53 All the CTI devices are associated with a CTM. On many systems there will be a
54 single effective CTM (one CTM, or multiple CTMs all interconnected), but it is
55 possible that systems can have nets of CTIs+CTM that are not interconnected by
56 a CTM to each other. On these systems a CTM index is declared to associate
57 CTI devices that are interconnected via a given CTM.
