Nimble This supported by the Volpe Firm team up with ZCorum to offer a new way for cable operators to find and address network and in-home issues before they impact subscribers. San Juan, PR January 27, 2014 — At the CCTA show today, ZCorum, a leading provider of managed broadband services and diagnostics software, and Nimble This, the leading developer of commercial PNM solutions for the cable industry, announced the launch of a new product that helps cable providers leverage the benefits of DOCSIS pre-equalization, while making use of that data

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

Impact of Impulse Noise on Adaptive Pre-Equalization Part II

Mia Colabrese2021-08-18T09:36:31-04:00March 1st, 2012|

In part I of this article I discussed adaptive pre-equalization in DOCSIS cable modems and how it can compensate for many upstream impairments such as frequency response, group delay and micro-reflections. I also left off with a cliff-hanger, which is also the title of the article; impulse noise has an impact on adaptive pre-equalization, but how and what is it? I'll cover both what impulse noise is and why and how it impacts adaptive pre-equalization.

Impact of Impulse Noise on Adaptive Pre-Equalization

Mia Colabrese2021-11-24T09:26:04-05:00February 29th, 2012|

For those of you who have attended my seminars you are familiar with adaptive pre-equalization in cable modems (if not I'll explain it in detail momentarily). Also, if you have done any amount of RF plant troubleshooting you are certainly familiar with Impulse noise (again, I'll cover this too). But if you are like me, I never knew that the two topics were co-related.
