What is a Virtual Tributary 1 (signal)?

It is a logical sub-channel in SONET/SDH used to encapsulate lower-rate signals within a higher-rate synchronous frame, allowing independent grooming and switching.

What does STS3c (payload) represent?

STS3c (payload) is a concatenated SONET payload container providing a single contiguous transport channel with a line rate of about 155 Mbps, used to carry high-bandwidth client signals.

Why would I convert Virtual Tributary 1 signals to STS3c payload?

This conversion helps aggregate multiple lower-rate digital signals into a higher-rate contiguous payload for efficient optical transport and network management.
