LED	Description
Power	Solid GREEN to indicate the unit is powered on.
VLINK Link	(Active Green) Solid green (ON) to indicate that the
	end-to-end VDSL link between the Model 1068s is
	established. The VLINK LED is OFF when the link is
	down.
VLINK QOL	(Active Yellow) Flashes YELLOW to indicate the pro-
	cessor is correcting an error in the data thus prevent-
	ing the transmission of corrupted data to the Ethernet
	port. The more error corrections, the more often the
	LED blinks. If the light remains lit continuously, it
	means that the VDSL line is noisy—although the data
	at the Ethernet port remains uncorrupted. Further
	impairment of the line however, risks having the line
	fail, as indicated by the green VLINK Link LED extin-
	guishing.
Ethernet Link	(Active Green) Solid Green indicates that 10/
	100Base-T Ethernet link has been established.
Ethernet Activity	(Active Yellow) Flashes yellow to indicate Ethernet
	activity on the Model 1068’s 10/100Base-T Ethernet
	port.
