well, just off the top of my head, if you are using bridge mode (your router like a modem) and you are trying to get the connection to dial at a specified time then:
Download route sentry, select the connection either as international or local, click the check box that says automatically reconnect.
Then use windows scheduler to start route sentry at that time, when route sentry opens and sees that the connection is not active it will dial it for u.
Just my 2cents as a quick workaround off the top of my head.
