What is a Virtual Tributary 1 (payload)?

It is a sub-rate container within SONET/SDH frames used to carry lower-rate signals multiplexed into a higher-rate optical stream, such as mapping DS1/T1 channels.

Why convert Virtual Tributary 1 (payload) to STS1 (payload)?

To aggregate multiple low-rate channels into a higher-rate payload for transport over optical network backbones and support capacity planning.

Does this conversion include overhead or signaling bits?

No, the conversion is based on standardized payload sizes and does not factor in overhead or signaling bits.
