1.4.6 NT Server-to-Router Callback for DCC

I. Network requirements
A router and an NT server implement PPP callback via the serial interfaces across
PSTN.
As shown in the following figure, RouterA and the NT server are interconnected via the
modems across PSTN. In this case, C-DCC is adopted. RouterA is specified as the
callback client and the NT server as the callback server. Callback is implemented
according to the configuration of the dialer route command. The NT server uses the
address 100.1.1.254, and RouterA accepts the address assigned by the NT server.
