You would need the 4-port BRI card from Junghanns www.junghanns.net/asterisk
<http://www.junghanns.net/asterisk>  which runs in both NT and TE modes.
 
Alternatively, for a small system (one BRI in, one BRI out), you can use a
couple of Billion or Asus ISDN cards (around EUR30 each).  I am running Asterisk
at home in exactly the configuration you describe.  You will need to download
the bri-stuff drivers from Junghanns web site and compile using the scripts
included.
 
For the card in NT mode you will need to make a crossover cable with
terminations.  You can do this with a patch cord, an RJ45 socket and two 100 ohm
resistors for termination.  Magic!

Hi List,

card to the telco?

Patrick,

it's not possible to connect the existing pbx with an AVM Fritz card.
The card has to support the NT mode. You can do this with all cards
based on the HFC-S PCI A chipset (which have a streetprice of around
EUR 25 to EUR 30) or with our quadBRI and octoBRI card.

best regards

Klaus
