The D1M-1A2017 is a 64-termination front split cross-connect E1 panel with bantam jacks and rear 1.6/5.6 IN/OUT termination, 120 Ohm. The panel includes red LEDs and designation labels 1-64. The panel uses ETSI (1.26-inch) mounting spacing and can be mounted with either a 2-, 3-, or 4-inch recess in a 19-inch (48.3 cm) rack. Some key features and benefits of the D1M-1A2017 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 on both sides of 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 Maximum panel circuit density in a front cross-connect style
