operation. The wireless handset can change subnets if DHCP is enabled,
and the wireless handset is powered off, then back on, when within range
of APs on the new subnet.
• Server 2 IP – the IP address of the secondary Nortel Networks device.
Currently, the wireless handset does not make use of this information. If
using Static IP configuration, this is simply the IP address of the device.
If DHCP is being used, the wireless handset tries to obtain the device's
IP address and port information using the following DHCP options:
46, 128, 144, 157, 191, and 251.
• Server 2 Port – the port number used by the secondary Nortel Networks
device to communicate with IP phones. Currently, the wireless handset
does not make use of this information. If using Static IP configuration,
consult the device's documentation for port numbers. If DHCP is being
used, the wireless handset tries to obtain the device's IP address and port
information using the following DHCP options:
43, 128, 144, 157, 191, and 251.
Select the option that enables the wireless handset to acquire APs with the
correct ESSID (Extended Service Set ID, or Extended SSID) each time it is
turned on.
With regard to Automatic Learn options, Broadcast ESSID must be enabled
in the APs for ESSID learning to function (or contact the AP vendor for
specifics). Overlapping wireless systems complicate the use of ESSID
learning, as the wireless handset in an overlapping area could receive
conflicting signals. If this is the situation at the site, use Static Entry or Learn
Once in an area without overlapping ESSIDs.
• * Learn Once
DHCP server and/or TFTP Server. Once either is found, the wireless
handset retains the ESSID from whichever AP it associates with at that
point. When overlapping wireless systems exist, the Learn Once feature
allows the wireless handset to use only the ESSID established the first
time at all subsequent power-ons. This ESSID is retained by the wireless
handset until the ESSID option is reselected.
