Keypad Controls and Indicators
B HI Z/RING/TALK Switch: This three-position slide
switch is labeled as HI Z for high impedance
monitoring, RING for ringer and low impedance
monitoring, and TALK for talk.
• In the HI Z position, the TS19 is on hook with a
high impedance coupling to the telephone line.
This allows for telephone line monitoring without
disrupting conversations, data or signaling.
• In the RING position, the TS19 is on hook with an
electronic ringer connected to the telephone line.
The TS19 is low impedance coupled to the line for
monitoring of optional line identification tones.
Also, the TS19 provides enhanced receive levels.
• In the TALK position, the TS19 is off hook and may
be used for dialing and talking. In this mode, the
TS19 performs as an ordinary telephone.
C PULSE/TONE switch: This two-position slide switch
labeled PULSE/TONE, is located on the inside of
the handgrip just below the receiver. The switch
selects the signaling output. TONE for DTMF of
PULSE for dial pulse.
Keypad Controls and Indicators
See Figure 3.
Keys: The 12 standard keys
will send either DTMF tones
or dial pulses, depending on the PULSE/TONE switch
setting.
Polarity LED: This red LED is located
just below the
keypad. The LED indicates polarity (see “Polarity
Check”). 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.

Cords
See Figure 4.
The TS19 comes with either a standard cord or an
angled bed-of nai
ls cord (see B and D below). The line
cord can be replaced in the field (see “Line Cord
Replacement”).

Figure 4. Line Cords
Various cord types may be ordered for field
replacement:
A Piercing Pin Cord: This cord is equipped with a
modular plug on one end, and has two five and
one half foot long fabric covered leads, one red
and one black. Each conductor is fitted with an
alligator clip offset 20 degrees to minimize clip
shorting. The clips have insulation piercing spikes
and a neoprene boot. Cord Number: P1980001.
B Banana Jack Cord (STD): This is the standard cord.
This cord is equipped with a modular plug at one
end and two banana jacks at the other with
alligator clip adapters. Cord Number: P1980003.
