What Is This Tool?
This tool converts data transfer rates from modem (110), a legacy low-speed transmission rate, to STM-4 (signal), a high-capacity optical transmission rate used in modern telecom networks.
How to Use This Tool?
-
Enter the data transfer rate value measured in modem (110) units.
-
Select modem (110) as the source unit and STM-4 (signal) as the target unit.
-
Click the convert button to get the equivalent STM-4 (signal) rate.
Key Features
-
Converts data transfer speeds between modem (110) bits per second and STM-4 (signal).
-
Provides quick, browser-based unit conversion for telecommunications and networking.
-
Supports analysis of legacy modem rates within contemporary optical transport contexts.
Examples
-
110 bps (1 modem 110) equals about 1.7682613168724e-7 STM-4 (signal).
-
550 bps (5 modem 110) converts to approximately 8.841306584362e-7 STM-4 (signal).
Common Use Cases
-
Comparing vintage teleprinter or teletype modem speeds with modern optical network rates.
-
Emulating legacy dial-up link performance in protocol testing and vintage computing.
-
Integrating and documenting low-speed telemetry links within current SDH telecom frameworks.
Tips & Best Practices
-
Understand that modem (110) rates represent nominal bit rates from early dial-up systems.
-
Use the tool for comparison and analysis rather than exact throughput planning due to rate differences.
-
Consider the context of data link technology when interpreting conversions between these units.
Limitations
-
Conversion results are extremely small due to the vast difference in data rates between modem (110) and STM-4.
-
Does not include factors like modulation methods or encoding overhead affecting actual throughput.
-
May not be practical for direct use in current network capacity planning or design.
Frequently Asked Questions
