How Do I Connect My Phone to My ONT Box?

Published in Phone Connection 2 mins read

To connect your phone to your Optical Network Terminal (ONT) box, you'll need an RJ11 cable.

Here's how to do it:

  1. Locate the RJ11 Cable: This is a standard telephone cable with smaller connectors than the RJ45 cables used for Ethernet.

  2. Connect to the Wall Jack: Plug one end of the RJ11 cable into the main phone jack on your wall. This is the jack that typically provides your phone service.

  3. Connect to the ONT Box: Locate the TEL/PHONE port on your ONT box. This port is specifically designed for connecting your phone line. Plug the other end of the RJ11 cable into this port. The TEL/PHONE port is often labeled with a phone icon or the word "TEL."

That's it! Your phone should now be connected to your ONT box and ready to make and receive calls.

Troubleshooting:

  • If you don't have dial tone, double-check that the RJ11 cable is securely connected to both the wall jack and the ONT box.
  • Ensure your ONT box is powered on.
  • If problems persist, contact your internet/phone service provider for assistance. They can help diagnose any potential issues with your ONT box or phone service.
