Introduction
The model TG-50 Tone Generator is a highly practical
network installation and troubleshooting tool which fea-
tures a single or multi-tone signal, two test leads and a
4-conductor modular cable. The signal emitted by the
Tone Generator can be easily traced by the Probe, even
when cables are bundled or hidden in a punch down
block or wall plate. The Tone Generator & Probe can be
used to verify cable continuity, identify wiring faults,
determine line polarity and voltage in network (CAT 5
and Coax) and modular telephone lines. The TP-20
Probe is equipped with a tone amplifier and an LED indi-
cator that detects audible frequency tones for accurate
tracing and identification of wires.

1. Slide the toggle switch to the “TONE” position
2. Connect the test leads to the subject pair
3. Using a handset or headset at the remote end, touch the
wire end(s) with the clip lead(s)
4. Reception of tone is an indication of continuity
• All above tests are applicable to modular plugs for line 1 only (red &
green wires)
Modular Testing
• To send a tone on un-terminated coaxial cables, connect the RED test
lead to the outer shield and the BLACK test lead to the center conduc-
tor, or connect the RED test lead to the outer shield and the BLACK test
lead to ground
• To send a tone on terminated coaxial cables, connect the RED test lead
to the connector housing and the BLACK test lead to the center pin, or
connect the RED test lead to the connector housing and the BLACK test
lead to ground
Coax Testing
The TPG-70 includes the TG-50 Tone Generator and TP-
20 Probe in the kit.
