administrator for the proper settings for your network. Note that the Wireless Telephones
cannot “roam” across subnets, since they cannot change their IP Address while
operational. Ensure that all your access points are attached to the same subnet for proper
operation. The Wireless Telephone can change subnets if DHCP is enabled, and the
Wireless Telephone is powered off then back on when within range of access points on
the new subnet.
ESSID
Select the option that will enable the Wireless Telephone to acquire APs with the correct
ESSID (Extended Service Set ID, aka SSID) each time it is turned on.
Note about Automatic Learn options: Broadcast ESSID must be enabled in the access
points for ESSID learning to function. Refer to the Configuration Note for your access
point or call your access point vendor for specifics. Overlapping wireless systems
complicate the use of ESSID learning as the Wireless Telephone in an overlapping area
could receive conflicting signals. If this is the situation at your site, use Static Entry or
Learn Once in an area without overlapping ESSIDs.
* Learn Once: allows the Wireless Telephone to scan all ESSIDs for a DHCP
server and/or TFTP server. Once either is found, the Wireless Telephone retains
the ESSID from whichever access point it associates with at that point. When
overlapping wireless systems exist, the Learn Once feature allows the Wireless
Telephone to use only the ESSID established at first learn at all subsequent power
ons. This ESSID is retained by the Wireless Telephone until the ESSID option is
reselected.
Learn Always: allows the Wireless Telephone to automatically learn the ESSID
at each power on or loss of contact with the wireless LAN (out of range). This
may be useful if the Wireless Telephone will be used at more than one site.
Static Entry: If your access points do not accept broadcast ESSID or if there are
overlapping wireless systems in use at the site, enter the correct ESSID manually.
License Management
License Management lets you select the VoIP protocol that your site is licensed to
download and run. The MiNET protocol to use for the NetLink e340/i640 Wireless
Telephones is 014. Any other protocol will cause the Wireless Telephone to malfunction.
After selecting the correct protocol for your site, you should upgrade the software for the
Wireless Telephones. See the Upgrading Wireless Telephones section for more
information.
Restore Defaults
The Restore Defaults option will set all user and administrative parameters to their
factory defaults.
Site Survey Mode
Site Survey Mode is used to check the signal strength from access points. When you
select Site Survey Mode, the Wireless Telephone will remain in this mode until it is
powered off. See the Certifying the NetLink e340/i640 Wireless Telephone section for
