Tips & Best Practices

Always verify units before converting to ensure accurate data transfer representation
Consider network overhead and framing impacts on usable payload capacity
Use conversions for planning interoperability between SONET and SDH systems
Cross-check with network specifications when integrating different protocols
Remember that conversions represent gross line rates, not net usable bandwidth

Limitations

Conversion reflects gross line rates without accounting for additional overhead
STS3c payload capacity is slightly less than its gross line rate due to framing bytes
Network configurations or encapsulation may require further adjustments beyond this conversion
This tool does not calculate usable bandwidth affected by frame structures
