Nice collection!
Have you got your payphone working?
I have an idea about a 16 kHz tax pulse system used in Germany, Denmark and Norway. Pretty tricky to build.

Thanks!

The payphone works without the 16 Khz pulse, i can input the money and then can dial but no money is pay, when you put off the handset comes the complete money back. You can only dial with money, not without money. You find a video from this clubtelephone on my youtube telephone channel:

You find in my channel many other telephone videos, from Germany but also from US and a few other

The call proceeds and the coins are returned because there is no reversal from the exchange. Without it, the call is treated as a free call.

Normally, when a chargeable call is made, there is a reversal when the called party answers. Once that happens, there is a 16kHz collect pulse that takes an initial unit charge. If the call is timed, periodic collect pulses are received. More expensive calls receive collect pulses more often.

If there are no coins when the collect pulse arrives, the call is terminated. Some phones will make a sound and give a short period of grace before the call is terminated.
