What Is This Tool?
This converter enables you to transform data rates measured in modem (110), an early teleprinter and dial-up transmission speed, into STS12 (signal), a modern high-capacity SONET network rate. It bridges legacy low-bit-rate units with contemporary synchronous optical transport signals.
How to Use This Tool?
-
Enter the data transfer rate value in modem (110) units
-
Select modem (110) as the original unit and STS12 (signal) as the target unit

Tips & Best Practices
-
Use this converter to support legacy system emulations and historical data comparisons
-
Verify unit selections carefully to ensure accurate conversions
-
Consider differences in framing and encoding when relating modem (110) rates to STS12 signals
-
Use results for theoretical understanding due to vast scale differences between units
-
Complement conversions with additional context about network technologies in use
Limitations
-
The conversion is theoretical given the large technology gap between units
-
Modem (110) speed is extremely slow compared to STS12, making direct practical conversions rare
-
Differences in signal framing, encoding, and overhead affect rate alignment
-
May not reflect exact network performance due to unit and technology differences
Frequently Asked Questions
-
What does modem (110) stand for?
-
Modem (110) refers to an early data transfer rate of about 110 bits per second used in old dial-up and teletype communication systems.
-
What is STS12 (signal)?
-
STS12 is a synchronous transport signal used in SONET networks with a line rate of 622.08 Mbit/s, commonly employed in high-speed fiber optic backbones.
-
Why convert modem (110) to STS12?
-
Converting helps compare low-speed legacy data rates with modern high-speed optical network rates, useful in telecom infrastructure planning and legacy system emulation.
-
Is the conversion exact for real networks?
-
No, the conversion is theoretical due to differences in signaling methods and technology generations between modem (110) and STS12.
