DOCSIS Pre-Equalization Video

Mia Colabrese2022-01-07T09:01:46-05:00February 5th, 2014|

DOCSIS Pre-Equalization Video This DOCSIS pre-equalization video will cover some important items. DOCSIS Pre-Equalization is something that every cable provider should know about. With a simple line of code on the CMTS, you can achieve an immediate and significant improvement in your upstream signal levels. Pretty important stuff, so we’ve tapped Brady Volpe, one of the foremost experts on the subject. On Tuesday, February 4th at 4:00 PM EST, Brady will be chatting live on this page with Scott Helms, ZCorum’s VP of Technology, about the benefits of pre-equalization.

PNM and HFC Readiness for DOCSIS 3.1 – CCTA 2014

Mia Colabrese2021-12-15T10:11:40-05:00February 3rd, 2014|

Daniel Howard, CTO of the Society of Cable Telecommunications Engineers (SCTE) presented at this years CCTA on "HFC Readiness for DOCSIS 3.1". Daniel had a presentation that couldn't be beet and held the attention of the audience. Key topics he covered were the rapid growth of Internet traffic, cable operator's desire to extend the life of coax cable at least another 20 years, PNM and the realization that 4096-QAM is a reality in the cable plant.

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

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

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

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
