What is STS3c (payload)?

STS3c (payload) is a concatenated SONET payload container providing a single contiguous transport channel with a gross rate of 155.52 Mbps, used mainly in optical networks to carry high-bandwidth client signals.

What does E.P.T.A. 3 (signal) represent?

E.P.T.A. 3 (signal) is a proprietary or application-specific data transfer unit whose precise meaning and scaling vary based on equipment or protocol definitions; it is not a standardized unit.

How accurate is the conversion between STS3c (payload) and E.P.T.A. 3 (signal)?

Accuracy depends on the specific source definitions for E.P.T.A. 3 (signal) since it is proprietary, and STS3c excludes SONET overhead, affecting exact throughput calculations.
