This is a short, 0 to 8 character, name for this node that appears at the top of the control terminal's menus and printed reports. Because this name shows up on every operator console session and report for this node, an admin sets it to something immediately identifiable, like a site abbreviation, so technicians working across a network of many similar nodes can tell at a glance which physical node they're logged into. For example, naming a node 'CHI-HUB1' instantly tells an operator this is the Chicago hub node rather than one of dozens of remote branch nodes.
