DOCSIS 3.0 Channel Bonding – Episode 3

Mia Colabrese2021-08-17T10:54:31-04:00June 30th, 2014|

DOCSIS 3.0 Channel Bonding - Your Questions Answered Brady Volpe and John Downey will discuss the many advantages and disadvantages of DOCSIS 3.0 channel bonding. When everything is operating properly, we have great advantages for modem speed and operation at the expense of allocating more spectrum for more DOCSIS 3.0 channels. When things are not going well, we may not be aware or we may not have the expertise to troubleshoot the situation or even remedy the issues properly. DOCSIS 3.0 channel bonding - Upstream and Downstream bonding have

DOCSIS Pre-Eq and PNM – Part Two

Mia Colabrese2021-08-17T11:03:31-04:00April 22nd, 2014|

The Benefits of DOCSIS Pre-Eq and PNM :: (Part 2) Presented by John Downey of Cisco and Brady Volpe of The Volpe Firm and Nimble This as a follow up to Part one (which can be viewed here) Part two we will cover how pre-equalization data can be used to identify upstream impairments through Proactive Network Maintenance (PNM) and why this is valable to a cable operator. Proactive Network Maintenance (PNM) in combination with DOCSIS pre-equalization are game changing technologies for the cable industry. PNM started as a technology research

Cisco’s New CMTS and Nodes – SCTE EXPO 2013 – Fresh Tech

Mia Colabrese2013-11-06T09:00:16-05:00November 6th, 2013|

Cisco's New CMTS and Nodes SCTE EXPO 2013 - Fresh Tech Feeling special having been invited into the "whisper suit" at CISCO's booth to get a first look at Cisco's new CMTS and Node. No one was permitted to take photo's so my description will have to be enough. Cisco has gotten completely out of their normal box for their new CMTS. It is much smaller than the traditional 10k. It's also much quieter than the 10k. It also looks cool. Those are the small things... What really

DOCSIS Pre-Equalization

Mia Colabrese2020-04-04T11:42:09-04:00October 17th, 2013|

DOCSIS Pre-Equalization This paper will first provide a brief primer on DOCSIS to establish a baseline for the document. Next the paper will examine what is DOCSIS pre-equalization. How DOCSIS pre-equalization works and how DOCSIS pre-equalization can be extended. In the greater context of the paper, the reader must consider the implications of the extensions of DOCSIS pre-equalization. In section 5, details will be provided on how DOCSIS pre-equalization can be used to identify plant impairments and locate those impairments to within a few feet. This turns every

Smart DOCSIS CMTS Upgrade

Mia Colabrese2021-12-14T15:36:26-05:00September 30th, 2013|

Making a DOCSIS CMTS Upgrade? Make sure you have done your homework. With all of the publicity focussed on DOCSIS on DOCSIS 3.1 many cable operators still have existing networks that are running DOCSIS 2.0 or even DOCSIS 1.1. Many conversations arise around what is the best path forward on making a smart DOCSIS CMTS upgrade. Should investments be made in addition DOCSIS CMTSs identical to equipment already installed? This is especially true when there is a lot of existing DOCSIS 1.1 and 2.0 equipment available at rock

What is DOCSIS PNM?

Mia Colabrese2021-08-17T16:17:19-04:00September 9th, 2013|

What is DOCSIS PNM and How Does it Work? Recently I wrote about DOCSIS PNM technology and a company working on is called Nimble This. In this article I want to highlight a mechanism behind how DOCSIS PNM works. DOCSIS Pre-Equalization DOCSIS PNM begins with a relatively well known DOCSIS feature called DOCSIS pre-equalization. I've previously covered adaptive pre-equalization, but here is a refresher. Starting with DOCSIS 1.1, pre-equaliztion was added to DOCSIS cable modems. It was later improved in the DOCSIS 2.0 standard adding more equalizer taps

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

Capacity Planning | Build It & They Will Fill It

Mia Colabrese2012-10-08T10:01:54-04:00October 8th, 2012|

Capacity Planning - Helps Make Future Capital Expenditure Decisions Capacity Planning in the good old days, was an issue that impacted neighborhoods with web hogs in the them. Peak usage hours were dreaded, teenagers downloading music were seen as a scourge, and web surfers were just plan old annoying. What did these people think the internet was for? How things have changed. Today people not only download music and surf the web but also watch movie content, make video conference calls, teach classes, and do just about anything else they can think of. What
