1Configure the PC:

a Configure the modem connected to the PC to be in “autoanswer mode”. b Select Start > Programs > Accessories > Communications > Dialup network. c Click Set up new connection in the Dialup network window.

d Select the Server type page in the established new connection, and perform the following operations:

■Select the option [PPP]

■Set the [Logon network] option as unchecked

■Set the [Start software compression] as unchecked

eSelect TCP/IP setting in the Server type page, and perform the following operations:

■Check the option [Server allocated with IP address]

■Set the [Use IP head pointer compression] option as unchecked

■Set the [Use default gateway of the remote network] option as unchecked

NT Server-to-Router	A router and an NT server implement PPP callback via the serial interfaces across
Callback for DCC	PSTN.
	As shown in Figure 238, RouterA and the NT server are interconnected via the
	modems across PSTN. In this case, circular 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.
