What is STS3c (payload)?

STS3c (payload) is the concatenated payload container in SONET providing a single contiguous transport channel at a gross rate around 155.52 Mbps.

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

Converting to megabit/second (SI def.) allows comparison of optical transport payload rates with common digital data transfer speeds used for internet and network throughput.

Does this conversion reflect actual data transfer rates?

The conversion assumes full payload use, but actual rates may be lower due to SONET overhead and signaling variations.
