Noise (Hum) on line after install

[jnl636]

I use equipment at home that automatically records telephone conversations. It triggers with a VOX switch and starts recording when the phone is picked up. Since getting DSL installed there is so much noise on the line that the recorder won't shut off. Keeps recording before a phone is even picked up.Has anyone had any trouble with noise on there lines?

Do you have a DSL filter installed between the phone line and your device?
The filter is supposed to eliminate DSL noise from non-DSL devices on the line.
I would try that first.

I've put filters on all lines. I even disconnected all phones and DSL and its still there on the lines. It showed the same day the DSL was activated. It sounds like a 60hz from powerlines.

Since you have a filter between the line and your recorder I would suspect the wiring change to connect DSL to your line was done poorly, perhaps a strand of wire touching ground or a loose connection, either at the Central Office or at the neighborhood hub. ATT tech supp. can test for that quickly by remote control. Call 'em.
