Troubleshooting – General Malfunctions

5 Possible Errors and Remedies

This chapter describes general malfunctions and specific

error messages and suggests how these may be resolved.

Error messages are sorted by operating platform:

Windows 98, Windows 95, Windows NT, Windows 3.x

and MS-DOS.

5.1 General Malfunctions

The AVM ISDN-Controller is not detected or not initialized.

• Have you installed other new hardware components

or changed the configuration of existing hardware?

If so, check for conflicts in the interrupt and I/O

address assignments using the program MSD.EXE,

which is included with MS-DOS and Microsoft Windows

3.x. In Windows 95/98, look for resource conflicts in

the Device Manager (“Start / Settings / Control Panel/

System“). In Windows NT, run the program “Windows

NT Diagnostics” in the “Administrative Tools” folder.

• If your computer is a PCI/ISA bus system, check your

BIOS setup or ICU utility to make sure that the

interrupt you assigned to the AVM ISDN-Controller

A1 is actually allocated to the corresponding bus.

• Have you made changes in your computer’s BIOS

setup?

• Have you made other configuration changes (boot

menus, memory managers, etc.)?

You are unable to establish an ISDN connection.

If the AVM ISDN-Controller is correctly installed, but you

are unable to establish a connection, check the following:

• Is the ISDN-Controller firmly inserted in the bus slot?

Is its slot plate screwed down?
