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. 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.
