Tips & Best Practices

Consider the significant speed difference when converting between modem (300) and T3 (payload).
Use conversions for high-level comparisons rather than precise throughput estimations due to differing overheads.
Apply this tool for educational, documentation, or planning purposes involving legacy and modern telecom systems.

Limitations

The conversion spans vastly different data rates, so numerical precision may have limited practical relevance.
Modem (300) rates are nominal and historical; actual throughput can vary based on line conditions and protocol overhead.
This tool does not account for real-world variations or performance factors in data transfer speeds.
