@alsamavo: ISDN-Telefone sind zunächst schnurgebundene digitale Telefone, die bislang an einen NTBA angeschlossen sind. DECT -Telefone sind zunächst schnurlose Mobilteile. Diese benötigen aber eine DECT -Basisstation, die wiederum schnurgebunden ist und die es für Analog- aber auch ISDN-Anschlüsse gibt.
Wenn Du bisher einen ISDN-Anschluss mit einem "echten" ISDN-Telefon hast, das an den NTBA angeschlossen ist, und Du das weiterhin benutzen willst benötigst Du einen Router (FRITZ!Box 7490 ...) mit einem ISDN-S0-Port, d.h., mit einem internen NTBA.
Wird kein ISDN-Telefon benötigt, kann Du einen Router mit interner DECT -Basisstation nehmen (Speedport Smart) an dem Du dann DECT Mobilteile wie die Speedphones oder Gigaset HX anmeldest.
War das verständlich?
