The Map Browser of the Service Assurance Manager Global Console displays the optical network nodes and physical connections in a graphical view. An example is shown in An example of the physical map :
For Optical Transport Manager, network nodes are instances of the OpticalNetworkElement class. The physical connections between them are instances of the TopologicalLink class in both high and low order SONET/SDH domains or the FiberLink class in the WDM domain.
The Map Browser graphical representation would be too complex to show every one of the optical network objects. In order to reduce the number of objects that are imported into SAM for display to a manageable number, objects between the OpticalNetworkElement and the TopologicalLink or Fiberlink are not imported to the SAM model and are not displayed.
