What does Modem (2400) represent?

Modem (2400) denotes a modem data rate of 2400 bits per second, typical of early dial-up modem standards like ITU‑T V.22bis.

What is STS3c (payload)?

STS3c (payload) is a SONET payload container with a gross line rate of 155.52 Mbps used to transport high-bandwidth client signals over optical networks.

Why convert between these two units?

Users convert between Modem (2400) and STS3c (payload) to relate legacy low-speed data rates to modern high-capacity optical transport channels for analysis and network planning.

Tips & Best Practices

Remember that Modem (2400) is a descriptive speed, not an SI unit.
Use this tool to understand scale differences in telecommunications technology.
Consider overhead and framing effects in STS3c when analyzing payload capacities.
Use conversions mainly for comparison and planning rather than precise real-world throughput.

Limitations

Modem (2400) defines a general speed classification, not an exact standard unit.
STS3c payload is slightly less than its nominal value due to framing overhead.
Large difference in scale limits direct practical comparisons between units.
Conversions may not reflect actual usable bandwidth in all scenarios.
