ISDN-Controller C2 – 10 Troubleshooting 53
If your ISDN-Controller is connected to a point-to-point
line, have you included the outside dialing prefix (usu-
ally “0”) in the numbers dialed?
Are all the pertinent services (for data connections)
available and enabled at your PBX?
Problems arise during operation of your ISDN-Controller C2:
If problems occur regularly during operation of the ISDN-
Controller C2, open the “Device Manager” to verify if the AVM
ISDN-Controller C2 is listed with an error message.
If the “Device Manager” 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 us-
ing the program “Connect32” (Windows NT 4.0), which is
among the AVM ISDN-Tools included with your ISDN-Control-
ler.
No connection to analog remote sites.
To connect to analog systems, you need appropriate commu-
nication software in addition to the AVM ISDN-Controller C2.
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 C2 allow CAPI-based
applications to display charge information. This information
is only available if the corresponding ISDN service has been
enabled by your ISDN service provider. Contact your ISDN
service provider to request charge information on each of
your S

lines individually.
