10 Troubleshooting
This chapter describes general malfunctions, specific error
messages and offers tips on correcting such errors. The error
messages are sorted by the various operating systems under
which the AVM ISDN-Controller A1 PCMCIA can be run.
10.1 General Malfunctions
The AVM ISDN-Controller A1 PCMCIA is not detected or not
initialized.
l Have you installed new hardware or changed the confi-
guration of the existing hardware?
If so, check for any conflicts in the assignment of PC re-
sources (interrupt, I/O address). To do this, you can e.g.
use the MSD.EXE program. In Windows 95/98, used the
Device Manager (“Start / Settings / Control Panel / Sys-
tem”) and in Windows NT, use the “Windows NT diagno-
sis” program from the “Administration” program group.
l Have you made any changes to the computer’s BIOS
setup?
l Have you changed the configuration of your computer
(e.g. boot menus, memory manager, etc.)?
You cannot establish an ISDN connection.
If you cannot establish a connection, despite correct installa-
tion of the AVM ISDN-Controller A1 PCMCIA, check the follow-
ing points:
l Is the ISDN-Controller inserted firmly in the computer’s
PCMCIA slot?
l Is the ISDN connecting cable plugged firmly into the
AVM ISDN-Controller? Is the cable connected with an
ISDN socket?
l Check whether your ISDN socket is functioning proper-
ly, e.g. by connecting an ISDN telephone.
