What Is This Tool?
This converter allows you to switch between STS3c (signal), a high-bandwidth telecom transport signal, and IDE (UDMA mode 2), an older PC data transfer mode. It helps users compare different data transfer technologies for applications in networking and legacy hardware analysis.
How to Use This Tool?
-
Enter the value in STS3c (signal) representing your data rate.
-
Select the target unit as IDE (UDMA mode 2).
-
The tool calculates the equivalent IDE (UDMA mode 2) value based on the conversion rate.
-
Use the result to assess compatibility or compare transfer speeds.
Key Features
-
Converts data transfer units between STS3c (signal) and IDE (UDMA mode 2).
-
Uses a defined conversion rate reflecting theoretical throughput equivalence.
-
Supports comparisons for telecom and legacy PC hardware transfer rates.
Examples
-
1 STS3c (signal) equals approximately 0.5891 IDE (UDMA mode 2).
-
2 STS3c (signal) converts to about 1.1782 IDE (UDMA mode 2).
Common Use Cases
-
Provisioning high-bandwidth leased-line circuits in telecom networks using OC-3c/STS-3c.
-
Configuring or checking legacy PC BIOS settings for ATA/33 transfer modes.
-
Comparing and benchmarking telecom backbone signals against legacy PC drive transfer speeds.
-
Troubleshooting data transfer or compatibility issues in PATA systems.
Tips & Best Practices
-
Understand the differing contexts: telecom signals versus PC disk transfer rates.
-
Use conversions for theoretical capacity comparisons, not direct performance metrics.
-
Apply the tool to support compatibility assessment and performance benchmarking.
-
Consider environmental or protocol overhead factors when interpreting results.
Limitations
-
Conversion equates theoretical transfer capacities of very different technologies.
-
Cannot account for practical performance differences caused by protocols or overhead.
-
Not suitable for precise measurement of actual data throughput in real environments.
Frequently Asked Questions
-
What does STS3c (signal) represent?

STS3c (Synchronous Transport Signal level 3, concatenated) is a telecom electrical transport signal with a gross data rate of 155.52 Mbit/s, combining three STS-1 channels for high-bandwidth streams.
-
What is IDE (UDMA mode 2)?
-
IDE (UDMA mode 2), also known as ATA/33, is a PATA interface transfer mode offering a theoretical maximum rate of about 33.3 megabytes per second for host-drive data transfers.
-
Why convert between STS3c (signal) and IDE (UDMA mode 2)?
-
Users convert between these units to compare data transfer capabilities across telecom network signals and legacy PC hardware for purposes like benchmarking, compatibility checking, and system integration.
