Embracing Proactive Network Maintenance with AI

Mia Colabrese2024-09-09T11:20:30-04:00September 9th, 2024|

The Future of DOCSIS Networks In an industry known for its reactive problem-solving prowess, shifting to a proactive approach in proactive network maintenance (PNM) could be transformative. Instead of constant firefighting, what if we could prevent those fires from starting in the first place? Proactive network maintenance is the key to this paradigm shift, leveraging the power of AI to revolutionize how we maintain and enhance our DOCSIS networks. The limitations of reactive maintenance The cable industry has long prided itself on its ability to respond swiftly to

The Reactive Power of DOCSIS PNM Tools

Mia Colabrese2024-01-16T11:28:31-05:00December 5th, 2023|

In the demanding realm of DOCSIS networks, being proactive has become a necessity, not a luxury. To ensure efficient operation of these networks, cable operators must embrace proactive network maintenance (PNM) tools. These resources not only offer the ability to anticipate and address network issues before they significantly affect service delivery, thus creating a more robust and reliable network for users, but they can also be utilized reactively to help optimize the workforce, improve subscriber quality of experience (QoE) and are not impacted by supply chain constraints. Let’s

PMA-PNM Connection in DOCSIS 3.1

Mia Colabrese2023-11-30T08:58:56-05:00November 29th, 2023|

DOCSIS 3.1 modems have ushered in a new era of high-speed connectivity. However, ensuring their consistent performance, especially in the face of network impairments, demands a robust strategy. This is where the synergy of the profile management application (PMA) and proactive network maintenance (PNM) becomes invaluable. The twin pillars of optimal network performance 1. The PMA is designed to compensate for RF impairments in OFDM and OFDMA channels—it doesn’t fix the impairments, but goes a long way to work around them. Function: PMA is dedicated to refining the data
