Setting up 2 data ports on 820s

I'm having a little trouble figuring out service points on a link I'm trying to set up. I've used an 820s before but I usually just set it up as a pipe with 1 data port. The link I'm trying to set up now requires data to go through eth1 and eth2 to seperate switches. I've tried reading through the manual but I don't know enough to understand what it's trying to tell me. How do I need to set up the service points to make this happen?
