What Is This Tool?
This tool converts data transfer values from STS12 (signal), a high-speed synchronous optical network signal, to modem (14.4k), a legacy dial-up modem speed, helping users compare and plan network capacity between modern and older technologies.
How to Use This Tool?
-
Enter the value in STS12 (signal) units you want to convert
-
Select STS12 (signal) as the starting unit and modem (14.4k) as the target unit
-
Click the convert button to get the equivalent value in modem (14.4k)
-
Review the results to understand capacity differences between the two units
Key Features

-
Based on raw data rate equivalences without protocol overhead
-
Supports quick and easy conversion suitable for telecommunications and network planning
-
Browser-based and user-friendly interface
Examples
-
2 STS12 (signal) equals 86,400 modem (14.4k)
-
0.5 STS12 (signal) equals 21,600 modem (14.4k)
Common Use Cases
-
Planning network upgrades comparing SONET infrastructure with legacy modems
-
Assessing compatibility between high-speed backbone networks and older dial-up connections
-
Telecommunications backbone and metro fiber link capacity analysis
-
Understanding data transfer capabilities in environments with mixed technology speeds
Tips & Best Practices
-
Use this tool to compare raw data rates when integrating new and legacy systems
-
Consider the synchronous nature of STS12 and asynchronous performance of modems when interpreting results
-
Be aware that actual throughput may vary due to network protocol overhead and line conditions
-
Validate conversions in the context of specific network environments and equipment capabilities
Limitations
-
Conversion assumes equivalence in raw data rates without reflecting overhead or throughput differences
-
Modem speeds are theoretical maximums and can be impacted by telephone line quality and noise
-
STS12 signals are synchronous and reliable, while 14.4k modems operate asynchronously with variable speeds
Frequently Asked Questions
