System information

382 Features
Soft keys You can assign a maximum of nine functions to the four
soft-labeled, predefined soft keys. Because the soft keys are predefined,
the user cannot change the key number assignment. Functions are
assigned to the soft keys in layers in LD 11.
The Message Waiting key is numbered 16.
Functions mapped to key numbers 17 to 26 are assigned to the four soft
keys. Labels for the soft keys appear in the display area. For further
information, see “Context-sensitive soft key label” (page 344). Figure 61
"IP Phone 1150E display area" (page 343) shows the IP Phone 1150E
display area.
Key number mappings at the Call Server align with the IP Phone 2004.
For a description of the IP Phone function assignment for each soft key,
see “IP Phone context-sensitive soft keys” (page 605).

Full Duplex
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
