CONFIGURING LAN AND PC PORT NEGOTIATION
Ethernet is the computer networking technology for local area networks (LANs). You use the
LAN Port to connect to a LAN using a twisted pair 10BASE-T cable to transmit 10BASE-T
Ethernet. You use the PC Port to connect to the configuration server (your PC).
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 denominator (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, 6869i, and 6873i), 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.
Note: After connecting a device to the PC port, a reboot may be required before the
connected device can acquire network connectivity.
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,
6869i, and 6873i 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, 6869i, and 6873i IP phones, you can set the
full-duplex transmission to transmit in 1000Mbps.
