What does STS3c (signal) represent in a network?

STS3c (signal) is a SONET electrical transport signal composed of three concatenated STS-1 channels, providing a gross rate of 155.52 Mbit/s suited for carrying high-bandwidth streams as a single payload.

How is STS12 (signal) used in telecommunications?

STS12 (signal) carries multiplexed digital payloads and overhead at 622.08 Mbit/s, commonly used for carrier backbones, metro fiber links, and protected SONET ring architectures.

What is the conversion rate between STS3c (signal) and STS12 (signal)?

One STS3c (signal) equals 0.25 STS12 (signal), enabling aggregation of multiple STS3c signals into a single STS12 circuit.
