What does T1 (payload) represent in data transfer?

T1 (payload) represents the usable user-data throughput of a North American T1 digital carrier, specifically 24 channels multiplied by 64 kb/s, totaling 1.536 Mbps excluding overhead.

How is a kilobyte per second (SI) defined compared to kibibyte per second?

A kilobyte per second (SI) equals 1000 bytes per second, using decimal multiples, which differs from a kibibyte per second that uses binary multiples of 1024 bytes.

Why convert from T1 (payload) to kilobyte/second (SI)?

Converting helps relate legacy telecom channel throughput to standard modern byte-based data transfer units used in computing and networking for easier analysis and reporting.

Tips & Best Practices

Understand that T1 (payload) excludes framing overhead while gross rate is slightly higher
Use the SI kilobyte/second for clear communication of decimal byte rates
Be aware this conversion assumes ideal transmission without additional protocol loss
Refer to conversion examples for accurate calculations
Apply conversion when integrating legacy telecom units into modern digital systems

Limitations

T1 (payload) rate does not include framing overhead, so total throughput is higher
Kilobyte/second (SI) is decimal-based and differs from binary units like kibibyte
Conversion assumes perfect conditions without signal degradation or protocol overhead

Key Terminology

T1 (payload): The usable user-data throughput of a North American T1 line, consisting of 24 voice channels at 64 kb/s, equaling 1.536 Mbps excluding framing overhead.
Kilobyte per second (SI def.): A unit of data transfer equal to 1000 bytes transmitted per second, using decimal prefixes for data measurement.
Framing overhead: Additional bits used in T1 lines for synchronization and control, excluded from the payload data throughput calculation.
