Configuration example for NT server-to-router callback with

DCC

Network requirements

As shown in Figure 55:

• Router and NT Server are interconnected through modems across a PSTN network.

• NT Server is assigned the IP address of 100.1.1.254/24.

• Router accepts the address assigned by NT Server.

Configure PPP callback with C-DCC between Router and PC, specifying Router as the callback

client and NT Server as the callback server to make return calls according to dialer routes.
