I've recently helped someone set up ISDN with one of the newer PCI
cards, but I really think i4b is still too harder than getting
something like a courier I-modem. Those little isdn modems are not
that much more expensive than the cards, plug into a com port and
function exactly like a normal modem. AT commands and all.
You can set one up, with normal user ppp and everything works a dream,
no nasty kernel configs required either, and IMHO, i4b seems a little
too untested. Hopefully that won't upset anyone, but I just didn't
like i4b myself, which could have been from bad experiences when it
If you do use an i-modem instead of an ISDN card the idiots guide is
just the same as if it were a normal modem and normal ppp, and there's
a lot more knowledge available to help you if things go wrong with
Good luck, although, your mileage may vary of course,
