What does STS1 (payload) represent in telecommunications?

STS1 (payload) is the user-data capacity within an STS-1 frame in SONET networks, with a line rate of 51.84 Mbps and a usable payload rate of 50.112 Mbps.

Why convert STS1 (payload) to T1 (signal)?

Converting from STS1 to T1 helps translate high-capacity SONET payload rates into the more granular T1 channels used widely in North American telecom, assisting in provisioning and network planning.

Are overhead and framing bits considered in the conversion?

This conversion assumes ideal payload capacity and does not include overhead or framing details, which may affect actual throughput on physical networks.
