description: |

|
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.
