l What is the version number of the driver you are using?
You can find this information in the Readme file in the
“AVM” program group.
l Is your ISDN-Controller connected directly to the ISDN
NT, or to a PBX extension line?
l What operating system is running on the computer in
which you have installed the AVM ISDN-Controller?
l Please specify the exact text of all error messages you
encountered.
l Describe the problem in as much detail as possible: in
what context does the error occur; what application
software are you using; etc.
Please answer the following questions in your support re-
quest as well, as these points can be very helpful in solving
your problem:
l Is the error reproducible?
l Does the “C4 Test” program in the “AVM” group detect
problems with your ISDN-Controller?
If so, what messages does it display?
l Are you able to dial up a data connection to the AVM
Data Call Center (ADC) with your AVM ISDN-Controller?
Attempt to make a test connection to the ADC with the
ISDN Tool Connect32, included with your ISDN-Control-
ler, or with FRITZ!data. Use the IDtrans protocol and dial
the number [phone].
If the connection to the ADC fails, what error messages
are displayed?
l Describe your PC configuration in as much detail as
possible, including the system type, sound card type,
any other components installed, and the allocated re-
sources (interrupts and I/O addresses).
