The DMM system allows a permanent, dedicated connection between two NEs while providing dual, nonintrusive test access points for bidirectional monitoring of the network signal. Ensuring unsurpassed quality, this interconnect solution features cable management designed to increase reliability, maintain signal flow, and allow easy cable identification. To enhance network flexibility, the DMM system allows modules to be installed in a chassis as network requirements increase. Features: • Provides bidirectional, nonintrusive signal testing • Supports E1 (2.048 Mbps), E3 (34.368 Mbps), or STM-1 (155.52 Mbps) signal rate applications • Modular design allows for capital investment to coincide with revenue growth • Mounts in standard 600 mm bays • Quality cable management and circuit identification markings Digital Monitor Module System 75 Ohm Interconnect Designed as a flexible solution for network signal management, ADC’s Digital Monitor Module (DMM) system provides a centralized coaxial termination and interconnection point between network elements (NE).

Each NE is semipermanently cabled to IN/OUT connectors in either the front or rear of each module. The digital signal is accessed through the two MON OUT connectors on the front of each module for testing and monitoring. These dual monitor ports allow access to both directions of the circuit from a single location. This saves valuable technician time when the other side of the termination is located far away, in another room, or is inaccessible. 12/06 • 103978AE Digital Monitor Module System Network Network Element A DMM Element Z OUT MON Tx OUT MONZ-OUT IN Rx IN Tx OUT OUT Rx IN IN A-OUT Test Unit 2• +1-952-938-8080 • 1-800-366-3891 12/06 • 103978AE Digital Monitor Module System Digital Monitor Module System 75 Ohm Interconnect Configurations The DMM system is available in several chassis and rack configurations to create a customized interconnect solution. Each module is ordered separately and may be installed in any DMM chassis or rack configuration as the network expands, allowing capital investment to coincide with revenue growth. Modules Multiple connector interface types and locations are available to complement existing network designs. Individual modules allow chassis to easily match existing NE circuit counts. Standard Configuration Up to 12, 24-position chassis are designed to mount in a standard 600 mm rack for a total of 288 circuits. Cable management bars, trays, and labeling are provided on each chassis. High-Density Configuration This uniquely designed dual chassis features two separate compartments, each accommodating up to eight modules mounted horizontally. The two compact compartments are mounted side-by-side in a specially designed dual-column 600 mm rack. This high-density configuration allows a total of 352 circuits in one rack. Cable management bars and four vertical cabling ducts ensure proper routing for high-density cabling. Wall-Mount Box This six-position enclosure serves as an interconnect demarcation point between network providers and customers. Separate locks on each door secure connections from unwanted access. 3www .adc.com • +1-952-938-8080 • 1-800-366-3891 12/06 • 103978AE Digital Monitor Module System Digital Monitor Module System 75 Ohm Interconnect Modules Features: • Front, dual monitor ports on all module styles • BNC or 1.6/5.6 connectors provide true 75 Ohm characteristic impedance • All module styles are compatable with any DMM 600 mm chassis style Description IN/OUT Connector Locations Catalog Number BNC Rear DMM-BBNCMF BNC Front and Rear DMM-BBNCF BNC Bulkhead Front and Rear DMM-BNCBLK 1.6/5.6 Rear DMM-1656MF 1.6/5.6 Front and Rear DMM-1656F 1.6/5.6 Bulkhead Front and Rear DMM-1656BLK Blank None DMM-BLANK Ordering Information DMM-BBNCMF DMM-BBNCF DMM-BNCBLK Rear and Front View Rear and Front View Rear and Front View DMM-1656MF Rear and Front View DMM-1656F DMM-1656BLK Rear and Front View Rear and Front View 4www.a...
