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
