What does STS12 (signal) represent?

STS-12 is a synchronous transport signal used in SONET networks with a line rate of 622.08 megabit per second, carrying multiplexed digital payloads and SONET overhead.

How does megabit/second (SI def.) differ from other bits measures?

Megabit per second (SI definition) counts one million bits per second, distinguishing it from binary units such as mebibits, which are based on powers of two.

Why convert STS12 (signal) to megabit/second?

Converting to megabit per second helps users understand and compare SONET line rates with typical broadband and network throughput metrics.
