Built a framework to predict problematic cable system interfaces for a European cable operator

Challenge

• Subscribers were facing video quality issues like video freeze, tiling, macro-blocking
• The problems were known after customer complains
• MTTR peaked at 14 - 16 hours
• Field engineers had to hop to multiple locations to find the root cause

Solution

• Built an automated solution using our predictive analytics framework to predict the problematic interface using network and box data
• Integrated the solution to a dashboard which provided a unified view, along with real-time alerts
• Centralized monitoring was set up to predict faulty CMTS interfaces
• Plugged-in live at the customer location, with an accuracy of up to 82% across frequencies

Results & Benefits

• Reduced MTTR from hours to minutes
• Reduced the service call volumes
• Radically improved customer experience
• Huge ROI for the operator due to the reduced operating costs
