Default Re: "New exchange" from Norwegian STK (=STC)

Now I got the C.O. line working to.
Grounding button needed on the phone, and that connects to C.O. line. (both incoming and outgoing calls)
The 2 B connections are for a DC 24V ringer.
(The only one I have is a fire alarm ringer so that was loud )
