You can connect to the internet via CAPI and even have it dynamically
add/drop channels as calls are setup/pulled down by other applications. As
for how to do it I have no idea because I have no need for that type of
setup.

It's not that hard to install and configure the card with capi. It's more
that you may run into difficulties and trying to find the info required to
fix them is a task.

I'm pretty sure everything you need can be achieved through purely CAPI
interfaces. There's a lot of info out there if you search for fritz capi ppp
on google.

On the positive side you won't have to go through a lot of frustration
getting the fritz working.

In summary using an analogue adaptor on ISDN rather defeats the purpose of
ISDN."

You are absolutely spot on. I am hesitated by the sheer amount of
configuration with the ISDN driver.

The actual implementation is actually even a bit of complicated. The
ISDN is used primarily for internet connection and voip from an
Australian provider. In that case I need to use whatever driver to
intiate dail up to the internet. Will it be isdn4l in this case. Now if
and when internet is down for whatever reason, asterisk can still
perhaps use the capi driver to connect calls.

I don't have much experience in isdn at all. I am not sure where such
setup can be done simitaneously. It would be nice if someone can point
me to the right direction.

The Telstra connection already come with Nt1 +11 modem and I have
already got pretty good doc to set it up with redhat 9.0. So I don't
have to worry about isdn stuff. I wish to go the correct route which is
using Fritz card to do this but I am afraid it is not possible.
