What does T3 (payload) represent?

T3 (payload) refers to the portion of a T3/DS3 digital telecommunications circuit's line rate available for user data after subtracting framing, signaling, and protocol overhead.

What is a terabit per second (SI definition)?

A terabit per second (SI definition) is a unit of data transfer rate equal to 1 trillion bits transmitted each second, using the decimal-based prefix tera (10^12).

Why convert from T3 (payload) to terabit/second (SI def.)?
