 34    description: |
 35      Defines the 8 physical delivery channels on the controller that can
 36      be referenced by PSE PIs through their "pairsets" property. The actual
 37      port matrix mapping is created when PSE PIs reference these channels in
 38      their pairsets. For 4-pair operation, two channels from the same group
 39      (0-3 or 4-7) must be referenced by a single PSE PI.
