What does STS3c (signal) represent?

STS3c is a SONET signal formed by concatenating three STS-1 channels and has a gross data rate of 155.52 Mbit/s.

Why convert STS3c to terabit/second (SI def.)?

Converting to terabit/second allows integration of legacy SONET rates into modern network capacity planning using standard SI units.

How is a terabit/second defined in SI units?

A terabit per second equals 10^12 bits transmitted each second using decimal unit prefixes.

Can this conversion account for data overhead?

No, the conversion assumes steady-state rates and does not include overhead or protocol framing bits.

Is STS3c still commonly used in modern networks?

STS3c is considered a legacy format; many modern networks utilize different transport technologies.
