What does STS3c (signal) represent in SONET networks?

STS3c (signal) is a SONET electrical transport signal formed by concatenating three STS-1 channels, providing a contiguous payload with a gross data rate of 155.52 Mbit/s.

What is a Virtual Tributary 1 (signal)?

Virtual Tributary 1 (signal) is a lower-rate logical sub-channel in SONET/SDH that carries individual sub-rate signals with its own overhead, allowing independent grooming and switching.
