• You should be familiar with Cisco IOS software and its conventions.
Note To use the verification steps described in this chapter, you must be familiar
with Cisco IOS commands and command modes. When you use the
verification steps, you need to change to different command modes. If you are
not familiar with command modes, see the “Understanding Command Modes”
section in the “Introduction to Router Configuration” chapter.
Asynchronous Dial-Up Connection
In this configuration, a modem is attached to the router serial port. The modem
dials into the central-site router over a standard telephone line, which is an
asynchronous connection. The Cisco router is dialing into a central-site router.
These are the major tasks in configuring your router for an asynchronous dial-up
connection:
• Configuring Global Parameters
• Configuring Security
• Configuring the Fast Ethernet Interface
• Configuring the Asynchronous Interface
• Configuring When the Router Dials
• Configuring Command-Line Access to the Router
Figure 8-1 shows the configuration example used in this section.
