A Briefer History of CableTV For those in the know... A briefer history of CableTV provides an abridged version of how we got to where we are now and CableTVs impact on modern-day test equipment. Looking at the history of CableTV, its beginnings were very humble with many taking credit for its first invention. Let us not delve into those disputes, but look towards where CableTV really started to emerge in the mainstream. It was not until 1947, post WWII when TV began to start getting momentum with

DOCSIS Channel Emulator – Impairments Made Easy

Mia Colabrese2013-07-22T09:00:55-04:00July 22nd, 2013|

DOCSIS Channel Emulator - Impairments Made Easy by Averna While at ANGACOM this year I came across Averna's DOCSIS Channel Emulator (DCE). It's an interesting product that can be put to good use in an MSO lab, vendor lab or anyone needing to create real-world impairments that impact DOCSIS. Intrigued by the product, I followed up with Averna and got a hands-on demonstration at Averna's Atlanta office. Averna's DOCSIS Channel Emulator - What's Good... So first, if you are doing DOCSIS testing, it is likely that you have

DOCSIS & Testing Best Practices in an All Digital Network ANGACOM - 2013 Missed ANGACOM 2013? Don't worry, you can still see the presentation on DOCSIS & Testing Best Practices in an All Digital Network along with the speaker notes for each slide. This was only a 15 minute presentation, so time was limited on the depth of material that could be covered in the time given. Slide 2 – Overview What do I mean by all digital networks and why is the cable industry moving in this

DOCSIS Reed-Solomon Codewords

Mia Colabrese2013-03-10T20:01:38-04:00March 10th, 2013|

How many bytes can a Reed-Solomon codeword bite? In my previous article on DOCSIS Codeword Errors, reader "Sandy" asked how many Reed-Solomon codewords would be required to transport a 1518 byte length of data? This is a very good question and one that I had never considered until I first faced when designing DOCSIS data-layer models in MATLAB. In the example I used in my previous article I chose a word that was 16 bytes long. I did this because it made it easy to draw an 8x8

EPON | A Brief Primer

Mia Colabrese2012-12-03T09:00:25-05:00December 3rd, 2012|

EPON Ethernet Passive Optical Network (EPON) is an actual Ethernet network over optical cable following the IEEE 802.3av standard for 1 Gbps (supporting up to 10 Gbps). There are two (2) functional components of an EPON network, an Optical Line Terminator (OLT) and an Optical Network Unit (ONU). The OLT is analogous to a CMTS in a DOCSIS network while the ONU is similar to the cable modem. Data is transmitted to by the OLT to ONUs in the downstream by a broadcast method. Encryption is used, so

With a lot of adult content and other nefarious sites all over cyber space, it is paramount to protect your family from as appropriate. This can be done by filtering content coming into your computer. There are fundamentally two ways to successfully block adult and other malicious contents from gaining entry into your computer and your home. The first is by installing software designed to block such contents from your PC. The second way can be done at the network level. This later method does not involve the
