What is DOCSIS PNM?

A Comprehensive Guide | Enhancing Network Performance with Proactive Network Maintenance

Unlock the Full Potential of Your Network with DOCSIS PNM

DOCSIS Proactive Network Maintenance (PNM)

DOCSIS Proactive Network Maintenance (PNM) is a cable modem management technique that leverages IoT devices, such as cable modems, set-top boxes, and WiFi routers, to proactively monitor and manage cable networks. By collecting data from these devices, operators can detect network issues before they affect customers. PNM also helps improve network performance by identifying and addressing potential issues before they cause service disruptions. As IoT use grows, PNM's role in cable networks will become increasingly vital.

DOCSIS PNM, built on the foundation of DOCSIS pre-equalization, is a well-known feature that uses equalizer taps in cable modems to delay RF frequencies, enhancing network reliability.

Benefits

  • PNM is a proactive approach to cable operator plant maintenance

  • PNM uses cable modems and CMTS as test probes

  • PNM locates up- and downstrream impairments

  • In an ideal scenario PNM identifies impairments before they impact the customer

How Does PNM Work?

PNM works by frequently and continuously collecting data from CMTS and modems via SNMP. It involves regular monitoring of modems in the target area, analysis of distortion signatures, evaluation and classification of issues, and calculations of distances to reflection points. Finally, it plots modems on a map, providing visual representations of known issues.


The Advantage of DOCSIS
PNM

DOCSIS Proactive Network Maintenance (PNM) is a technology that enables Internet service providers (ISPs) to manage the growing number of IoT devices on their networks. By providing visibility into network devices and their activity, DOCSIS PNM helps ISPs identify and resolve issues before they cause disruptions for customers. For example, if an IoT device is consuming excessive bandwidth or generating too much traffic, DOCSIS PNM allows the ISP to detect the problem and take corrective action.

Additionally, DOCSIS PNM assists ISPs in managing firmware upgrades and security patches for IoT devices, ensuring that these devices remain up-to-date and secure. As the number of IoT devices continues to increase, DOCSIS PNM will become an increasingly vital tool for ISPs.


What Problem Does PNM
Solve?

Preventative actions are typically less expensive than dealing with issues once they arise. Every year, troubleshooting residential Wi-Fi problems consumes a significant amount of resources. An effective Proactive Network Maintenance program not only lowers troubleshooting costs but also standardizes data collection procedures, automates remote problem solving, and provides an enormous amount of actionable network information. But most significantly, it helps to build public confidence in cable service providers' dependability - without which no other metric is as important.
