What does 1 STS1 (payload) represent in data capacity?

It represents the user-data capacity inside a SONET STS‑1 frame, with a usable payload of 50.112 Mbps.

What is a Virtual Tributary 2 (VT2) signal used for?

VT2 carries a 2.048 Mbps payload (an E1 channel), enabling lower-rate PDH circuits to be multiplexed within SONET/SDH frames.

Why convert from STS1 (payload) to VT2 signal units?

The conversion breaks down high-capacity SONET payloads into multiple VT2 channels for efficient transport of E1/PDH circuits.

Does this conversion account for protocol overhead?

No, it assumes ideal multiplexing and does not include overhead or framing variations.
