Hello,
I'm about to connect an ADSL modem to my phone line, but I have an old, pulse-dialling wall phone in another room, which I assume will interfere with the modem, so it has to be disconnected or a filter attached. I took the cover off and the cable has four wires, two pink and two yellow, attached to a board, each with a quick-connect connector. They aren't easy to get at, so I want to know what the minimum required is to disconnect it. That is, how many of the wires and how do I determine which ones? I have a volt meter.
