Is there a way how to setup external USB ISDN device (such types of devices
usually people call ISDN TA)?

And how?
My model is Elcon NT1+Multi USB ISDN TA device.

I think that device is like standard modem but it works on USB (it works
with AT command).
I tried with acm and /dev/usb/ttyACM0 and ttyACM1 but don't work with

Usually that types of devices have both RS232 and USB ports, but mine have
not (my telephone provider asked manufactured to deliver devices without
RS232 ((.

So, now I have real problem to configure Linux ((.

Please help.
Thanks in advance, Mladen.

A modem was not detected among the above PCI devices.
This indicates that the modem, if present has a non-standard or ISA bridge.
Please follow the directions in ModemData.txt.2 for identifying the modem
when booting under Microsoft Windows. Also access any documentation sources
on yourchipset. Guidance can only be provided AFTER
the chipset and/or its drivers have been identified.
