LED Color Description

PWR
GREEN Power is applied to the unit.
OFF Power is not applied to the unit.

10Base-T/100Base-TX Ethernet Port

LINK/
ACT
Solid GREEN A link has been established on the port.
Blinking GREEN Network traffic is being transmitted and/or received.
OFF A link has not been established.
100M
Solid GREEN Port is linked at 100 Mbps.
OFF Port is linked at 10 Mbps when LINK/ACT LED is solid or
blinking GREEN.

Coaxial VDSL LINE Port

SCBR/
PROV
Solid GREEN Unit is configured as a Subscriber Unit (SCBR).
OFF Unit is configured as a Provider Unit (PROV).
LINK
Slow Blinking
GREEN
VDSL is idle when blinking occurs approximately
1 time/second.
Fast Blinking
GREEN
VDSL is in the training or handshake mode when the blinking
occurs approximately 3 times/second.
Solid GREEN VDSL has established a connection with its link partner.
Rapid Blinking
GREEN
VDSL activity is occurring when the blinking occurs
approximately 6 times/second.
OFF VDSL link is not established.
RATE Blinking GREEN
After a VDSL link is established, the Rate LED indicates the
data rate being received on the BNC port. It will continuously
blink a set number of times in a set time interval. Each “blink”
represents approximately 10 Mbps of VDSL line rate (e.g.,
six “blinks” represents a VDSL line rate of 60 Mbps). The
data rates on both the Provider unit and Subscriber unit are
approximately the same when configured for the SYM
(symmetrical) mode and differ significantly when both are
configured for the ASYM (asymmetrical) mode. See“VDSL
Configuration DIP Switches” on page 22 for more
information.
