Know More About Triplett Telephone Line Tester

What is Telephone Line Tester?

Telephone line testing tools are basic devices in use since analog phones networks were established across cities and countries. However, these tools have evolved with the advent of digital phones and advancements in electronics. They are simple to use for any lineman or telecom repairs professional. We offer various models and types of phone line testers which can check anything from a basic dial tone, signal, caller ID, last number redial, and flash button to DTM and FSK support, 3-level volume control without battery, testing POTS lines and systems, telephone jacks, LAN jacks, and so much more.

How to Use Phone Line Tester?

This phone line tester is used to check any issues with phone lines such as polarity, current or new line installations, and so on. Our modern testers are quite easy to use. While the function and method of testing would slightly vary with the type and requirement, here are some relevant pointers regarding their usage.

  • Connect the testing tool to the phone line using a modular connector. Some of our models are suitable for both RJ45 and RJ11 plugs.
  • On the tester, there are LEDs in green, red, yellow or amber colors, which serve as indicators. As always if the signals or lines are fine, green light will be lit. In case of any issue, the red light will be up.
  • In case the voltage range is as required, the green light will go up which indicates the voltage is at least above 40 volts in case of direct current.
  • They can call from a back ring number to test the telephone functioning. If it is normally ringing, the LED will pulsate which implies the AC ringing voltage and current levels are fine.
  • You can check the load resistance and loop voltage in the same manner.
