What does Virtual Tributary 2 (payload) represent?

It represents a SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel, enabling the transport of lower-rate TDM signals over optical networks.

Is E.P.T.A. 2 (payload) a standardized unit?

No, E.P.T.A. 2 (payload) is specific to the E.P.T.A. 2 protocol and its exact size and semantics depend on that protocol's own specification rather than external standards.

Why convert from Virtual Tributary 2 to E.P.T.A. 2 payloads?

To facilitate integration and monitoring of legacy SONET/SDH signals alongside newer protocol payloads for throughput analysis and provisioning in mixed network environments.
