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). 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

- Page 1 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). 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.
- Page 2 Digital Monitor Module System 75 Ohm Interconnect Application The DMM system is used primarily in co-location environments, DDF locations, and customer premises as a connection point between NEs. 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.
- Page 3 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.
