I would like to build a power supply to simulate the ring signal on the telephone line. I can switch it manually, so I really just need an AC power source that generates approx. 90-110 V. AC and has a frequency of 20 Hz. I need this for testing modems in remote locations to see if they will answer. This should also be a low current device so it doesn't burn up the modem. Any help would be appreciated. Thanks.
