you have two options you can pass to pppd daemon: demand and idle. with the first option when pppd starts the ppp interface will be created but no real connection will be made until first datagram is sent. with the second option you can specify how many seconds the connection may be kept idle (that is, no traffic passing thru) until the device will be disconnected.
