Tone Frequencies

577Hz :The TriTone Tone Generator offers the standard 577Hz tone typically used for identifing cable pairs on inside wire or outside plant. This tone is compatible with standard filtered and non-filtered tone amplifiers.

987 Hz :The TriTone Tone Generator also provides 987 Hz tone for compatibility with 987 Hz amplifier probes, and is easily distinguished in a two man restoration operation.

Simplex Mode

The Simplex Mode is preferred to quickly locate tone in large cables with a standard tone probe when working under normal situations with good cable bonding and grounding. Once the group is found the user detects a notable increase in tone amplitude when placing an amplifier probe tip close to the correct pair.

TriPlex Mode

When the cable conditions cause substantial tone bleed-over, making it difficult to determine the correct pair, TriPlex is recommended. In many cases Switching from Simplex to TriPlex eliminates any tone bleed-over to adjacent pairs. Given bleed-over is virtually eliminated it is recommended to initially locate the group using Simplex.

Tone Modes



The TriTone provides three tone levels. The Normal tone level should be used in most cases. Higher tone levels can be used when there is interference, long lines, or when identifying cables.
