Hi Armin! I guess the RJ-45 jack with the resistor must be connected to the DIVA card, right? But I'm still confused. Usually, if a line needs termination, the termination is needed on both ends. Thus, if there is no line termination inside the DIVA card, we would termination in TE mode too. regards klaus _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
