The LED’s are as follows:
PWR
Power. This indicator lights when the ON/OFF switch is in the ON position.
BTG
Booting. This indicator lights when the MultiFRAD is booting.
Composite Link
RCV
Receive. This indicator blinks when the composite link is receiving data.
XMT
Transmit. This indicator blinks when the composite link is transmitting data.
CD
Carrier Detect. This indicator lights when the MultiFRAD detects a carrier signal.
CTS
Clear To Send. This indicator lights when the composite link device is ready to transmit
data.
V35
V.35 Interface. This indicator lights when the composite link is configured for a V.35
interface.
EXT
External Link. This indicator lights when the MultiFRAD is configured for an external
composite device.
LNK
Link. This indicator lights indicating that the MultiFRAD is connected to the local area
network. It will blink slowly when management frames are detected, quickly when at least
one, but not all, pvc’s are active, and will light solidly when all pvc’s are active.
Ethernet
RCV
Receive. This indicator blinks when packets are being received from the local area network.
XMT
Transmit. This indicator blinks when packets are being transmitted to the local area
network.
COL
Collision. This indicator lights when a collision is in progress; that is, when two nodes are
transmitting packets at the same time.
LNK
Link. This indicator lights indicating that the MultiFRAD is connected to the local area
network.
Channels 1 and 2
V35
V.35 Interface. This indicator lights when the channel is configured for a V.35 interface.
XMT
Transmit. This indicator blinks when the channel is transmitting data.
RCV
Receive. This indicator blinks when the channel is receiving data.
Channels 3 through 10
XMT
Transmit. This indicator blinks when the channel is transmitting data.
RCV
Receive. This indicator blinks when the channel is receiving data.
