4.2 ONT performance monitoring
Performance monitoring is a tool that provides up-to-date information to measure 
how well the system is doing. Performance monitoring data at the ONT level include 
counters and alarms that enable service providers to do the following:
• set a baseline for performance
• get a high-level view of the activity at a given point in the network
• detect problems when they occur
• diagnose the cause of problems
• plan for development and growth
