38 Controller C4 – 8 Troubleshooting
l If your ISDN-Controller C4 is connected to a PBX exten-
sion, have you included the outside dialing prefix
(usually ‘0’) in configuring your application software?
l Are all the pertinent services for data connections
available and enabled in your PBX?
Problems arise during ISDN-Controller operation:
If problems occur regularly during operation, run the pro-
gram “C4 Test”, which is found in the “AVM” program group
(Windows NT 4.0) or in the installation folder of the driver
software. This program performs functional tests of the
ISDN-Controller C4’s components and displays the results.
If “C4 Test” reports no malfunctions in the ISDN-Controller
hardware, attempt a test connection to the AVM Data Call
Center (ISDN file transfer server). You may do so using the
program “Connect32” (Windows NT 4.0), which is among the
AVM ISDN-Tools included with your ISDN-Controller. The
number of the AVM Data Call Center is [phone].
Applications such as “Connect32” are unable to connect to
analog dial-in ports.
To connect to analog systems, you need appropriate commu-
nication software in addition to the AVM ISDN-Controller C4.
With fax software, for example, you can dial connections to
Group 3 (analog) fax machines.
No connection charge information is displayed.
The drivers for the AVM ISDN-Controller C4 allow CAPI-based
applications to display charge information. This information
is available only if the corresponding ISDN service has been
enabled on your ISDN lines by your ISDN service provider.
Contact your ISDN service provider to request charge infor-
mation on each of your ISDN lines.
Using Dual-Boot Systems
To use the AVM ISDN-Controller C4 in a dual-boot system, in-
stall the drivers for each of the relevant operating systems in
a separate directory, such as \IDRIVER.WNT.
