5 Troubleshooting
English
Please note that after the test program has run, CAPI is no
longer available (you may see the error message “Common
ISDN API Version 2.0 is not installed”). Reload the AVM
Mobile ISDN-Controller M2 using the appropriate program
for your operating system, i.e. ibase.bat for DOS or M2
Load in Windows 3.x.
5.2 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 allocation of system
resources (interrupt levels and I/O addresses). In DOS
and Windows 3.x, use the program msd.exe. In
Windows 95/98, conflicts are reported in the Device
Manager (Settings/Control Panel/System).
Have you made changes in your computer’s BIOS
setup?
Have you changed the configuration of your system
(boot menus, memory managers, etc.)?
You are unable to place a data or fax call.
Verify the following:
Is the Controller inserted firmly in the PCMCIA slot?
Is the correct cable connected to the GSM or ISDN
socket on the Controller card (with the triangular mark
towards the top side of the card)? Is the other end
securely connected to the GSM cellphone or to the
ISDN socket?
Use an ISDN telephone to verify that your ISDN line is
working correctly.
Are you able to make ordinary voice calls with the GSM
mobile phone?
If the telephone is a Siemens S4: does it have a valid
firmware release (26. 9. 1995 or later)?
In case of doubt, ask your dealer.
