LED
Description
Power
Solid GREEN to indicate the unit is powered on.
VLINK modem
Link
(Active Green) Solid green (ON) to indicate that the
end-to-end VDSL link between the VLINK modems is
established. The VLINK modem LED is OFF when
the link is down.
VLINK modem
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 modem Link
LED extinguishing.
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 VLINK modem’s 10/100Base-T Ether-
net port.
