Unveiling the World of DOCSIS Monitoring: Critical location detection and imminent issue resolution

In the previous part of our blog series, we discovered the importance of monitoring critical network KPIs (Key Performance Indicators) that shape the Quality of Experience (QoE) for cable broadband users. In this part, we'll delve deeper into how the AXTRACT DOCSIS & PNM (Proactive Network Maintenance) bundles harness these KPIs to pinpoint critical locations and empower service providers to proactively tackle network challenges and consequently minimize customer churn before signal impairments cause critical service degradation and customer unsatisfaction.

Leveraging KPIs for Critical Location Detection using Group Issues Locator
The AXTRACT DOCSIS and PNM bundles play a central role in gathering a diverse range of KPIs for DOCSIS devices. These KPIs are crucial in defining optimal thresholds and calculating location severity, ultimately helping identify the most critical locations within the cable network. Monitoring of all KPIs is carefully incorporated into AXTRACT's business logic in strict accordance with the specifications and guidelines set by Cable Labs.

Operating within the AXTRACT DOCSIS monitoring system, the Group Issues Locator is a component designed to boost network optimization and rapidly identify impairments that can impact the Quality of Experience (QoE) for cable broadband users. This component relies on a comprehensive set of KPIs to identify and categorize network issues which affect multiple groups of users (group network issues) by its severity. The KPIs that are considered while determining critical group network issue locations encompass various aspects of network health, including pre-equalization correlation groups, microreflections, impairments (such as power tilt, standing wave, rolloff, suck-out, adjacency, and more), and overall network health parameters.

The Group Issues Locator operates through a systematic process initiated by real-time data analysis upon data collection from the devices. This analysis carefully identifies significant network impairments and categorizes them based on their seriousness, guaranteeing that the most crucial group network issues receive top priority for resolution.

Once critical group network issues are detected and prioritized, the Group Issues Locator proceeds to create a ticket payload with all necessary data needed as an input for the field resolution. The component can trigger creation of a work order ticket, which is subsequently dispatched to field technicians for resolution. This seamless and automated process ensures that group network issues are promptly identified, prioritized, and translated into actionable work orders for field technicians. Service providers can efficiently delegate tasks, minimize service degradation and downtime, and enhance the overall QoE for their subscribers.

Streamlining Impairment Resolution: Inside the Resolution Catalogue
As a complementary module of the AXTRACT DOCSIS monitoring ecosystem, the Resolution Catalogue utilizes Axiros' domain knowledge and experience to streamline the process of addressing issues in the cable broadband network. When the system detects group network issuesand its location, the Resolution Catalogue takes action, delivering intelligent and effective field resolutions.

The power of the Resolution Catalogue lies in its ability to intelligently match detected group network issues with predefined resolution strategies. When a group network issue is identified, the catalogue analyzes the characteristics of the issue, its severity, and its potential impact on network performance. Drawing from its resolution database, the catalogue then suggests the most suitable resolution strategy, ensuring that the recommended solution aligns with industry best practices and the information collected from the field, based on previously resolved issues.

By incorporating Axiros' domain knowledge and smartly suggesting resolutions for detected group network issues, this component significantly expedites the troubleshooting and resolution process. This proactive approach enables service providers to address group network issues with precision and effectiveness, ultimately delivering a superior broadband experience to their customers.

In conclusion, the synergy of group network issues detection, location detection, and the service resolution catalogue constitutes the backbone of a robust cable network optimization strategy. With sophisticated tools like AXTRACT's DOCSIS and PNM bundles, network operators can proactively identify and address issues that impact the Quality of Experience (QoE) for cable broadband users. The precise detection of group network issues through a comprehensive set of Key Performance Indicators (KPIs) ensures that no issue goes unnoticed. The location engine takes this a step further by pinpointing critical locations within the network, enabling operators to allocate resources efficiently and initiate timely work orders for field technicians. Furthermore, the service resolution catalogue, backed by Axiros' domain knowledge, offers intelligent and context-aware suggestions for resolving group network issues. This holistic approach not only enhances network performance for groups of users but also leads to improved QoE, reduced downtime, and increased customer satisfaction. By adopting these cutting-edge solutions, cable operators can stay ahead of network challenges, deliver superior services, and ensure a seamless broadband experience for their subscribers.
