down the phone line to a listening
post even with the phone hung up.
This effectively turns the telephone
into a room monitor.
SCI-J1030 detects series devices
with a resistance of 61 ohms or
more. (Most series taps have a
resistance of over 100 ohms.) It
also detects parallel devices with a
resistance of 65 meg ohms or less.
(Most parallel taps are under 30
meg-ohms.) It can also detect
certain capacitively coupled taps.

telephone line and inside wiring;
usually just by unplugging a cable at
the interface box mounted on the side of
the building. There is nothing difficult
about this, but, of course, you must
have access to this interface box.
