What does T1 (payload) measure in data transfer?

T1 (payload) measures the usable user-data throughput of a North American T1 digital carrier, which carries 24 channels at 64 kb/s each, totaling 1.536 megabits per second.

Why convert from T1 (payload) to terabyte per second?

Converting allows users to compare legacy telecom bandwidth with modern high-performance data transfer rates in data centers and HPC environments.

Does T1 (payload) include line framing overhead?

No, T1 (payload) excludes the 8 kb/s framing and overhead bits, focusing only on user data throughput.

What contexts use terabyte per second as a unit?

Terabyte per second is used to quantify very high-bandwidth links such as NVMe SSD arrays, HPC interconnects, and large data center backbones.

Tips & Best Practices

Understand that T1 (payload) excludes framing overhead and measures only user data throughput
Use this tool to bridge legacy telecom units to contemporary data transfer metrics accurately
Keep in mind the SI convention for terabyte differs slightly from tebibyte in some computing contexts
Consider the relative scale difference when converting from low-rate T1 units to high-rate TB/s units

Limitations

T1 (payload) represents relatively low data transfer speeds compared to terabytes per second, resulting in very small fractional outputs
Differences between SI terabyte and binary tebibyte may cause variations in precision
The unit is specific to legacy North American telecom carriers and excludes overhead bits, limiting use in modern networks
