nect to the phone line and ground.
To identify the wires, if using the floating method, momen-
tarily short the suspected wires together while listening to
the FOX signal with the HOUND 3. If the FOX signal is com-
pletely killed (not heard on the HOUND 3), the selected pair
is probably the target pair. If the signal is not completely
killed, the wrong pair has been selected, or there is an open
fault in the pair, and crosstalk is being picked up from the
other wires.
To identify the wires, if using the grounded method, mo-
mentarily short the suspected wire to ground while listening
to the FOX signal with the HOUND 3. If the FOX signal is
completely killed (no heard any more on the HOUND 3), the
selected wire is probably the target wire. If the signal is not
completely killed, the wrong wire has been selected, or there
is an open fault in the wire, and crosstalk is being picked up
from the other wires. (This will not work if a fake ground is
being used. An actual ground is required to perform this
test).
An “Open Fault” may involve either one or both wires of a
telephone wire pair. Finding the open will only work if there
are no other faults (like a short to earth ground) in the pair.
If the pair is “live”, disconnect the pair from the incoming
telephone line before trying to locate the open. Short the
wires together at the far end and connect the shorted wires
to a good earth ground (a fake ground may not work well).
