Controller B1 v3.0 – 16 Troubleshooting

l
Is your ISDN line active? Use another terminal device,
such as an ISDN telephone, to check it.
l
Is your network terminator (NT) installed correctly?
Some NTs must be connected to an electrical outlet as
well as to the incoming ISDN line.
l
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?
l
Are all the pertinent services (for data connections)
available and enabled in your PBX?
l
Did you indicate the correct D-channel protocol for your
ISDN line in installing the ISDN-Controller software?
Problems arise during ISDN-Controller operation:
If problems occur regularly during operation, run the pro-
gram “B1 Test”, located in the “AVM” program group or in the
installation folder of the driver software. This program per-
forms functional tests of the ISDN-Controller’s components
and displays the results.
If “B1 Test” reports no malfunctions in the ISDN-Controller
hardware, attempt a test connection to the AVM Data Call
Center. Use the program “Connect2” or “Connect32”, both of
which are included among the AVM ISDN-Tools supplied with
your ISDN-Controller. The number of the AVM Data Call Cen-
ter is +49-(0)30 39 98 43 00.
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).
Load the AVM ISDN-Controller B1 v3.0 once again by running
the appropriate program for your operating system, such as
IBASE.BAT in DOS or “B1 Load” in Windows.
