- Ahh, the wonderful folks from C&P telephone and their quality demarc boxes.
- What's happened is that there is current leakage between the ground and your
- phone line someplace. Could be that the demarc box is getting wet. Could
- be that the lines in the house are getting wet someplace. Disconnect the
- line at the demarc next time it gets bad and plug a phone into the box...
- if you can still hear a hum, call C&P and place a report with the craftsmen
- and make sure someone is there to explain that it's a ground imbalance
- problem when the guy arrives.
-
- If it's inside the house... well, you're going to have to start pulling
- things apart to locate the problem. Could be anything from a bad phone
- to wet wiring.
