How many PM bins can be stored, for each data collection point, on PSS systems?

Comprehensive and Detailed Explanation From Nokia Optical Networking Fundamentals:

Performance Monitoring (PM) is critical for maintaining the health of a Nokia 1830 PSS network. The system collects data such as FEC corrected bits, optical power levels, and ODU-layer errors. According to Nokia's standard node management architecture, each data collection point (such as an optical port or an ODU termination point) stores a specific number of historical "bins" locally on the card or the shelf controller.

The standard storage capacity for these PM statistics is33 x 15-minute bins(covering the last 8 hours and 15 minutes of granular data) and8 x 1-day bins(covering the last week of daily totals). Additionally, there is1 raw binwhich contains the "current" accumulating data that has not yet been shifted into a completed 15-minute or 24-hour historical bin. This allows network operators usingWS-NOC(WaveSuite Network Operations Center) to retrieve recent historical performance data directly from the NE (Network Element) even if the management system was temporarily disconnected. If longer-term history is required, the management system must be configured to poll and archive these bins into its own database before they are overwritten on the hardware.
