 Nortel IP Phone 1140E

553-3001-368 Standard 26.00 August 2007

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.

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 74 to enable Full Duplex mode.

Double-press the Services key to open the Local

 

Tools menu.

Press 3 on the dialpad to access the Network Configuration menu or 
use the Up/Down navigation keys to scroll and highlight the Network 
Configuration option.

Use the Right navigation key to scroll and highlight the Duplex combo 
box.

Press Enter to start the edit mode. 

Press the Down navigation key to open list box.

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.
