Install an ISDN adapter

  • Article

Applies To: Windows Server 2008

You can use this procedure to install an Integrated Services Digital Network (ISDN) adapter in your computer. When the vendor supplies specific instructions for the make and model adapter you have, follow those instructions.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

To install an ISDN adapter

  1. Connect the ISDN adapter, and then start your computer.

  2. You can use Device Manager to configure your system so that your ISDN adapter can determine what type of telephone switch it is connected to. The switch type simply refers to the brand of equipment and software revision level that the telephone company uses to provide you with ISDN service.

Additional considerations

  • If you install more than one ISDN adapter, you must restart your computer after you have installed the ISDN drivers. Otherwise, all available ISDN ports might not show up when you configure your network connection for ISDN.

  • When viewing your adapter in Device Manager, if your ISDN adapter is internal to your computer, it appears in Network adapters. If the ISDN adapter is external to your computer, it appears in Modems.
