Tips & Best Practices
-
Confirm that your use involves SONET/SDH synchronous optical networking
-
Use the precise conversion factor for accurate aggregation calculations
-
Remember this tool focuses on payload unit conversions, not direct data rates
-
Consider network management overhead separately when planning capacity
Limitations
-
Conversion assumes ideal mapping without overhead or framing inefficiencies
-
Actual payload capacity can be impacted by error correction and network management
-
Not accurate for direct data rate conversions outside SONET/SDH payload aggregation use
