M = Memory chips (8 x 44C256 80ns)
Below these there are eight empty sockets that look as if they could
take another set of 44C256...
SM = 9-pin Sub-D socket male
SF = 9-pin Sub-D socket female
The male plugs into a 9-SubD to Western style ISDN cable, the female
accepts a male equipped (with only four pins) that ends in a (German style?)
2x4 ISDN "telephone-style" plug similar to the German 2x3 TAE plug (top

Drivers for Win.311, Win9x, NT and Linux are available at: http://www.avm.de
Presently, I''ve got the MCA card to work under Win311
and Win95 (should work under 98, too, if you get that running at all).
Since it is an ***active*** ISDN card powered by its own processor, the
workload on the machine is tiny -- no noticeable slowing down on the 9595-xNx.
As for NT, I've managed to get the card recognized and installed (both
the service and the driver), however, every time I start Fritz! - that
should plug into the capi port -- it tells me there is no CAPI 2 present.
If I hit the "Load B1" button, it tells me that the IRQ (5) and the
I/O port (150h) are already occupied (which is no surprise since the card
is loaded at startup....). I'm still working on that one.
The main advantage of the AVM card over, say, the IBM
WaveRunner, is that AVM have managed to implement a perfectly working CAPI
2.0 interface on every kind of card they made. And there is the really
outstanding Fritz! software (downloadable at the above site, too) that
plugs into AVM's CAPI port -- excellent for faxing/voice mail, but foremost
for data transfer (on tow lines simultaneously at 2x64 kbit, giving huuuge
transfer rates with V42 soft compression, especially if there is another
FRITZ! at the other end). The necessary software (WIN.311, 9x and NT) is
downloadable from the above site.
I've not yet managed to get the card running under Linux,
however, it is one of the projects running, and I think we shoudl come
up with a solution in due course.
