What does OC12 represent in telecommunications?

OC12 is a SONET optical carrier rate carrying 12 STS‑1 channels, with a nominal data rate of 622.08 megabits per second, used in high-capacity fiber-optic networks.

What is a T3 (signal) and where is it used?

T3, also known as DS3, is a North American digital transmission format carrying multiplexed voice and data at 44.736 megabits per second, commonly used for high-capacity leased lines and carrier backbone links.

Why convert from OC12 to T3 (signal)?

Conversion aids in understanding and integrating different network segments, especially when working between high-capacity SONET fiber links and legacy T-carrier infrastructure.
