IP, IPX, and AppleTalk Dial-Up Environments 5-17
Dial-In Configuration Examples
IPX Dial-in Example
The following configuration example enables a PC client running a PPP application to dial in to a
network and access IPX resources. The modem attached to the access server is a Telebit T3000
modem. For security, the access server uses TACACS+ for lines and asynchronous interfaces and
RADIUS for an ISDN interface (attached via an external ISDN terminal adaptor).
Modem and Line Configuration
The following sample configures lines 1 through 16 on a Cisco 2511 access server for modem
control. It assumes you have a Telebit T 3000 modem.

Security Configuration
This configuration uses remote security. It uses TACACS+ security for lines and asynchronous
interfaces, and RADIUS security for ISDN interfaces. This portion of the configuration only
contains security commands. Modem and protocol configuration commands are presented in the
sections “Modem and Line Configuration” and “Protocol Configuration.”
