Overview
Metropolis
®
DMXplore allows operation and maintenance of network
elements in a network from a centralized location. Metropolis
®
DMXplore continuously monitors the equipment and incoming
signals, and reports any current or potential troubles. This monitoring
enables the user to take the appropriate preventative or corrective
action.
Types of maintenance
Metropolis
®
DMXplore supports proactive and reactive maintenance.
Proactive maintenance
Proactive maintenance refers to the process of detecting degrading
conditions not severe enough to initiate protection switching or
alarming, but indicative of an impending failure.
Proactive maintenance consists of monitoring performance parameters
associated with SONET (for example, OC-N) sections, lines, and
paths within the network and monitoring non-SONET (for example,
DS1 and DS3) lines and paths.
Reactive maintenance
Reactive maintenance occurs after a failure. The LEDs on a circuit
pack faceplate report internal troubles. Most troubles can be detected
and corrected at this level. The optical network (ON) craft interface
terminal (CIT) or TL1 interface may be used to retrieve detailed
reports about alarms and conditions. Metropolis
®
DMXplore can also
be configured for a standard IEEE 802.3 TCP/IP interface.
