I was able to translate via Google.  Looks pretty neat.  425EUR per unit if they are still in production.

Sounds like a tnc4e http://www.hbtron.de/afu/tnc4edesc.html
unfortunatly that side is in german so you might need bable fish to make
sence of it.
In short it is a tnc with 3 interchangeble modems (300 baud - 1.5 mbaud)
a serial and ethernet connector and updateable firmware.
It accepts ax25 over tcp/ip or can act as ip over ax25 bridge/router.
