What is STM-1 (signal)?

STM-1 (signal) is a basic transmission unit in Synchronous Digital Hierarchy carrying a synchronous framed signal at 155.52 Mbit/s, used widely in telecom backbone networks.

What does E.P.T.A. 1 (signal) represent?

E.P.T.A. 1 (signal) is a vendor- or protocol-specific unit counting signaling events or control messages within a data-transfer system, rather than a fixed amount of data.

Why convert STM-1 (signal) to E.P.T.A. 1 (signal)?

Conversion is useful to translate a standard data rate measure into a vendor-specific count of signaling events, aiding in logging, diagnostics, or billing purposes.
