For ISDN configuration, please follow the Configuring your Dial-Up Modem Connection instructions for the version of Internet Explorer that you run. After step two, you will see a menu that asks which modem you want to use. Select your ISDN modem here.

Note: For best ISDN performance, you should update your version of Internet Explorer and operating system components to the most current revision. To do this, choose "Windows Update" from the Start menu in the lower left corner of your Windows screen, or point your browser to: Windows Updates.
