From the project
Western Electric 1D/2D Payphone Controller for Asterisk
The coin relay in most payphones operates using +/- 130VDC. This project uses a DC-DC converter to boost 12VDC to 130VDC. Construction and operation of this circuit should only be performed by people familiar with best practices when operating with high voltage, and using extreme caution.
