What Is This Tool?
This converter allows you to translate data transfer values measured in T4 (signal), a high-order trunk signal in legacy North American telecom networks, into IDE (PIO mode 0), a CPU-driven data transfer mode for vintage computer storage devices.
How to Use This Tool?

Examples
-
1 T4 (signal) converts to approximately 10.3855 IDE (PIO mode 0)
-
3 T4 (signal) converts to about 31.1564 IDE (PIO mode 0)
Common Use Cases
-
Comparing legacy telecom trunk data rates with vintage computer storage transfer speeds
-
Testing and validating high-order PDH multiplexers and old telecom equipment
-
Diagnosing and recovering data on old PCs using IDE drives supporting PIO mode 0
-
Integrating or bridging networks and hardware using older T-carrier and IDE technologies
Tips & Best Practices
-
Use this conversion primarily for comparative analysis rather than direct performance prediction
-
Keep in mind the fundamental differences between network signal rates and CPU-driven storage modes
-
Refer to examples for clarity when inputting values
-
Consider the context of legacy telecom and vintage computing when applying results
Limitations
-
Converts between vastly different technologies with distinct data transfer characteristics
-
T4 represents high-speed network backbone data streams; IDE (PIO mode 0) reflects slow, CPU-powered storage transfers
-
Direct performance equivalence is limited—results are mostly theoretical or for comparative understanding
Frequently Asked Questions
-
What is T4 (signal)?
-
T4 (signal) is a high-order trunk signal from North American telecom infrastructure, carrying multiplexed data at around 274.176 megabits per second mainly for long-distance backbone networks.
-
What does IDE (PIO mode 0) mean?
-
IDE (PIO mode 0) is an old ATA/IDE data transfer timing mode that uses CPU-controlled read/write operations with low throughput, typically compatible with very old storage devices.
-
Why convert between T4 (signal) and IDE (PIO mode 0)?
-
Conversions help understand and compare data rates between legacy telecom signals and vintage computer storage speeds, useful in testing, diagnostics, and integrating older hardware.
Key Terminology
-
T4 (signal)
-
A high-order North American telecom trunk signal at approximately 274.176 Mbps, used historically for long-distance data transmission.
-
IDE (PIO mode 0)
-
An ATA/IDE data transfer mode with the slowest CPU-driven timing, used for legacy storage devices without DMA support.
-
Data Transfer Rate
-
The speed at which data is transmitted or received, measured in units like megabits per second or CPU-driven transfer modes.
