Tips & Best Practices
-
Understand that this tool converts standardized line rates without addressing overhead or framing details
-
Consider differences in SDH and SONET framing when interpreting throughput values
-
Verify equipment compatibility beyond rate conversions when planning network designs
-
Use example conversions to cross-check your results for accuracy
-
Stay aware of physical layer and vendor-specific factors affecting real-world performance
Limitations

-
Does not account for different framing structures of SDH versus SONET protocols
-
Physical transmission characteristics and hardware compatibility are outside this tool's scope
Frequently Asked Questions
-
What does STM-16 (signal) represent in telecommunications?
-
STM-16 (signal) is an SDH line rate with a gross bit rate of 2,488.32 Mbit/s used to carry multiplexed channels over optical or electrical links in carrier networks.
