components on a different subnet. If configured on the DHCP server, use option 3 for the Default Gateway and option 1 for the Subnet Mask. Contact your network administrator for the proper settings for your network.

NetLink Wireless Telephones cannot roam with uninterrupted service between subnets unless specific LAN components are present. Certain AP/Ethernet switch combinations establish a layer-2 tunnel across subnets that enables the handsets to roam. Without this capability, any call in progress will be dropped when the user moves out of range and the handset must be power cycled in order to resume functionality in the new subnet area.

Ensure that all your access points are attached to the same subnet for proper operation. The handset can change subnets if DHCP is enabled and the handset is powered off then back on when within range of access points on the new subnet.

Please see Best Practices for Deploying Enterprise-Grade Wi-Fi Telephony for detailed configuration information.

Subnets are not recommended in NetLink Telephony Gateway environments.

Syslog Server IP The IP address of the syslog server. See section 6 Diagnostic Tools for more information.

ESSID

Select the option that will enable the handset 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 Guide for your access point or call your access point vendor for specifics. Overlapping wireless systems complicate the use of ESSID learning as the handset in an overlapping area

could receive conflicting signals. If this is the situation at your site, use or in an area without overlapping ESSIDs.

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.

*Learn Once Allows the handset to scan all ESSIDs for a DHCP server and/or the NetLink Telephony Gateway. Once either is found, the handset retains the ESSID from whichever access point it associates with at that point. When overlapping wireless systems exist, the Learn Once feature allows the handset to use only the ESSID established at first learn at all subsequent power ons. This ESSID is retained by the handset until the ESSID option is reselected.

Learn Always Allows the handset 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 handset will be used at more than one site.

Security

*NONE Disables any 802.11 encryption or security authentication mechanisms.
