What does Virtual Tributary 1 (payload) represent?

It is a SONET/SDH sub-rate container used to carry lower-bit-rate signals multiplexed into a higher-rate optical stream for efficient transport.

Is E.P.T.A. 1 (signal) a standard data transfer unit?

No, E.P.T.A. 1 (signal) is a vendor- or protocol-specific unit used to count signaling events rather than measuring data bits or bytes.

Why convert between Virtual Tributary 1 (payload) and E.P.T.A. 1 (signal)?

This conversion helps translate physical transport units into signaling event counts useful for diagnostics, monitoring, or vendor billing.
