Your best bet for getting something like this is the Booktrout
Technologies RTNI-2E1 (formally produced by Rhetorex). It's got two E1
spans on the card and is very flexible so it should be able to be made to
work in Uzbekistan (it has upgradeable firmware).

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.
