The D1M-1F0016 is an 84-termination front below cross-connect modular panel with bantam jacks. The panel includes two 4-inch x 4-inch (10.2 cm x 10.2 cm) jumper rings, horizontal cable bars, a horizontal cable tray, red LEDs, and a designation label numbered 1-84. The panel mounts flush or with a 2-inch recess in a 23-inch (58.4 cm) rack. The 84-termination panel is primarily deployed with equipment configured in multiples of 28 and can terminate up to three M1/3 multiplexers or one OC-3 multiplexer. Some key features and benefits of the D1M-1F0016 are: Die-cast Bantam jacks are rigorously tested with over 10,000 insertions/withdrawals, Superior cable management designed into each panel, LEDs flash at both ends of the monitored circuit for 30 seconds, Cross-connections are located below the jacks on the front of the panel, Guarantees reliability, durability, and quality over time, Simplifies cable routing and circuit identification for growing and changing networks, Quick identification of cross-connected circuits, and Integrated horizontal cable trough enables cable management along the panel.
