What does T1 (payload) represent?

T1 (payload) is the usable user-data throughput for a North American T1 digital carrier, representing 24 channels at 64 kb/s each, totaling 1.536 Mbps, excluding framing overhead.

How is a megabit per second (SI def.) defined?

A megabit per second (SI definition) is a unit of data transfer rate equal to one million bits transmitted each second, used to quantify digital communication link throughput.

Why convert from T1 (payload) to megabit per second (SI def.)?

Users convert between these units to relate legacy telecommunications rates to modern standardized data rates for accurate network planning and performance comparison.

Common Use Cases

Planning telecom systems with 24 simultaneous 64 kb/s voice channels on T1 trunks.
Specifying usable bandwidth for leased-line Internet or point-to-point backhaul connections.
Designing and comparing network interfaces and broadband internet speeds.

Tips & Best Practices

Understand that T1 (payload) excludes framing overhead and reflects usable data throughput.
Use this conversion to bridge legacy telecom data rates with current bandwidth measurements.
Verify network conditions as the conversion assumes ideal channel performance.

Limitations

T1 (payload) rate excludes the framing overhead, differing from the total T1 line rate.
Megabit per second (SI) uses decimal prefixes, which may differ from binary-based data units.
Conversion assumes perfect transmission without accounting for errors or additional overhead.
