			(Redundant systems only.)
	Ports 0 to 7	Green	The following conditions exist:
			• The port is receiving the upstream heartbeat message regularly.
			• The heartbeat message indicates the CAP PIM has HEC alignment in the
			downstream direction.
			• The SLC has HEC alignment in the upstream direction.
			• The modems on both sides have negotiated the loop rates.
			The port LEDs remain lit (green) in the presence of occasional minor alarms.
		Flashing	The loop is rate-adapting (training).
