Cat3 48 Port Patch Panel – RJ11 6P/4C USOC – 110 Block

Category 3 Voice Patch Panel — 48 Port, 3U RJ11 / 110 Punch-Down

The Category 3 48 Port Patch Panel is a high-density voice distribution solution designed for telephone, PBX, and legacy telecom installations in standard 19-inch racks. With 48 RJ11 ports in 3 rack spaces, this panel provides a centralized, professional way to organize and terminate analog voice lines in telco closets, equipment rooms, reception areas, dormitories, and call-center environments.

Each port uses RJ11 6-position / 4-conductor jacks with USOC wiring terminated to a rear 110 punch-down block, allowing fast, reliable installation without soldering. This makes it easy to terminate, label, trace, and reconfigure voice circuits while keeping your rack layout clean and serviceable.
