Hey guys
Im looking for the diagram to connect the aux sig, ring supply and talk battery to my 551B Switchboard. I moved and stuff got disconnected. She was working flawelessly last year, But for the life of me I cant remember which terminals to connect the ring supply too and talk battery too
Thanks.
