Tone Generators

Network Cable and Port Identifier

Traditional Tone Generators were designed for one primary mission; to identify the termination point of a cable. Most toners on the market offer RJ-11 hard-wired modular connection. That's because they were designed mostly to be used in the Telecommunication market. This does nothing for the LAN technician who is faced with Ethernet RJ-45 jacks or patch cords. The CableTracker Tone Generators were designed to accommodate both Computer Network cabling and Telephony cabling. There are 2 types of Tone Generators:

  • The CableTracker CT10 Tone Generator traces cables with two different tone frequencies and patterns.  The CT10 also identify cable termination ports by  blinking the LEDs on the switch.
  • The CableTracker CT12 Ultra High Power Tone Generator is up to 10 times more powerful than other generators and traces tone signals on high performance twisted pair, coaxial and even shielded cables. It also test continuity for Opens, Shorts and High Resistance Shorts.

The CableTracker Network Tone Generators are designed for network managers and technicians. Toning an active LAN circuit can disrupt network traffic and is difficult to track due to cable twist and tone bleed.

The CableTracker CT10 has a traditional toning method with two different tone frequencies and patterns for non-active circuit tracing. The CableTracker CT10 features a Port ID function that blinks the link light verifying cable connectivity. This feature also provides a simple and effective method to identify switch or hub port assignments on active networks. Three different blink rates are provided to ensure compatibility with equipment from a wide range of manufacturers.

The Ultra High Power CableTracker CT12 Tone Generator enables signal detection on cables miles away and makes hearing a tone through walls, ceilings and enclosures easier with a power level far greater than other tone generators. The amazing 190mWatts of output power reduces maintenance times by making it easier to trace and identify cables used in Network, CATV, Audio/Video, Security and Telephone applications.  The unit has a continuous run mode and an Auto power down mode to conserve battery life. Quick continuity test allows the CT12 to detect Open, Shorts and High Resistance Shorts between the test leads to verify the wire is good.


The CableTracker Tone Generators are designed to accommodate both Computer Network and Telephone cabling.
