What does STS3c (signal) represent in telecommunications?

STS3c (signal) is a SONET electrical transport signal representing a contiguous payload formed by concatenating three STS-1 channels, matching the throughput of an OC-3c optical channel with a data rate of 155.52 Mbit/s.

What is the data rate of OC12 in SONET?

OC12 carries 12 STS-1 channels at a nominal data rate of 622.08 megabits per second, corresponding to STM-4 in the SDH hierarchy.

Why convert from STS3c (signal) to OC12?

Converting STS3c to OC12 helps aggregate multiple STS3c signals into higher-capacity OC12 links, useful for efficient backbone or regional fiber transport in network planning.
