Streamlined Operations and Superior QoE: The PMA-PNM Connection in DOCSIS 3.1

By Brady Volpe – DOCSIS 3.1 modems have ushered in a new era of high-speed connectivity. However, ensuring their consistent performance brings new challenges

The Proactive and Reactive Power of DOCSIS PNM Tools

By Brady Volpe – From a reactive perspective, cable operators can use PNM tools to resolve subscriber issues more efficiently. A classic scenario involves resource utilization.

The Proactive Culture of PNM

By Jason Rupe – The proactive network maintenance (PNM) community has a culture of being meta-proactive by quickly improving itself. Take for example how the PNM working group (PNM-WG) at CableLabs and SCTE’s Network Operations Subcommittee Working Group 7 (NOS WG7).

Machine Learning and PNM

By Brady Volpe – Machine learning and PNM have promised to make the use of PNM data super easy. Anyone who has used PNM has likely experienced data overload. Looking through lots of full band capture (FBC) plots or tons of receive modulation error ratio (RxMER).

Let’s Use Our Coax Smarter

By Brady S. Volpe — In the U.S. there are over 72 million businesses and households using broadband services.[1] Since COVID-19 has led to more social distancing and also an increase in working from home, our broadband services are even more important. I’m a big fan of proactive network maintenance (PNM).

Please Stay Out of My House

By Brady S. Volpe — Staying out of subscriber’s homes while adding new service and supporting service calls is not a trivial task. This article discusses possible solutions to tackling the challenges during Covid.

How Good Is Your Gigabit Service?

By James Medlock – It seems like every day there is another press release announcing a new or expanded DOCSIS® 3.1 based gigabit service. Many operators have reported heavy interest from their subscriber base, looking for higher speed services to support the increasing number of devices and applications that they rely on each day.

DWDM is Coming to a Distributed Access Architecture Near You

By Mike Venter – The cable industry’s optical networks are undergoing rapid and radical changes to support new distributed access architectures (DAAs). A DAA basically involves replacing legacy analog infrastructure with new remote PHY devices (RPDs) or remote MAC/PHY devices (RMDs).

How Adaptive Equalization Works

By Ron Hranac — Let’s first look at the concept of equalization from the perspective of a cable distribution network. As you know, in a given length of coaxial cable higher frequencies are attenuated more than lower frequencies.

What Can DOCSIS PNM Do For Me?

By Brady S. Volpe — Proactive network maintenance (PNM) has been steadily growing in acceptance and popularity over the past several years with adoption amongst cable operators from Tier 1 such as Comcast all the way to the smallest Tier 4 operators.
