I put a 8 port BRI card in my Definity, created the data stations, then plugged them into my BRI ports on my Cisco 3600. It works like a charm. I couldnt find any support on this when I was trying to do it, but finally got it to work on my own. Good luck!
Here is how my 3600 BRI is configured:
!

no cdp enable
ppp authentication ms-chap pap
Here is my data extension on the Definity:
