5 Troubleshooting – Error Messages

Error message: The interrupt does not work.

Possible error source: The interrupt (IRQ) may be

assigned to another hardware component which was not

installed with a driver correctly in NT.

Solution: Set the AVM Controller A1 to another IRQ.

Turn off the computer, change the jumper position on the

Controller and then restart Windows. Start the A1 Setup

program and follow the instructions on the screen. See

also section 4.1.

Error message: The ISDN-Controller has not been found,

has not been activated by the system or does not work

properly.

Solution: Perform the Controller installation again. Work

through the steps in the sequence listed in the installation

routine in section 3.2. If problems persist, contact AVM

Support. See section 5.3 for contact information and

useful instructions.

5.2.4 Error Messages in Windows 3.x

Error message: “No AVM ISDN-Controller with the config-

ured I/O address found.”

Possible error source: The jumper position on the

Controller which determines the I/O address does not

correspond to the settings in the A1 Setup program, the

I/O address is used by another hardware component

(e.g. sound card), or the hardware is not installed.

Solution: Find out which I/O addresses are available in

your PC and set the jumper position on the Controller

accordingly (see Chapter 4,“Technical Specifications”).

Then enter the new I/O address in the driver software

using the A1 Setup program from the “AVM” program

group. Windows must be restarted for the changes to be

implemented.
