In Facilities, you access information relating to buildings, terminals, cables, pairs, and the working service supplied by those cable and pairs.  The navigation pane displays four sub-menus: Buildings, Connections, and Sites. 

Within this document, the order of the menu options does not match the order within the software.  This is because when you are creating your facilities you have to start by adding your sites, then your connections and finally your buildings.  Therefore, we cover Sites first followed by Connections and Buildings.
