Site to Site using a Concentrator 3005 and a 1702 router

[andeeeeuk]

We want to utilise our current concentrator 3005 which is being used for some clients at the moment.
Want to add a cisco 1702 router to create a site to site connection for an office of users.

as I understand I will have to create a new ipsec group on the 3005 with a preshared secret.

What will i need to do at the router end to connect upto the concentrator from the beginning.

Thanks in advance
