Phone Line Polarity - 05/02/09 01:47 PM
I have a modular phone line tester that is telling me my lines are reversed polarity (red light), but the phone and my DSL modem are both working. When I test the line out on the back of my DSL modem I get a circuit ok (green light). Is it a normal occurrence for a home phone line to be wired in reverse, and does it take away from the quality of the connection?
To say I’m an amateur at of phone lines and wiring is putting it mildly, I wasn’t aware of the issue until I self installed a jack in my bedroom to a bare line coming out of the molding, by way of downloaded instructions from Lowe’s. I’m trying to hook up a second DSL modem in my room, but don’t want to go to all the effort if it isn’t going to work properly because of the reversed polarity issue.
Will just reversing the red & green solve the problem? Or do I need to start from the source and make the corrections from there?
Any HELP will be greatly appreciated.
