  • Before you begin, make sure you have the following:
  • - A landline phone
  • - A cable modem with phone line ports
  • - An active internet connection
  • - Ethernet cables

02Step 1: Check Compatibility

  • Ensure that your cable modem is compatible with phone line connections. Check the modem's specifications or user manual to confirm if it supports landline phone connections.
  • If your modem does not have phone line ports, you may need to consider purchasing a separate adapter or upgrading to a modem that supports phone line connections.

03Step 2: Connect the Phone Line

  • Take one end of an Ethernet cable and plug it into the phone line port on the cable modem.

04Step 3: Test the Connection

  • Once the phone line is connected, pick up the landline phone and check for a dial tone.
  • Make a test call to ensure that you can make and receive phone calls successfully. If you encounter any issues, double-check the connections and refer to your modem's user manual for troubleshooting steps.
