This process can easily take 10 minutes. You need to find a router that has software options to pretend the link is up all the time, and only actually dial it when needed. I.e. it has routing software that absorbs routing info and sends your routes (at the provider's end) and uses an incremental-update protocol between the routers at the time the link is up. The link is not brought up for changes in the routing info, but this is sent at the beginning of a connection brought up for other reasons. Several manufacturers are releasing such things now. The tricky part is to setup everything in such a way that it does not keep the connection all the time because of some silly packet that they (or you) forgot to filter or handle in a special way.
