What is STS3 (payload)?

STS3 (payload) refers to the user-data portion of a SONET STS-3 frame, representing bytes available for client traffic after excluding overhead and framing.

What does a Virtual Tributary 2 (payload) represent?

A Virtual Tributary 2 (payload) is a SONET/SDH container designed to carry a 2.048 Mb/s PDH/E1 channel, enabling transport of lower-rate TDM signals within a higher-rate optical frame.

Does this conversion account for SONET overhead bytes?

No, the conversion focuses on payload capacities and assumes standard definitions, excluding overhead and framing differences beyond standard SONET specifications.

Can this conversion be used for non-SONET/SDH systems?

No, it is specifically intended for SONET/SDH payload contexts and may not apply in other network or transmission environments.
