What does STS3c (signal) represent?

STS3c (signal) is a SONET electrical transport signal combining three STS-1 channels into a single contiguous payload, carrying a gross data rate of 155.52 Mbit/s.

What is a Virtual Tributary 1 (payload)?

A Virtual Tributary 1 (payload) is a sub-rate container in SONET/SDH frames that carries lower-rate signals multiplexed into higher-rate optical transport streams.

Why convert STS3c to Virtual Tributary 1 units?

Converting allows breaking down high-bandwidth signals into standardized lower-rate tributaries, aiding multiplexing, switching, and traffic grooming in telecom networks.
