DSX-4K DS3 Front Cross-Connect Solution ADC's DSX-4K provides exceptional density with up to 36 terminations in a front cross- connect style panel. Individual modules can be added as needed and include dual, non- intrusive monitor ports and patent-pending adjustable rear BNC connectors. Backed by ADC quality, manufacturing excellence, and exceptional customer service, this high-density system enables patching, terminating, and rearranging of circuits in central office or network edge applications. Features: • 36 termination front cross-connect chassis • Dual, non-intrusive access points for bidirectional monitoring • 75 Ohm auto termination on cross-connect interface • Patent-pending adjustable rear BNC connectors • Innovative rear tie-down bar with lacing holes • Quality cable management support and design • Supports DS3 (44.736 Mbps) to STS-3 (155 Mbps) signal rates www.adc.com • +1-952-938-8080 • 1-800-366-3891 8/01 • 100490PR DSX-4K Front Cross-Connect 2 DSX-4K Front Cross-Connect Products The DSX-4K was designed with increased density and functionality over the standard DSX front cross- connect products. The front interface includes dual, non-intrusive monitor ports which save technicians time by allowing bidirectional monitoring of a circuit from a single test access point. The patent-pending adjustable BNC connector on the backplane allows the connections to be located closer together for higher density. This system slides and locks the BNC connector into position and maintains easy network cabling access. And with these close tolerances, the DSX-4K maintains signal isolation between adjacent modules. The front cross-connect panel provides the density and flexibility needed in networks requiring front-access solutions.
