I am trying to help a friend here in Cincinnati Ohio move his small business, and after setting up his computer network he asked me to take a look at the phones. He has a WIN 36D that he brought with him from the old building and I would like to ask if someone in this community might have a copy of the wiring diagram or installation manual for this. I would like to help my friend out but have never wired a pbx.

Thank you in advance for any assistance you may provide.

Peace be with you.
