Leviton 47604-BTV Basic Telephone and Video Unit with SMC 100 Insert and Cover kit. Intended for new construction (or remodels) and gives you the installation box and the 47603-BTV module to go in it. The module combines a bridged telephone module and video splitter (1GHz). Handles up to four phone lines through to nine telephone locations and 6 video locations. We will include the construction rings with this (they are usually sold separately). The construction ring is installed before the drywall is put up and acts as a mount for the cover once the drywall is cut - the galvanized backer is snapped in place and becomes the mounting panel for the module.
