What Is This Tool?
This converter helps translate data transfer rates between the T4 (signal), a high-order trunk signal from the legacy PDH T-carrier system, and the STS3 (signal), a SONET digital transmission signal widely used in modern synchronous optical networks.
How to Use This Tool?
-
Enter the numeric value of T4 (signal) you wish to convert.
-
Select T4 (signal) as the input unit and STS3 (signal) as the output unit.
-
Click the convert button to see the equivalent STS3 (signal) value.
-
Use the results to compare legacy and SONET signal rates effectively.
Key Features
-
Converts T4 (signal) data rates to the equivalent STS3 (signal) values.
-
Supports legacy and modern telecom signal comparisons.
-
Browser-based and easy to use unit converter tool.
-
Facilitates planning for network upgrades and interoperability.
-
Provides quick reference for historical and current telecom standards.
Examples
-
1 T4 (signal) converts to approximately 1.76 STS3 (signal).
-
5 T4 (signal) equals about 8.815 STS3 (signal).
Common Use Cases
-
Assessing equivalence between legacy PDH T-carrier signals and modern SONET signals.
-
Planning upgrades or interoperability between older telecom infrastructure and SONET networks.
-
Testing and validation of telecommunications equipment involving high-order trunk signals.
-
Supporting maintenance of legacy T-carrier networks in specialized or private settings.
Tips & Best Practices
-
Use this converter as a reference tool during telecom network planning or upgrades.
-
Understand that real network conditions may introduce slight variations from theoretical conversions.
-
Keep in mind the legacy nature of T4 signals when applying conversions to modern infrastructures.
-
Apply results to support equipment testing, validation, and maintaining legacy systems.
Limitations
-
The conversion is based on ideal signal rates without overhead or protocol-specific differences.
-
T4 (signal) is largely legacy and may not be supported in current network equipment.
-
Practical implementations of STS3 (signal) can vary due to hardware differences.
-
Conversions are mainly theoretical or useful for maintenance rather than live network usage.

Key Terminology
-
T4 (signal)
-
A high-order trunk signal in the North American T-carrier hierarchy, carrying multiplexed channels at around 274.176 megabits per second, primarily used in legacy long-distance carrier networks.
-
STS3 (signal)
-
A Synchronous Transport Signal level 3 in SONET networks with a line rate of 155.52 megabits per second, used to carry multiple lower-rate channels across synchronous optical or electrical transport systems.
-
SONET
-
Synchronous Optical Networking, a standard for synchronous data transfer over optical fiber.
