INFINITY CABLING

Standard telephone installations normally require ONE PAIR for each telephone, so a cable is selected to suit the job ex. 22 phones use 30 pair with some spare pairs for additional telephones which may be added. PLEASE NOTE some telephone systems use TWO pairs for each phone ie voice & data

Basic Tone Generator Operation

INFINITY CABLING

The probe will amplify all signals detected on cable including voice conversation, noise, data etc. This may cause the generated tone not to be heard.

Tone Generator Transmits a data word over and over

Magnet Field around Cable

Amplified Probe Detects data word and turns on green Sync light. As the probe gets physically closer to cable being searched for an audio tone is generated and signal strength lights turn on.
