The D1M-1B0005-L is an 84-termination rear cross-connect panel with bantam jacks. This panel has additional temporary wiring installed between the cross-connect tip and ring pins. This creates an automatic circuit loopback, which can be removed when semi-permanent cross-connect jumpers are installed. The panel includes two 4-inch x 4-inch (10.2 cm x 10.2 cm) vertical jumper rings, horizontal cable tray, red LEDs, and a designation label numbered 1-84. The panel can be mounted flush or with a 2-, 3-, or 4-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. ***Photo shown represents typical product likeness, but may differ from actual product catalog number listed here.
