7.2.4: Telephone wires, Tracing and Finding Faults
The floating method is usually used to locate a pair of wires
in a telephone junction block. If the wires are already termi-
nated into a modular telephone jack, simply plug the FOX or
FOX 2 into the jack. This method works with the phone line
connected or disconnected from the wires going to the tele-
phone company. A stronger trace is usually obtained if the
wires are not connected to the telephone company.
If the wires are not connected to the telephone company,
the grounded method can be used to trace telephone wires
through a wall or ceiling. Use the green and red clips to con-
nect to the phone line and ground.
To identify the wires, if using the floating method and a FOX
2, momentarily short the suspect wires together to active
True Trace, and listen for the cadence change. If it changes,
you’ve found the target pair. If no change occurs, keep
searching.
To identify the wires, if using the grounded method and a
FOX 2, momentarily short the suspect wire to ground to ac-
tive True Trace, and listen for the cadence change. If it
changes, you’ve found the target wire. If no change occurs,
keep searching. This will not work if a fake ground is being
used. An actual ground is required to activate True Trace.
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.
