This chapter provides a product overview and describes how to power on the access server to configure it using the prompt-driven setup script.
The following sections are included:
If you prefer to configure the access server manually, proceed to the next chapter "Cisco IOS Software Survival Skills" to familiarize yourself with the command line interface and then proceed to the following chapter, "Configuring the Access Server Manually" for step-by-step instructions.
The Cisco AS5200 universal access server is a versatile data communications platform that provides the functions of an access server, a router, and digital modems in a single modular chassis. The Cisco AS5200 is intended for Internet service providers (ISPs), telecommunications carriers, and other providers that offer managed Internet connections, and also small- to medium-size sites that provide both digital and analog access to users on an enterprise network.
The Cisco AS5200 receives and routes both analog and digital calls on the same chassis simultaneously. By doing so, it provides you with a clear, simple, and easy migration path from today's predominantly analog dial-in services to tomorrow's digital dial-in services. The access server enables dial-in clients to make remote asynchronous and ISDN connections to the access server.
To configure remote services, you must configure three interrelated interfaces on the access server. The loopback interface makes the network appear as if the dial-in users exist on one Ethernet segment. The loopback interface has the following four types of neighboring interfaces used for dial-in operations: ISDN interface, dialer interface, group asynchronous interface, and asynchronous interface. Figure 1-1 shows an internal view of the components used to process incoming ISDN and analog calls on an access server.
All dial-in users exist on one dial-in subnet. Remote asynchronous users dial in through the group asynchronous interface to the access server. Remote ISDN users dial in through the ISDN dialer interface to the access server. Figure 1-2 shows an external view of how remote users dial in to the access server.
Before you turn on the access server and begin to use the setup script, make sure you have already connected the cables to the access server and configured your PC terminal emulation program for 9600 baud, 8 data bits, no parity, and 2 stop bits. All configuration will be performed from your PC terminal emulation program window.

To use the setup script take the following steps:
Step 1 Power ON the access server (see Figure 1-3). The power switch is on the rear panel of the access server, at the upper right corner near the power cord.
Messages will begin to appear in your terminal emulation program window.
 | Caution Do not press any keys on the keyboard until the messages stop. Any keys pressed during this time will be interpreted as the first command typed when the messages stop, which may cause you to power cycle the access server and start over. It will take a few minutes for the messages to stop. |
The messages look similar to the following:

--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Step 2 When the following message appears, press Return to accept the default entry (yes) in square brackets:
If you answer no, go to Chapter 3, "Configuring the Access Server Manually" to configure the access server, or refer to the Quick Reference Card included with your access server.
Step 3 When the following message appears, press Return to see the current interface summary:
Step 4 Enter a host name for the universal access server:
5200
Step 5 Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when viewing the configuration:
lab
Step 6 Enter an enable password. This password is not encrypted (less secure) and can be seen when viewing the configuration:
guessme
Step 7 Enter the virtual terminal password, which is used for remote console access:
guessagain
Step 8 Respond to the following prompts as appropriate for your network:
yes
yes
15
yes
Step 9 Configure the asynchronous serial lines for the integrated modems or terminal adapters on the modules installed in the universal access server:
Configure for Dynamic IP addresses? [no]:
Configure for TCP header compression? [yes]:
Configure for routing updates on async links? [no]:
Enter the starting address of IP local pool? [X.X.X.X]: 172.20.30.40

Step 16 When the messages stop displaying on your screen, press Return to get the following prompt:
The access server now has a basic configuration for ISDN or channelized T1 or E1 (depending on your responses to the prompts). The access server should be able to accept incoming calls. However, this is not a complete access server configuration. For more advanced configuration topics, proceed to:
Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than your printed documentation.
To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription.
You can access Cisco documentation on the World Wide Web from Cisco Connection Online (CCO) at:
