TOP !!! (ISDN + TAE-U)

Pity me this Dosenart is not already noticed a few years ago ... In my house we only use actually DECT to make phone calls. And at the base of Anrunfbeantworter is already installed. So I need the TAE doses barely. TAE-N certainly not.
However, the ISDN bus is used by me in several places in the house. With this box, I can use both in one place, if I want to.

The TAE-U can has a U-niversaldose and thus suitable for the F and N connectors.
