General Malfunctions
78 ISDN-Controller B1 PCI v4.0 – 16 Troubleshooting
Applications like Connect32 are unable to connect to
analog dial-in ports.
Only connections to ISDN remote systems are possible with
your ISDN-Controller. With appropriate software such as
FRITZ!fax, for example, you can connect to Group 3 (analog)
fax machines.
DOS and Windows drivers loaded at the same time
Load either the DOS driver or the Windows driver for your
AVM ISDN-Controller, not both at once. The Windows driver
also supports CAPI-based DOS applications in DOS win-
dows.
No connection charge information is displayed
The drivers for the ISDN-Controller B1 PCI v4.0 allow CAPI-
based applications to display charge information. This in-
formation is only available if the corresponding ISDN ser-
vice has been enabled by your ISDN carrier. Depending on
the ISDN carrier, it may be necessary to enable this service
for each B channel separately (and pay an extra charge).
Using Dual-boot Systems
To use the ISDN-Controller in a dual-boot system, install the
drivers for each of the operating systems concerned in dif-
ferent folders, such as IDRIVER.WXP and IDRIVER.W95k.
