WIRE PAIR VERIFY TEST
In this test mode you will check the inside wiring for room audio that could
be present if a microphone is attached to one of the wire pairs. Technically,
this would not be a wiretap, but a bug. However, the result is the same – your
confidential information is passed on to a listening post.
1.
Set the Mode switch to “
Verify”
the Pair switch to “
R-G
” and turn on the
Volume to about midrange.
2.
Move the
Pair
switch through all six positions while listening to the audio
output. It’s a good idea to play a radio or TV in the target room while doing
a sweep. This gives you a known sound source, it will also turn on sound
activated bugs. If you hear room audio or a feedback squeal from the test
set, it is an indication that a microphone is attached to one of the wire pairs.
3.
Leave the TT-46 connected and perform the
Driver
test.
WIRE PAIR DRIVER TEST
In this test you will apply voltage to each pair to turn on voltage operated
devices such as FET (Field Effect Transistor) microphones. Again, these are
not wiretaps, but bugs.
1.
Turn the Mode switch to “
Driver
” the Pair switch to “
R-G”
Test switch to
“
Test 1”
and the Volume to midrange.
2.
Press the
PTT
switch and listen for room audio or feedback squeal.
Release the
PTT
switch and move the
Pair
switch to the next position.
3.
Do step 2 for each position of the Pair switch. When all six pairs have
been checked, return the
Pair
switch to the
R-G
position.
4.
Set the
Test
switch to
Test 2
and repeat steps 2 and 3.
5.
Disconnect the TT-46 and return the inside wiring to its normal condition or
go on to the Series test described next. If you got an indication of a parallel
tap or bug, go to the pages on locating wiretaps.
SERIES TAP TEST
In this test, you will be checking each wire pair for a series (in line) tap.
Follow the steps listed below.
1.
At the protector block or TNI make sure the inside wires are disconnected
from the phone line as discussed earlier and short all four lines together.
This can be done by connecting all four wires to the same binding post and
tightening the nut or screw.
2
. Set the TT-46 switches as follows: Mode to
“Series”
Test to “
Test 1”
Pair to
“
R-G”
Volume to “
Off”
. Connect the TT-46 in turn to each inside wiring
connection point. It is important to run the test at each jack so that each leg
or branch is tested. This was not necessary in the
Parallel
test since all
branches or legs are automatically tested in parallel.
