I think this would involve making sure that you plug the TX (SC or ST) plug into the OC3 interface's RX jack (SC or ST) opening, and vice-versa. I can't afford ATM for my lab, but I remember thinking it was neat that you could do some basic ATM stuff without the switch. If you are asking for some guidance at a more advanced level than this basic cabling level, then forgive my post.
