Smart DOCSIS CMTS Upgrade

2021-12-14T15:36:26-05:00September 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

DOCSIS 3.1: Begin Preparing Now

2013-09-12T14:45:51-04:00September 12th, 2013|

DOCSIS 3.1: Begin Preparing Now Posted on September 11, 2013 by Carl Weinschenk-BTR Experts believe that DOCSIS 3.1 is few years off. The specification has not yet been finalized. After that, test and early customer premise equipment (CPE) and corresponding CMTS and CCAP line cards will be sprinkled through systems. The bottom line is that it will be a long time until DOCSIS 3.1 is an element of everyday cable operations. So preparations should start now. The industry has been down this road before. What seems like a long road, with

What is DOCSIS PNM?

2021-08-17T16:17:19-04:00September 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

Troubleshooting Cable Networks

2020-04-02T09:57:28-04:00August 22nd, 2013|

CED Presents an Educational Webcast Troubleshooting Cable Networks - Understanding Ingress Impairments Brady Volpe will be a panelist on: "The two-way nature of cable networks is being increasingly exploited for innovative new features and services, including interactive TV applications, video conferencing, data back up, and wireless backhaul (all in addition to high speed data, VoIP, and Internet TV). Growing reliance on the return path highlights the very common problem of upstream cable ingress interferences. MSO's are planning the deployment of DOCSIS 3.1 technology to offer greater downstream/ upstream

DOCSIS PNM – Something Really Interesting!

2021-08-18T09:15:32-04:00August 21st, 2013|

DOCSIS PNM - Get Excited! Awhile back I wrote an article about DOCSIS Proactive Network Maintenance (PNM).  Not only did I find this technology fascinating I decided to really get involved with PNM.  I will also be speaking at SCTE EXPO on the topic of PNM this year.  Topic: DOCSIS Pre-Equalization: Vastly Powerful, Often Undervalued For those of you who have not heard of PNM, here are the highlights.  DOCSIS Proactive Network Maintenance (PNM) developed by InGeNeOs™ under Cablelabs®.   It is one of the coolest technologies I've been involved

A Briefer History of CableTV

2021-11-29T14:49:22-05:00August 6th, 2013|

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

2013-07-22T09:00:55-04:00July 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
