1. 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 illustration on page 19 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 point2. and in the Verify mode a rushing noise will be heard in the speaker or earbud A modulated IR beam will also cause signal to increase In addition some type of audio will be heard in the Verify mode Depending on the type of modulation you will hear either baseband audio or some type of tone High speed data above an audio rate will give a rushing sound P 03 LINE DRIVER PROBE SPECIFICATIONS Current Limited to 8 mA maximum Input impedance 8K Ohms Indications Red LED Lights when more than 1 4 volts AC or DC is present on the wire pair under test Green LED When the Line Driver switch is operated this LED glows if 400 uA or more is being drawn by the wire pair under test The more current that is drawn the brighter the LED will grow Controls LINE DRVR OFF This switch applies a voltage to the wire pair under test to turn on voltage activated microphones CAUTION Never push the Line Driver switch on if the Line Driver LED is RED This indicates a voltage present on the wire pair Pushing the line driver while there is a voltage on the line will damage the P 03 and TD 62 Any damage caused in this fashion will not be covered under the product warranty The use of a digital multimeter or other voltage indicating device is highly recommended before connecting the P 03 to any wire pair A B This switch reverses the polarity of the line connections for detecting DC voltages and for reversing the polarity of t

B C and D on page 27 Itis 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 3 At each connection point push and release the PTT switch for each position on the Pair switch Before leaving one connection point for the next repeat the tests with the Test switch in the Test 2 position For each pair the Series LED should glow green when the PTT switch is pressed If it is red for any of the tests this means the loop resistance is over 10 ohms and is an indication of a series tap 5 Return the inside wiring at the protector block or TNI to its normal condition reconnect each wire to its proper place Reconnect your telephones answering machines etc to return your system to normal HOOKSWITCH BYPASS TEST VERIFY MODE This test lets you check your telephone for hookswitch bypass tampering In this test you will use the dual modular coupler Phones without modular plugs can be tested using the in line coupler and modular cord with alligator clips 1 On the TT 46 set the switches as follows Mode to Verify Test to Test 1 Pair to R G and Volume to midrange 2 Unplug the telephone to be tested from its wall jack and plug the dual coupler into the jack in its place Then plug the phone into one jack of the dual coupler and the TT 46 into the other jack 3 Lightly tap the phone hous
