Full Duplex Mode - Nortel 2033 Installation And Operation Manual

Full Duplex mode

In the Configuration menu, Auto Negotiate mode is the default setting for
initial startup. Typically, the IP Phone is connected to a network that supports
Auto Negotiate, and it selects the best speed and duplex mode available.
There is no intervention required under normal operation.
Note: Changing the speed and/or duplex mode on the phone changes
both the LAN Ethernet port and PC Ethernet Port interfaces.
It is recommended that Auto Negotiate 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 will result.
If the IP Phone is connected 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 67 to enable Full Duplex mode.
