Full Duplex Mode - Nortel 1110 Fundamentals

130 Nortel IP Phone 2004

Full Duplex mode

In the Configuration menu, autonegotiate mode is the default setting for
initial startup. Nortel recommends that autonegotiate mode is used on the
network and the IP Phone. Use Full Duplex mode only when the network
is forced Full Duplex for 100BT Full Duplex mode; otherwise, a duplex
mismatch results. No intervention is required under normal operation.
Changing the speed and changing the duplex mode on the phone changes
both the LAN Ethernet port and PC Ethernet Port interfaces.
Nortel recommends that autonegotiate mode is used on the network and the IP

100BT Full Duplex mode; otherwise, a duplex mismatch results.
If the IP Phone connects to a network configured for Full Duplex mode
only, the IP Phone cannot automatically negotiate the proper configuration.
Therefore, in this instance, to allow the IP Phone to work at the optimum
speed and duplex mode, Full Duplex mode must be enabled.
