What is a Virtual Tributary 1 (signal)?

It is a logical sub-channel in SONET/SDH that carries lower-rate digital signals with independent grooming and switching.

What does E.P.T.A. 2 (payload) measure?

It measures the amount of application or user data in a single E.P.T.A. 2 protocol message, defined by that protocol's specification.

Why might conversions between these units vary?

Because E.P.T.A. 2 payload sizes and encoding can differ, and overhead or framing variations affect actual data throughput.
