What does 1 T1 (signal) equal in STS3 (payload)?

1 T1 (signal) corresponds to approximately 0.0102703278 STS3 (payload) in terms of payload capacity.

Can I use this tool for physical interface conversion?

No, this tool provides capacity equivalence for planning purposes but does not convert physical interface standards.

Why might actual throughput differ from the converted values?

The conversion excludes framing and overhead bytes, and line conditions can affect the effective data rates.
