ISDN-Controller B1 PCI v4.0 – 16 Troubleshooting 77

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?
 Did you specify the correct D-channel protocol for your
ISDN line when installing the ISDN-Controller soft-
ware? Lines installed in Europe after 1994 are general-
ly DSS1 lines (Euro-ISDN lines).
Problems during operation of the ISDN-Controller.
If problems with operation of the ISDN-Controller occur, es-
tablish a test connection to the AVM Data Call Center. You
may do so using the program Connect32 (Windows 7,
WindowsVista, WindowsXP), which is included in the AVM
ISDN-Tools included with delivery of your ISDN-Controller.
The ADC’s number is [phone].
In Windows2000, WindowsNT, Windows98, Windows95,
Windows 3.x and MS-DOS, you can also run the “B1 Test”
program located in the “AVM” program group and in the
folder of the driver software on the installation CD. This pro-
gram performs functional tests of the ISDN-Controller’s
components and displays the results.
After you have run the diagnostic program “B1 Test”, the
CAPI interface is no longer available (error message:
COMMON-ISDN-API Version 2.0 is not installed).
Reload the ISDN-Controller B1 PCI v4.0 using the corre-
sponding program for your operating system, e.g.
IBASE.BAT in DOS or “B1 Load” in Windows 95/3.x.
Windows 2000: Restart the computer after performing the
test program.
