3.      Installation:       

        The following illustration shows the mounting bracket of 
        your ISDN adapter board (16 bit):

        Use the DIP switches S1..S5 on the board to select the I/O address  
        and IRQ line of the ISDN adapter board:

         -------------------------------- ----- -----    
        | I/O address                    | S1  | S2  |   
        |--------------------------------|-----|-----|   
        |   160h ( default setting )     | off | off |   
        |   170h                         | off | on  |   
        |   260h                         | on  | off |   
        |   360h                         | on  | on  |   
         -------------------------------- ----- -----    
 
         -------------------------------- ----- ----- ----- 
        | IRQ                            | S3  | S4  | S5  |
        |--------------------------------|-----|-----|-----|
        |   2                            | off | off | off |
        |   3                            | off | off | on  |
        |   5                            | off | on  | off |
        |  10* ( default setting )       | off | on  | on  |
        |  11*                           | on  | off | off |
        |  15*                           | on  | off | on  |
         -------------------------------- ----- ----- ----- 
         * only if a 16-bit slot is used

               - - - - - - - - - - - - - - - - - - - - - - - -

        a.) Choose the COM port using the DIP switches.

            If you want an different setting, please read your manual or
            have a look on your board.

        b.) Install the MicroLink ISDN board in your PC
            considering the usual safety rules (look manual).

        c.) Load the desired driver. Consider the D channel
            protocol of your ISDN line (DSS1 or 1TR6) and the selected
            B channel protocols (with or without ISO 8208 / T.90).

        d.) To use the driver under WINDOWS '95 please add the call
            to the AUTOEXEC.BAT.

        V.120 under CAPI 1.1 and CFOS (version newer than 07/15/96):

        Enter the following AT-command:

            AT B12 S17=1 S76=1

        Now, the ISDN adapter board tries to get a V.120 connection
        erverytime you dial "ATDn" (n = number)..

        If you want to get back to X.75 mode, you have to enter:

            AT&F
