Phone jack testing

Is it possible - if you have no landline phone service subscription - to
test phone jacks? Would there be any voltage trickling in or.....?

There shouldn't be any voltage,
but things can get miswired.
Check for voltage (AC then DC)
between all wire pairs at the
phone drop into the house, and
between each and a good earth
ground.

If you don't find any voltage,
you can do a continuity test on
the jacks: go around to all jacks,
and measure the resistance. They
should all read open, if no phone
equipment is attached.

If you get a low resistance,
something is causing a short, and
you'll have to disconnect each
wire run at the breakout box to
find which circuit the short is on.

Then, short the terminals on one
jack, and go around to all the
others to measure for a low
resistance. If any jack still
reads open, it's not connected.

Testing for what?
Check for voltage first, then open ohm pairs then individually twist
the remote end pair together and ohm again.
