The DWDM node type is determined by the cards that are installed. For example, if two
32DMX-O and two 32MUX-O cards are installed but no AD-xC or AD-xB cards are installed,
CTC considers the node a hub node. However, if one 32DMX-O and one 32MUX-O card are
installed with no AD-xC or AD-xB cards, CTC considers the node a terminal node. For more
information, refer to Chapter 14, "Card Reference."
