Of these simple devices have three connections: power adapter is connected to an electrical outlet, 4-wire dial-up connection when you plug your standard telephone equipment and the Ethernet adapter to connect the device to your network. The adapter converts (digitizes) the analog phone signal to the IP protocol.
