What is an ONT?
The ONT, or Optical Network Terminal, is the device that connects your local network to Sonic’s fiber optic network. Similar to the modem used by Cable and DSL connections. While Sonic uses several models of ONT, each ONT will have several core features- a power input, a Fiber Optic Input and Ethernet and Phone Jack output. ONTs do not have included Wi-Fi or network routing capabilities, so you will need either to rent a Wi-Fi router or gateway from Sonic or purchase your own.
