Well, you take a DMM and find out what voltage is on the jack end of the
pair. If it is zero, proceed to next step. If you get some voltage
like 48 volts, then it probably already has dial tone, and all you do is
hook up a phone and dial someone's cell phone to find out what the
If you get zero volts, then check to see that it is open circuited,
hopefully not a bad cable pair. Remember that people disconnect the
phone line at the central office, and seldom mess with the wiring in the
panel. So you will be mearsuring the whole line back to the CO. Then
when you've determined that it's open, put a 9V battery on the jack end.
Go to the panel with the DMM and poke around, and you should find zero
on the lines not connected, 48 or so volts on the lines that are
working, or if someone is on the line, some voltage near the 9V. And if
you find almost the same 9V that is at your battery, you should have
found the line you're looking for.

The usual is to get a jack that fits a duplex outlet. Then go to the
Big Orange Box hardware store and buy a weatherproof cover for the
outlet. Or else, go to Graybar and buy an outdoor Network Interface or
whatever they call it. Rat Snack also used to have those. See URL

In any case, the best place to ask these questions is comp.dcom.cabling.
You have to connect up to the line, so make a biege box by putting
alligator clips on the end of a modular cord. Then test for
conversation while your friend is on the phone.
