Yes, I asked Eicon. The cards don't have internal termination. The ports are layed out for TE mode, so depending on your ISDN bus topology, you need a termination. And you are right, when in NT-mode both sides needs termination.... just normal ISDN bus topology. Since I have only one termination in the middle of my cross cable, which works fine, I assume that the termination is not really necessary on both sides when having just a one meter cable.
