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.
