+      Defines the 8 physical delivery channels on the controller that can
+      be referenced by PSE PIs through their "pairsets" property. The actual
+      port matrix mapping is created when PSE PIs reference these channels in
+      their pairsets. For 4-pair operation, two channels from the same group
+      (0-3 or 4-7) must be referenced by a single PSE PI.
