FEATURES

The TS17 Portable Test Telephone
employs the latest technology in integrated
circuit design to provide:

■ Talk and Monitor Modes.

■ Tone (DTMF) and Pulse Signaling.

■ Continuous Polarity Indication.

■ Audible Ringer.

■ Listening for noise.

■ High Impedance Monitor Mode.

■ Field Replaceable Line Cord and

Belt Clip on some models.

This portable test telephone, often called
a "butt-in”, is a self-contained, line
powered (no battery required), portable
handset used by installers, repair
technicians, and other authorized
personnel for testing and temporary
communications on metallic voice type
telephone lines.

CONTROLS AND INDICATORS

TALK/MONITOR Mode. The test

telephone has a two-position slide switch
located on the side of the handgrip near
the receiver. The switch is labeled TALK/
MONITOR.

In the MONITOR position, the TS17 is
on-hook with a 6K Ohms impedance
audio coupling to the telephone line. This
allows for telephone line monitoring
without disrupting conversations, or
network signaling. In this position, the
TS17 also places an audible ringer
across the line.

In the TALK position, the TS17 is off-hook
and may be used for dialing and talking.
In this mode, the TS17 performs as an
ordinary telephone.

Audible Ringer. The TS17 Test
Telephone has an audible ringer to
indicate incoming calls when the test
telephone is in the MONITOR mode.

PULSE/TONE Switch. This two-position
slide switch, labeled PULSE/TONE, is
located on the side of the handgrip, just
below the receiver. The switch selects the
dialing type: TONE for DTMF dialing or
PULSE for pulse dialing.

Note: The TS17 is not polarity sensitive
and will function normally regardless of
telephone line polarity.

Polarity. The red LED, located below the
keypad area, will light up when the red
test lead is connected to a more positive
voltage than the black test lead.

Keypad. All 12 dialing keys will send
DTMF tones. Ten of the 12 keys send dial
pulses. Asterisk (❋) and pound (#) will not
send dial pulses. If the asterisk (❋) key is
pressed when the unit is in PULSE mode,
the dialing mode will be changed to tone
dialing.

OPERATION

Monitoring. Move the TALK/MONITOR

switch to MONITOR and connect the test
leads to the telephone line under test.
Monitoring may now be done without
disrupting traffic. Typical monitoring
applications include:

■ Verifying that the line under test is idle

before going off-hook.

■ Hunting for trace tones.

■ Listening for noise.

If the telephone lines under test include
data lines, it is best to use the MONITOR
mode when hunting for trace tones to
reduce the possibility of interrupting a data
service.

Polarity Check. Move the TALK/
MONITOR switch to TALK. The red LED
will not light if the red test lead is
connected to the ring (negative) side of the
line and the black test lead is connected to
the tip (positive) side of the line. The red
LED will light if the test leads are reversed;
that is, with the red test lead connected to
the tip (positive) side and with the black
test lead connected to the ring (negative)
side.

Dialing

1. Move the TALK/MONITOR switch to
the MONITOR position.

2. Move the PULSE/TONE switch to
either PULSE or TONE depending on
the type of signaling required.

3. Connect the line cord clips to the
telephone line and verify that the
telephone line is idle.

4. Move the TALK/MONITOR switch to
the TALK position. Listen for dial tone
(when furnished).

5. Enter the desired number to be
called on the keypad. If the test
telephone is in the TONE mode, the
tones associated with each digit will
be generated as each respective
button is pressed. If the test
telephone is in the PULSE mode, the
digits will be pulsed out at the correct
rate as the keys are pressed.

6. To end the call, return the TALK/
MONITOR switch to the MONITOR
position.

MAINTENANCE

Belt Clip Replacement. The belt clip

may be easily replaced in the field
without opening up the Portable Test
Telephone. The ordering number for the
replacement clip is P1780002. To replace
the belt clip, follow the instructions that
comes with the belt clip.

Line Cord Replacement. The line cord
may be replaced in the field. The ordering
number for the line cord is P1780001. To

jack from the end of the TS17 Test
Telephone and replace the cord with a
new one.
