What does STS1 (signal) represent?

STS1 (signal) is the fundamental SONET electrical signal unit with a line rate of 51.84 megabits per second, corresponding to the OC-1 optical carrier and used for synchronous optical networking transport.

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

No, E.P.T.A. 2 (payload) is not generally standardized; it is specific to the E.P.T.A. 2 protocol and reflects the amount of user data in a single message as defined by that protocol.

Why convert STS1 (signal) to E.P.T.A. 2 (payload)?

Converting STS1 (signal) to E.P.T.A. 2 (payload) aligns SONET transport rates with application-level message payload sizes, aiding in throughput analysis and protocol integration.
