Filter installation: DSL modem and phone share the same jack If you need to connect your modem and a phone device into one jack, you'll need a High Speed Internet filter and a 2-for-1 jack (included in your installation kit) to complete your setup.

Remember: Installing filters on your phone devices is Step 1 of the Verizon High Speed Internet installation process. You need to install filters on all phone devices using a telephone line before installing your modem.

  1. Plug the 2-for-1 jack into the wall.

  2. Plug your modem into one side of the 2-for-1 jack.

    Important: Do not install a filter on your modem.
