• Microsoft Windows for Workgroups version 3.11

This article provides instructions to install ISDN on your Windows for Workgroups version 3.11 computer. These instructions are divided into the following sections and should be performed in the order given:

• Before You Install ISDN
• To Install ISDN
• To Add an Entry in Remote Access Service (RAS) to Call an ISDN Server
• To Receive Incoming Calls on the ISDN Line

Before You Install ISDN

1. Because ISDN service is not available in all areas, check with your local telephone company to see if ISDN service is available in your area before you order an ISDN board.

2. If ISDN service is available in your area, you can order an ISDN card from Digi International at (612) 943-9020.

3. When you order ISDN lines from your local ISDN service provider, make note of the following information they give you because you will need to enter it in Windows for Workgroups when you set up ISDN:

       - Service Profile ID (SPID)
       - Switch type
       - Line type
   

4. Obtain the ISDN Windows for Workgroups version 3.11 software from Microsoft.

To Install ISDN

1. In the Program Manager window, double-click the Network Setup icon, or use the arrow keys to select the Network Setup icon, and then press ENTER.

2. Choose the Drivers button.

3. Choose the Add Adapter button.

4. In the Network Adapters box, select DigiBoard PCIMAC - ISA ISDN Adapter, and then choose the OK button.

5. Follow the on-screen instructions, and then when you are prompted with the DigiBoard PCIMAC - ISA ISDN Adapter Card Setup dialog box:

   a. For IRQ Level, choose Disabled. b. For I/O Base Address, choose an address that is not used by any

         other device yet; if in doubt, leave at the default of 0x320.
   

   c. For Memory Base Address, choose an address that is not used by any

         other device yet; if in doubt, leave at the default of 0xD0000.
   

   d. For Switch Type, select the switch type you got from your ISDN

         service provider.

         see the RAS Help file.)
   

   c. For Number Of Logical Terminals, leave at the default of 1. (This

         information is provided by the ISDN service provider. For more
         information, see the RAS Help file.)
   

   d. Enter your Service Profile ID (SPID) number in the format provided

         by your ISDN service provider.
   

   e. Enter your ISDN phone number, which is probably identical to your

         seven-digit SPID.
   

8. Choose the OK buttons and Close buttons as prompted until you are prompted to choose Restart Computer or Continue; at this point, choose the Restart Computer button if you don't have any unsaved open files in other applications.
