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.
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 106 “Enabling Full-duplex mode for IP Phones 2000 Series
and IP Phones 1200 Series” (page 415)to enable Full Duplex mode for IP
Phone 2001, IP Phone 2002, IP Phone 2004, IP Audio Conference Phone
