Lesson 2: Configuring Dial-Up Connections

A dial-up connection connects you to a private network or the Internet by using a

device that transfers data over a public telephone network. This device can be a

modem that uses a standard phone line, an ISDN card with a high-speed ISDN line, or

a DSL modem that requires a dial-up connection. In this lesson, you learn to configure

a modem in Windows XP Professional and create a dial-up connection. You also learn

to configure Windows XP Professional to allow an incoming connection.

After this lesson, you will be able to■ Configure a modem in Windows XP Professional.■ Create a dial-up connection.■ Configure Windows XP Professional to allow incoming connections.Estimated lesson time: 30 minutes

Play–compliant. For the most part, users can create a dial-up connection that uses a

modem without ever having to configure the modem itself. There are times, however,
