What does OC12 represent in data transfer?

OC12 is a SONET optical carrier rate carrying 12 STS‑1 channels at a combined rate of 622.08 megabits per second.

What is the definition of T1 (payload)?

T1 (payload) refers to the usable data throughput of a North American T1 line, which is 1.536 Mbps without overhead.

Why convert OC12 to T1 (payload)?

This helps quantify how many legacy T1 channels fit within an OC12 fiber link for network planning and resource allocation.
