Configuring multilink between 2 routers using CSNT

I've got 2 routers which are interconnected using frame-relay for primary link and I'm using ISDN as backup with CSNT. Everything works fine but i'm not to sure as how to get ppp multilink going so I can get both B channels up using CSNT. I have added ppp multilink in CSNT, but where do I need to apply it? Do I just apply it for the user under CSNT (do I need any custom attributes) or do I have to apply the ppp multilink on the NAS as well? I've looked for examples but didn't find any.

I'm also trying to get CSNT to pass the dialer map command to the routers instead of having the dialer map sitting on the routers, anyone knows if that is doable?

I want to had that the less I've got on the main router the better it is because as this is only in testing mode right now, the plan is to get the main router with a couple of PRI cards to be able to backup over 70 sites.
