Did you say ISDN *Primary* Rate Interface (PRI), the big expensive one

the 2B+D Basic Rate Interface (BRI)? So it's basically a channelised
T1/E1 card, right? Do you know if it can do E1 or just T1? If it
can do E1, my friend Stacy Minkin in Uzbekistan was looking for a PCI
channelised E1 card and probably still is. It isn't ISDN, though,
just a channelised E1. He wants to connect an E1 line from their old
municipal telephone switch (classic traditional telephony, pre-ISDN,
pre-other modern innovations) to an Asterisk Linux-based VoIP gateway.

The P8 card is basic, not primary rate.
There are many vendors for channelised E1 PCI cards around now- try a
search on something like 'dual port E1 PCI" and you should get quite a
few.

By the way... it's been a year or four since I dabbled in this stuff,
and I never paid much attention to ISDN, but... ISDN is a whole lot of
complexity on top of the basic wires. Channelized T1/E1 is a very
simple thing, and if you have that, there should be plenty of
solutions from many places. ISDN may use that at the bottom layer,
but then you pile LAPD or whatever that pile of acronyms was on top,
and things are far more complicated.
Hopefully Mike's friend just needs channelized E1 without the baggage.

Unfortunately, it's an ISA board. Check out their Vantage series which is
all PCI. I'm not sure if they have a Vantage E1 card but probably.
You could also try Dialogic and Natural Microsystems, but Rhetorex (now
Brooktrout) was what I used and they made good products. Dialogic is the
Microsoft of the PC telephony world (lots of marketing hype but mostly
crap products) and NMS were a bunch of snakes. Hssssss.

Don't forget that Dialogic is owned by Intel.
