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.
