Introduction

The model TG-50 Tone Generator is a highly practical
network installation and troubleshooting tool which fea­tures 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 indi­cator that detects audible frequency tones for accurate
tracing and identification of wires.
