isdn4bsd (i4b) has been implemented right after the specs. It follows the
guidelines given in I.430, Q.921 and Q.931 as close as possible with
respect to the implementation of the layer itself as well as the inter-
layer communication. Each layer is implemented around a table-driven
state machine. It is much much much more modular than bisdn.

Bisdn was getting a large hack due to the monolithic design, if you changed
something here you broke something there. I simply wanted something which
is a bit longer maintainable and more easily changable and extensible.

It will have incoming telephony support, support for IP over raw HDLC and
(hopefully, it is not integrated yet) synchronous kernel PPP support.

It can be used with 2 cards as a ISDN D channel protocol analyzer and B
channel dump/display tool - in fact i'm using it to debug itself.

It currently supports just the Q.931 protocol, but it seems someone works
on one of the US protocols.

> - What cards will be/ can easily be supported?

Passive ISA non-PnP Teles, Creatix, Dr. Neuhaus Niccy (1016/1008) and
3Com/USRobotics. Some other cards of this class may be supported in the
near future. 

Due to the modularity it is very easy now to add cards with the Siemens 
ISAC/HSCX chipset.

Preliminary support for an active Diehl Card, planned support for AVM B1
and Stollmann Tina-dd active cards.

I hope to add support for some of the new passive PCI cards.

Donations of any active or passive cards and docs are welcome.

I don't think that more persons in this case lead to an earlier release
date. I tried it without success.

But i wouldn't say no to someone hiring me in my daytime job to get more
work done on it ;-)

Never heard of it. In case this is a passive card using the Siemens chipset
it will be very easy to support.

And no, snapshots of the code are not available currently. As soon as i have
anything which might be installable without me answering questions about it
the whole day long it will be announced on this list. In 1997 i thought i
could release something by the end of that year, it now seems that it will
take some months longer - there were just some things in my life other than
i4b which required my attention and i4b required much more of my attention
and my other resources than i initially thought ;-)
