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

Windows automatically detects and installs most modern modems that are Plug and
Play–compliant. For the most part, users can create a dial-up connection that uses a

when you might need to configure or troubleshoot a modem. You will do so by using
the Modems tab of the Phone And Modem Options dialog box, shown in Figure 15-8.
