3. In the Tasks pane, click Manage network connections.

4. Right-click the dial-up connection that uses ISDN, and then click Properties.

6. In the ISDN Configure dialog box, do one or both of the following:

   • In Line type, click the line type you want to use. The line types are listed from highest to lowest quality.

   • If you want to start negotiation with the line type you selected, and then negotiate with a lower-quality line type depending on the line's condition, select the Negotiate line type check box.
