The SDCC channels provide an in-band management path within a fiber rings, of which there are two interfacesone for each side of the fiber. It's a point to point topology. Multiple SDCCs become multiple paths or even rings.
Using CTM or CTC, you can creat a circuit, so that a SONET frame (packet) know its way to the other end. The paths can be chosen from SDCCs you have in your SONET network. There is no need of routing protocols because a circuit is predefined. That's why we call it a circuit. You can think of it as a telephone network where a path has to be established before you can begin a conversation.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
