What is E.P.T.A. 1 (signal)?

It is a vendor- or protocol-specific unit used to count signaling events or control messages, not a standard unit of bits or bytes.

What does Virtual Tributary 1 (payload) represent?

It is a sub-rate container in SONET/SDH transport frames that carries lower-rate signals multiplexed into higher-rate optical streams.

Can I use this conversion for standard data volume calculations?

No, the conversion maps event counts to payload units for accounting and network management, not for standard data volume or bit rate conversions.
