CALIFORNIA WARNING

Description:

Category 3 Voice Patch Panel — 48 Port, 3U RJ11 / 25 Pair Telco Connector
19-Inch Rack Mount • RJ11 4P2C • 25 Pair Telco Connector • Lifetime Warranty

The Category 3 48 Port Patch Panel is a high-density voice distribution solution designed for 2 wire 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 4-position / 2-conductor jacks with terminated to a rear 25 pair telco connector, 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.

Why this panel works well
  • 48 ports in only 3U — Packs high line count into a standard rack footprint for efficient telecom distribution.
  • RJ11 4P2C connectivity — Supports up to one voice pair per jack for single-line telephone applications.
  • 25 Pair Telco Connector Termination — Industry-standard rear termination for quick install, reliable connections, and easy service changes.
  • Clearly numbered ports — Simplifies labeling, troubleshooting, tracing, and future moves, adds, and changes.
Best-fit applications
  • PBX and key-system wiring — Centralized voice distribution in telecom rooms and equipment racks.
  • Analog phone installations — Great for reception desks, office suites, dorms, hospitality, and call-center environments.
  • Legacy telecom systems — Ideal for voice-grade structured cabling and older low-speed data applications.
  • Service-friendly rack layouts — Keeps voice terminations organized and easy to access in a single location.
