This read-write object represents the active-port state for each of the CC group's 10 output ports, per the description referring to a "CC 10 output port Group." Admins configure it to control which of the ten composite-clock output ports in the group are currently active and distributing the timing signal. For example, if only 6 of 10 downstream devices need a clock feed, an admin would set this object to activate just those 6 ports and leave the rest inactive.
