I recently acquired a "never installed" Ernest Telecom D3 payphone and I would like to use it in my home. I have it open and have tried connecting it to my line but it refuses to respond in any way.
The battery was dead on the smart board and I have replaced it.

I would like to find any documentation, wiring diagrams or advice on how to get it operational.
At this point I would be happy to hear a dial tone!

Please advise. Thanks!
