Phone Line Simulator - DC Loop Current and AC Ring Voltage Experiments

PCBWay Supports High Precision Advanced PCBs: https://www.pcbway.com/ This experiment involves setting up a DC current loop so phones or modems can come alive and interact without needing a landline service. Then an AC ring voltage is added to the simulated phone line so the phones or modems can ring when on-hook. This is the first step in a bigger project where more complete functionality will be added to the system. Schematic/Files: https://github.com/GadgetReboot/RJ_6P...
