AT-MC606 VDSL Network Extender Installation Guide

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.
