DDR: Dial-on-demand Routing
Dial-on-demand Routing (DDR) is a technique that enables router automatically initiate and close a circuit-switched session as transmitting stations demand. The router spoofs keep alive so that end stations treat the session as active. DDR permits routing over ISDN or telephone lines using an external ISDN terminal adapter or modem.
