the Ethernet port is set to 100 Mbps.
Half- and Full-duplex Mode
Duplex mode refers to the way an end-node sends and receives data on
the network. An end-node can operate in either half- or full-duplex mode,
depending on its capabilities. In half-duplex mode, data can be either sent
or received, but not at the same time. In full-duplex mode, data can be
sent and received simultaneously. The best network performance is
achieved when an end-node can operate at full-duplex, since the
end-node is able to send and receive data simultaneously.
The AT-MC606 VDSL Network Extender can Auto-Negotiate to either half-
or full-duplex mode, but cannot be manually configured to either mode. As
a consequence, the end node must also be operating in the Auto-
Negotiation mode for proper operation.
Note
For Auto-Negotiation to operate properly, the end-nodes connected
to the AT-MC606 should also use auto-negotiation. If an end-node
does not have this feature and has a fixed duplex mode of full-
duplex, the result will be a duplex mode mismatch with the end-
node. The AT-MC606 Ethernet port ends up in the half-duplex mode
if it is connected to an end-node with a fixed full-duplex mode. This
configuration can produce network performance problems. Should
you encounter this situation, you must configure the port on the end-
node to use Auto-Negotiation or, if it lacks that feature, to half-
duplex.
