ISDN-Controller B1 PCI v4.0 – 15 Troubleshooting

This chapter describes general malfunctions and specific er-

ror messages, and suggests remedies. The error messages

are grouped according to the operating systems in which the

ISDN-Controller B1 PCI v4.0 can be operated.

The AVM ISDN-Controller is not detected or not initialized.

Have you installed new hardware components or changed

the configuration of existing hardware?

If you combine adapters without plug-and-play support (Leg-

acy) such as the AVM ISDN-Controller B1 v3.0 in the same

system with PCI or ISA plug-and-play cards, the resources

(I/O addresses and IRQ levels) used by the hardware without

plug-and-play support should be so designated in the com-

puter's BIOS. Otherwise, system resources may be allocated

to more than one adapter, resulting in malfunctions. Please

see your computer or mainboard manual.

You are unable to establish an ISDN connection.

If the ISDN-Controller is correctly installed but you are unable

to establish a connection, check for the following conditions:

Is the ISDN-Controller firmly inserted in the PCI slot? Is

its slot plate screwed down?

Are the ISDN cable connectors firmly connected to the

ISDN-Controller and the ISDN socket?

Is your ISDN line active? Use another terminal device,

such as an ISDN telephone, to check it.

Is your network terminator (NT) installed correctly?

Some NTs must be connected to an electricity supply as

well as to the incoming ISDN line.

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?
