Use the Configuration -> Backbone function (on the pop-up menu for a valid resource) to display a view that contains the resource and hosts, communications controllers (PU types 4 and 5), and subarea transmission groups that make up the backbone of your network.
If a backbone view exists, the view is automatically opened and displayed. If more than one view exists, the topology console displays a list of views you can open.
Note: This function applies only to RODM resources.
