What Is This Tool?
This unit converter enables users to translate data transfer speeds measured in T4 (signal), a legacy telecommunications rate, into gigabit per second (Gb/s), a modern unit used to specify network throughput. It helps bridge legacy PDH network measurements with current digital communication standards.
How to Use This Tool?
-
Enter the value in T4 (signal) units you want to convert.
-
Select 'T4 (signal)' as the source unit and 'gigabit/second [Gb/s]' as the target unit.
-
Click the convert button to get the equivalent speed in gigabits per second.
-
Review the result to compare legacy and modern data rates.

-
4 T4 (signal) converts to about 1.0214 Gb/s.
Common Use Cases
-
Comparing legacy PDH network speeds with modern gigabit-capable links.
-
Supporting testing and validation of legacy telecom equipment.
-
Planning network upgrades from T-carrier infrastructure.
-
Analyzing historical telecom data rate benchmarks.
-
Integrating legacy network measurements in modern engineering projects.
Tips & Best Practices
-
Ensure you understand the legacy context of T4 (signal) when interpreting conversion results.
-
Use this conversion for raw data rates, but consider additional protocol overhead in real scenarios.
-
Incorporate conversion results when planning transitions between PDH and newer packet networks.
-
Leverage example conversions to verify calculations and interpretations.
Limitations
-
T4 (signal) units represent legacy telecommunications technology and may not match modern protocol efficiencies.
-
Conversion does not account for protocol overhead such as encoding, framing, or error correction.
-
Direct equivalence in throughput may differ in real network environments.
-
This converter assumes raw data rates without adjustments for real-world transmission factors.
Frequently Asked Questions
-
What is a T4 (signal) in data transfer terms?
-
T4 (signal) is a high-order trunk signal in the North American T-carrier hierarchy, carrying multiplexed lower-order channels at about 274.176 megabits per second, mainly used in legacy long-distance backbone networks.
-
How is gigabit per second (Gb/s) defined?
-
A gigabit per second (Gb/s) is a unit of data transfer rate equal to one billion bits transmitted each second, commonly used to specify bandwidth in digital communications.
-
Why convert from T4 (signal) to Gb/s?
-
Converting T4 (signal) rates to Gb/s helps compare legacy network speeds with modern interfaces, assists in upgrades, and supports validation of legacy telecommunications equipment.
Key Terminology
-
T4 (signal)
-
A legacy high-order trunk signal in the North American T-carrier system corresponding to the DS4 rate, used for multiplexed data at about 274.176 Mbps.
-
Gigabit/second (Gb/s)
-
A unit measuring data transfer rate equal to 10^9 bits per second, widely used to specify bandwidth in networking.
-
PDH (Plesiochronous Digital Hierarchy)
-
A telecommunications technology hierarchy for multiplexing digital signals, within which T4 is classified.
