The FRITZ!Box is optimally prepared for use with Init7. Simply connect the FRITZ!Box to the fiber optic connection and configure the internet connection in the FRITZ!Box. The complete FRITZ!Box range of functions for internet, telephony, and television (TV7) is then available to all of the devices in your home network without restriction.
