was displaying a QAM "haystack" along with its power, MER, BER, and the demodulated picture just beside the measurements. The picture was on a high resolution display, not the low quality displays I've seen in the past, so tiling or macro-blocking would be apparent to the user. See the picture below:

BTR | Rollouts Continue as DOCSIS 3.0 Matures

2022-02-15T16:04:02-05:00September 28th, 2011|

The following article just released by Broadband Technology Report was written by Carl Weinschenk.  A number of us from the industry contributed to Carl's piece, but it is a nice high-level summary article on the status of DOCSIS 3.0.  Below you will find a snippet of the article with a link to the BTR website for the complete read.  Enjoy. Rollouts Continue as DOCSIS 3.0 Matures There are just two areas of concern as the rollout of DOCSIS 3.0 continues: the upstream and the downstream. Observers seem satisfied

Cable Modems init(r1) init(r2) Why are they stuck?

2021-08-20T09:21:27-04:00September 21st, 2011|

Cable Modems init(r1) init(r2),  DOCSIS Cable Modems going offline? DOCSIS Cable Modems init(r1) init(r2) are stuck or offline! Many of us have been there before - one or more DOCSIS cable modems init(r1) init(r2) stuck in one of numerous "init()" conditions - how do we interpret these messages and what do we do? A recent reader wrote in and had just this problem. DOCSIS cable modems going offline and getting stuck in "R1" or "R2"  condition, or Cable Modems init(r1) init(r2), because these are the status conditions displayed on the DOCSIS CMTS
