Using CCR 10-16G for 1gb client router

We are installing quit a bit of fiber.

Does any body have the ppoe on these routers controlled by a radius server.

IE we would like to use the router for high end clients but as the ppoe connects a client via wan1 ( example)
We would like to do the same for the ethernet ports of the routers.

Thus we can run 1G lines to clients.

Does anybody have an idea on this?
