What is STS3c (payload)?

STS3c (payload) is a SONET level-3 payload container used in optical networks that carries high-bandwidth signals with a gross line rate of 155.52 Mbps.

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

E.P.T.A. 3 (payload) is a protocol-specific data unit representing the size of a single payload transaction in systems implementing the E.P.T.A. 3 format.

Why convert between STS3c and E.P.T.A. 3 payloads?

Converting allows translation of optical transport measurements into protocol-specific units needed for diagnostics, capacity planning, and policy enforcement.

Examples

1 STS3c (payload) equals 4.89375 E.P.T.A. 3 (payload).
2 STS3c (payload) converts to 9.7875 E.P.T.A. 3 (payload).

Common Use Cases

Backbone optical links carrying Ethernet or IP circuits between nodes using STS3c payloads.
Logging payload sizes for E.P.T.A. 3 transactions in diagnostics and auditing processes.
Capacity planning and throughput estimation for networks handling E.P.T.A. 3 formats.
Enforcing limits and quotas on APIs managing E.P.T.A. 3 payload transactions.

Tips & Best Practices

Consider SONET framing overhead when interpreting STS3c payload sizes for precise conversions.
Use this converter for approximations and initial planning rather than strict exact calculations.
Verify your system’s specific E.P.T.A. 3 implementation details, as payload sizing may vary.
Validate conversions with actual network measurements in critical applications.

Limitations

STS3c payload values exclude some overhead bytes, so the usable size is slightly lower.
E.P.T.A. 3 payload sizes depend on system implementation, possibly affecting conversion precision.
