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.

ATTENTION

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.

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.

Use Procedure 13 “Enabling Full Duplex mode” (page 87) to enable Full

Duplex mode.
