    Component specifications for the Leviton 4x12 Telephone Distribution Panel with 8-Way Splitter (47603-412) — combines telephone line distribution with an 8-way 2GHz video splitter in a single bracket.

    Overview

    Leviton's 4x12 Telephone Distribution Panel combines a 4x12 Telephone Line Distribution Board and an 8-Way Video Splitter in a dedicated plastic bracket for essential telephone and video distribution. It handles up to four telephone lines through 12 telephone connections, making it suitable for phone, fax, or modem, while the panel's video output supports up to 8 video connections. Links with other distribution boards, modules, or panels to expand the system.

    Features

    • 12 modular RJ-45 jack outputs for telephone distribution
    • 4-pair 110-type IDC inputs
    • 1x8, 2GHz video splitter with gold-flashed F-connectors and tin-plated zinc die-cast housing

    Design Considerations

    • Fits easily into any Leviton Structured Media™ enclosure, or can be used as a stand-alone unit
    • Determine outlet locations and carefully plan cable routing to ensure the selected panel satisfies requirements; additional Category 5e Voice and Data Boards available separately
    • Install 75 Ohm termination caps on unused outputs of the 8-way video splitter to reduce signal distortion ("ghosting")
