What does STS1 (payload) represent?

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

What is STS3c (signal) in SONET?

STS3c (signal) is a concatenated SONET transport signal combining three STS-1 channels, providing a 155.52 Mbps rate for high-bandwidth streams.

Why convert from STS1 payload to STS3c signal?

Converting helps network engineers aggregate STS1 payloads into STS3c signals for effective provisioning and bandwidth planning in SONET networks.

Does this conversion reflect actual network throughput?

No, it assumes standard SONET rates; real throughput may differ due to overhead and framing.
