What does STS1 (payload) represent in telecommunications?

STS1 (payload) is the user-data capacity carried inside a SONET STS‑1 frame, with a usable payload rate of 50.112 Mbps.

Why convert STS1 (payload) to E.P.T.A. 1 (payload)?

Converting helps translate SONET payload capacities into the protocol-specific units of E.P.T.A. 1 for accurate throughput calculation, buffer sizing, and billing.

Can this converter handle overhead and error correction differences?

No, the conversion assumes standard payload definitions without overhead, and variations in error correction or framing may affect accuracy.
