11.1 Overview
This chapter provides a detailed description of ONT performance monitoring.
11.2 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
11.3 ONT performance monitoring functions
7342 ISAM FTTU provides the following functionality to simplify the usage of
performance monitoring tools:
• Monitor at the edges per subscriber and per aggregate: The system provides
counters at the edges where the subscriber originates and terminates. For
example, these counters are performed on the ONTs and edge devices such as
BRAS or Edge Router. This counting empowers the service providers to solve
their own monitoring issues.
• Perform error counting: The system provides error counters and aggregate
counters at places other than where per subscriber significance is necessitated.
These counters are used to quickly identify and obtain a high level view of the
activity at a given point in the network.
• Perform on-demand monitoring: This function allows the service provider to
issue a count request on an ad hoc basis to isolate and monitor a situation further
based on a criterion, such as per service, per VLAN, and per multicast stream.
Operators can use TL1, CLI, or an element management system (EMS) interface to:
• enable counters and set filters
• monitor performance
• view performance
