What does STS1 (payload) represent?

STS1 (payload) indicates the user-data capacity within an STS-1 SONET frame, commonly used for provisioning and throughput calculations in telecommunications.

Is E.P.T.A. 2 (signal) a standard data transfer unit?

No, E.P.T.A. 2 (signal) is a vendor- or project-specific label and not recognized as a standard unit in SI, IEC, or common metrology.

Why convert STS1 (payload) to E.P.T.A. 2 (signal)?

Conversion helps translate standard SONET payload capacities into proprietary signal metrics used for diagnostics, telemetry, or performance tracking within specialized equipment.
