What does modem (2400) represent?

Modem (2400) indicates a data transfer rate of 2400 bits per second, typical of early dial-up modem standards, and serves as a descriptive speed classification.

What is STM-1 (signal)?

STM-1 (signal) is the base transmission unit of the Synchronous Digital Hierarchy (SDH), carrying a framed synchronous signal at a gross rate of 155.52 Mbit/s.

Why convert from modem (2400) to STM-1?

Converting helps relate low-speed legacy modem rates to the high-speed backbone network standards used in modern telecommunications planning and integration.

Common Use Cases

Relating low-speed modem data rates to high-capacity backbone SDH network rates.
Analyzing compatibility between legacy modem links and modern telecom infrastructure.
Network planning involving aggregation of legacy and contemporary communication channels.
Simulation and emulation of historic or heterogeneous telecom environments.

Tips & Best Practices

Use the conversion to aid in understanding bandwidth differences in telecom upgrades.
Keep in mind that modem (2400) is a descriptive classification, not a strict SI unit.
Verify conversions with examples before applying in complex network scenarios.
Understand that practical speeds may vary due to overhead and line conditions.

Limitations

Conversion is approximate since modem (2400) is not an SI unit but a descriptive speed class.
STM-1 operates at much higher speeds, so minor rounding errors can occur with very low modem values.
Assumes ideal bit rates, not accounting for protocol overhead or real-world conditions.
