There are two Ethernet ports on the rear of the IP phones: LAN Port and PC Port. Using the Mitel Web UI, you can select
the type of transmission you want these ports to use to communicate over the LAN. The IP phones support each of the
following methods of transmission:
• Auto-negotiation
• Half-duplex (10Mbps, 100 Mbps, or 1000Mbps [if applicable])
• Full-duplex (10Mbps, 100 Mbps, or 1000Mbps [if applicable])
Auto-negotiation
Auto-negotiation is when two connected devices choose common transmission parameters. In the auto-negotiation
process, the connected devices share their speed and duplex capabilities and connect at the highest common denomi-
nator (HCD). Auto-negotiation can be used by devices that are capable of different transmission rates (such as
10Mbit/sec and 100Mbit/sec for the 6863i and 1000Mbit/sec for the 6865i, 6867i, and 6869i), different duplex modes
(half duplex and full duplex) and/or different standards at the same speed. You can set the LAN and PC Ports on the IP
phones to auto-negotiate during transmission.
Half-Duplex (10Mbps , 100Mbps, or 1000Mbps)
Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the
same time. For example, on a LAN using a technology that has half-duplex transmission, one device can send data on the
line and then immediately receive data on the line from the same direction in which data was just transmitted. Half-
duplex transmission implies a bidirectional line (one that can carry data in both directions). On the 6863i IP phone, you
can set the half-duplex transmission to transmit in 10Mbps or in 100Mbps. For the 6865i, 6867i, and 6869i IP phones, you
can set the half-duplex transmission to transmit in 1000Mbps.
Full-Duplex (10Mbps , 100Mbps or 1000Mbps)
Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.
For example, on a LAN with a technology that has full-duplex transmission, one device can be sending data on the line
while another device is receiving data. Full-duplex transmission implies a bidirectional line (one that can move data in
both directions). On the 6863i IP phone, you can set the full-duplex transmission to transmit in 10Mbps or in 100Mbps.
For the 6865i, 6867i, and 6869i IP phones, you can set the full-duplex transmission to transmit in 1000Mbps.
Configuring the LAN Port and PC Port
You can configure the Ethernet port transmission method to use on the IP phones using the configuration files, the IP
Phone UI, or the Mitel Web UI.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section, “Network Settings” on pageA-7.
