16 Troubleshooting
This chapter describes general malfunctions and specific er-
ror messages, and suggests remedies. The error messages
are grouped according to the operating platforms in which
the AVM ISDN-Controller B1 v3.0 can be operated.
16.1 General Malfunctions
The AVM ISDN-Controller is not detected or not initialized.
l Have you installed other new hardware components or
changed the configuration of existing hardware?
If so, check whether conflicts have arisen in the assign-
ment of system resources (I/O addresses and IRQ lev-
els). Use the Device Manager in Windows 2000/NT/Me/
98/95, accessible from “Settings / Control Panel / Sys-
tem”. In Windows 3.x and MS-DOS, use the MSD.EXE
program included in the package.
l If you are using a computer with a PCI/ISA bus, make
sure that the interrupt selected on the AVM ISDN-Con-
troller is also available on the relevant bus (computer
setup or ICU utility).
l Have any changes been made to the computer’s BIOS
setup?
l Has the configuration of your computer been changed
(for instance, boot menus, memory manager, etc.)?
You are unable to establish an ISDN connection.
If the ISDN-Controller is correctly installed but you are unable
to establish a connection, check for the following conditions:
l Is the ISDN-Controller firmly inserted in the computer
slot? Is its slot plate screwed down?
l Is the ISDN cable firmly inserted in the AVM ISDN-Con-
troller and connected to your ISDN socket?
