4 Troubleshooting

The hardware and software of the AVM ISDN-Con-
troller T1/T1-B are set at the factory to permit
trouble-free installation and operation under most con-
ditions.

If problems should arise, first check whether the AVM
ISDN-Controller T1/T1-B is correctly installed in
your system.

Before you contact your dealer or AVM’s support
technicians, please follow these troubleshooting pro-
cedures:

4.1 The “Power” LED is not lit.

Cause:

The  AVM ISDN-Controller T1/T1-B is not being
supplied with electrical power.

Possible remedies:

- Make sure the power adapter is firmly plugged into

the power outlet.

- Check the power adapter’s connection to the AVM

ISDN-Controller T1/T1-B. The three-pin connec-
tor must be secured by tightening the muff.

- Check the voltage of your power outlet. It should be

230 V ±10% AC at 50 to 60 Hz.

4.2 When the ibase driver is loaded, the

message “No processors found” ap-
pears.

Cause:

The AVM ISDN-Controller T1 does not respond to
your PC.
