5.5.3 String and Dual String Topology with Termination

The String and Dual String Topologies support both termination and non-termination. A String or Dual String
network with termination is the same as a String or Dual String topology, except a "loop-back" connector is
added to the last node(s). The advantage of using a terminator on the last node is that the network ini-
tialization time is reduced, because the controller can deterministically find the last node on a network.
