Users Guide
C Ground Start Cord: This cord consists of two
conductors with alligator clips. In addition, the red
(ring) conductor has a banana jack attached. This
jack is located six inches below the Portable Test
Telephone and is partially covered by the outer
fabric of the cord. A separate cord is also included.
This cord is 36 inches long with a banana plug on
one end and an alligator clip on the other. Cord
Number: P1980007.
D Angled Bed-of-Nails Cord (ABN): This cord is
similar to the standard cord (STD), except that
each alligator clip is equipped with a “bed-of-
nails” and an insulation piercing spike. Cord
Number: P1980009.
Operation
WXWarning
When connecting to metallic network wires,
always handle alligator clips by the
insulated boots.
Monitoring: Move the HI Z/RING/TALK switch to HI Z
and connect the line leads to the telephone line under
test. Monitoring may now be done without disrupting
traffic.
Polarity Check: Move the HI Z/RING/TALK switch to
TALK. Connect the line leads to the telephone line
under test. The red LED lights if the red test lead is
connected to the Tip (positive) side and the black test
lead is connected to the Ring (negative) side.
Dialing:
1 Move the PULSE/TONE Switch to PULSE or TONE,
depending on the type of dial signaling required.
Move the HI Z/RING/TALK switch to HI Z. Connect
the line cord clips to the telephone line. Listen to
verify that the telephone line is idle.
2 Move the HI Z/RING/TALK switch to TALK and
verify that dial tone is received (when finished).
Enter the desired number to be called on the
keypad. If tone signaling is selected, the tones for
each digit are generated as each key is pressed. If
rotary dial pulse signaling is selected, the desired
number may be entered at any rate on the
keypad; digits will automatically be pulsed out at
the correct rate. To end the call, move the HI Z/
RING/TALK switch to the HI Z position.
Last Number Redial: The last number dialed can be
automatically redialed with the PULSE/TONE switch set
to PULSE or TONE. Use the following procedure for a
number up to 18 digits long:
1 Go on hook (move the HI Z/RING/TALK switch to
the HI Z position) for at least ½ second.
2 Move the HI Z/RING/TALK switch back to the TALK
position.
3 Press the LNR button and the number will be
automatically redialed.
Note
The redial memory has a 15 minute time limit
after the Portable Test Telephone has been
disconnected from a working telephone line.
After 15 minutes, the number will be lost from
memory.
Electronic Ringer (On/OFF): Move the HI Z/RING/TALK
switch to RING and connect line leads to the telephone
line. The piezo-electric transducer electronic ringer will
“ring” whenever it detects ringing voltage on the line.
Answer the call by moving the HI Z/RING/TALK switch
to TALK. To disable the ringer, move the HI Z/RING/
TALK switch to HI Z.
Troubleshooting
The following troubleshooting procedures are based
largely on the audible click heard in the receiver of the
TS19 when the two Portable Test Telephone leads are
placed on battery potential and ground respectively, or
across the terminal of an electrically charged capacitor.
These clicks and other sounds can help you locate open
circuits, shorts, crosses, and grounds.
