What does Virtual Tributary 1 (payload) represent?

It is a sub-rate container in SONET/SDH used to carry lower-rate signals multiplexed into a higher-rate optical transport frame.

Is T1Z (payload) a standardized unit?

No, T1Z (payload) is an informal term used to denote the payload portion of a T1/DS1 circuit excluding overhead.

Why convert between these two units?

Converting helps align SONET/SDH sub-rate payloads with T1 user-data payloads for accurate throughput estimation and network management.
