Overview
Now that you have learned how to identify your communication needs and how to select the equipment, you will learn how to configure an access server for modem connectivity so that telecommuters can access the central site by using asynchronous connection. To do this, you will learn how to perform a reverse Telnet session to the modem, how to configure it for basic asynchronous operations, and how to use the modem autoconfiguration.

Dialup Terminology
Following are the definitions of two terms (taken from the Cisco Web site) that you will frequently encounter in this chapter:

Analog--An electrical circuit that is represented by means of continuous, variable physical quantities (such as voltages and frequencies), as opposed to discrete representations (such as the 0/1, off/on representation of digital circuits). Signal transmission over wires or through the air in which information is conveyed through variation of some combination of signal amplitude, frequency, and phase.

Asynchronous--Term describing digital signals that are transmitted without precise clocking.
