What is proactive network.jpg

What is proactive network maintenance and why is it essential to keep your network running smoothly?

PNM is a revolutionary philosophy. Unlike predictive, or preventive maintenance, proactive maintenance depends on a constant and rigorous inspection of the network to detect the causes of a failure—and remediation—before that failure occurs. PNM was pioneered at CableLabs in 2008. This breakthrough innovation analyzes information available in each cable modem to identify impairments in the coax portion of the cable network, making every cable modem in the network a troubleshooting device and a preventive diagnostic tool.

Preventative measures typically cost less than dealing with problems after they happen. An effective PNM program not only helps to reduce troubleshooting costs, but it also standardizes the data collection process, automates remote problem solving and provides an unprecedented amount of actionable information about the state of the network.

Together, CableLabs and SCTE are shaping the future of connectivity and creating a seamless ecosystem of innovation—our work on PNM is just the latest example. We’ve designed this exclusive course to prepare broadband professionals to better understand the elements and implementations of the multiple tools and techniques in our PNM tool kit.

How does PNM help your team find problems before they happen?

Proactive Network Maintenance can help you and your team:

  • Track transient issues related to the time of day, temperature, and other environmental variables, which can play a huge role in the performance of the cable system.
  • Provide unprecedented amounts of information about the state of the network.
  • Empower technicians to quickly and efficiently because solve problems by pinpointing where the problems are.
  • Enable customer service agents to create actionable service requests before the customer is even aware there is a problem!
