13. The system should measure or detect different events and/or failures which are on the PON network. Please indicate the wavelength handled by the system.
14. The Tenderer shall provide information about fault resolution (accuracy, resolution, measurement time, PON section failures which could be detected).
15. The following transmitter and receiver parameters must be monitored and collected in the system. The precondition for this scenario is: ONTs are ranged at the OLT.

19. The system should provide the statistics and analysis, including but not limited to the following function:
The prediction alarms statistics report
Traffic/bandwidth utilization ratio statistics report
Alarm report
All reports should support to be exported into XLS file.
20. The Tenderer shall describe and report figures on the solution’s efficiencies on the analyzing tasks, monitoring tasks, optimization tasks and maintenance tasks.
21. Where diagnostic tools are made available for the network element, it must be possible to control them via the management interface.
22. Accessing all test and measurement functions of the management system (NMS) using the external interface of the NMS shall be possible, i.e. all GUI functions must also be available at the interface.
23. The maximum capacity of testing ports that the system supports should be 96, or more.
24. The system performance of the management system (NMS) must not be impeded when executing the test and diagnostic functions (delay of commands being executed via the GUI and processing in the system including external interfaces, etc.)
25. The system shall compare the captured data and usage patterns of previous periods to detect faults and incorrect configurations.
26. The system shall provide root cause analysis of any performance degradation as inferred by an event correlation process
