SpectraLink 8002 Wireless Telephones Configuration and Administration (SIP)

30 PN: 1725-36034-001_B.doc

Domain Name System (DNS), an industry-standard protocol, locates

computers on an IP-based network. IP networks rely on number-

based addresses to move information on the network. However, it is

easier to remember friendly names than number-based addresses,

so it is necessary to translate user-friendly names into addresses

that the network can recognize. The handset will use DNS to

automatically translate names into IP addresses for the TFTP server.

In DHCP mode, the SIP handset will use DNS to look up an address

for the logical name “siptftp” to locate the SIP TFTP file server. If this

logical name is undefined, then the address specified by option 66 is

used for the SIP TFTP server.

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 APs for ESSID learning to function when multiple

ESSIDs can be seen by the handset from one location. 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 Static Entry or Learn Once in an area

without overlapping ESSIDs.

* Learn Once Allows the handset to scan all ESSIDs for a DHCP

server. Once either is found, the handset retains the ESSID from

whichever AP 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 in the Admin menu, thus erasing the stored

ESSID..

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.

Static Entry If the APs do not broadcast their ESSID, or if there are

overlapping wireless systems in use at the site, enter the ESSID

manually.
