CED – Proactive Network Maintenance

Mia Colabrese2014-01-30T10:36:45-05:00January 30th, 2014|

Proactive Network Maintenance ZCorum debuts DOCSIS upstream tester ZCorum has introduced a new tool that analyzes DOCSIS pre-equalization data, which cable operators can use to identify upstream impairments. The company’s Pre-Equalization Analyzer uses technology from Nimble This to analyze the pre-equalization data from cable modems. Nimble This is a collaboration of software developers with The Volpe Firm, headed by Brady Volpe. The new ZCorum tester can not only identify upstream impairments, but also determine the location of the impairment and the severity of the impairment. This allows operators

DOCSIS 3.1: Modulation Options and Impacts – Part Two

Mia Colabrese2023-02-17T13:02:40-05:00January 22nd, 2014|

What’s Next for DOCSIS 3.1 Modulation Options and Impacts DOCSIS 3.1 modulation - Many wonder how today’s networks will support high order modulations such as 4096-QAM. There are two technologies in the DOCSIS 3.1 standard that will enable this without requiring changes to existing outside plant. The first is Orthogonal Frequency Division Multiplexing (OFDM). This is a complex word for taking many small QAM channels, like 25 kHz instead of 6 MHz, and placing them very close together. OFDM also has dynamic properties. If you have a block

PNM - Proactive Network Maintenance CableLabs Booth - SCTE EXPO 2013 - Fresh Tech The PNM demonstration in the CableLabs booth was very popular at this years SCTE EXPO as was Armstrong and Comcast. Both very impressive. Comcast's demonstration of their PNM Scout Flux solution by the SCTE Pavilion was most impressive. It won the BTR 4.5 diamond award in 2012, but it is not for sale. Now Comcast has been working on their solution for over five (5) years with a team of smart people working on

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 Modulation Options and Impacts – Part One

Mia Colabrese2022-01-07T11:29:37-05:00October 25th, 2013|

What’s Next for DOCSIS Modulation Options and Impacts This paper is the second in a series titled “What’s Next for DOCSIS:” (Young, 2012), and outlines the anticipated DOCSIS near, medium, and long term next generation (NG) network specifications; identifies and presents high spectral efficiency (SE) modulation options capable of enabling DOCSIS 3.1/NG network specification compliance; identifies the likely modulation technique winner(s) and why; and finally presents NG network operational, test, and troubleshooting challenges facing network installers and repair technicians.

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

Solving Problems DOCSIS PNM

Mia Colabrese2021-08-18T09:55:46-04:00October 13th, 2013|

Solving Problems with DOCSIS PNM Solving problems with DOCSIS PNM in the outside plant is one of the most exciting aspects of PNM. If this if the first time your reading on my PNM articles, check out my first and second articles on the PNM application. This is some really cool tech to come to the cable industry. The premise is that we are turning cable modems into troubleshooting devices. So far I've really just introduced the concept, so in this article I will give a real world example that
