This is basically a technical question (I think.)
I am getting DSL, and intend to connect the modem to the telephone jack next to my computer. There's a problem: there's a two-line phone connected to that jack, and "Line 1" is a telephone number I want to discontinue, and "Line 2" is the number I am setting up for DSL.
Today, it occurred to me to test that jack with a single-lne phone, since the modem will have a single line connector. When I plugged the single-line phone into the jack, it automatically connected to the "Line 1," on which I want to discontinue servie, instead of line 2, which is being set up for DSL.
Will I have to pay to have that jack rewired, or is it likely that, once "line 1" service is discontinued, the modem jack will automatically connect to the remaining "Line 2" instead of reporting "no connection?"
