11.1 Upgrading NetLink Wireless Telephones

After software updates are obtained from SpectraLink, they must be transferred to the appropriate location in the LAN to update the code used by the handsets.

NetLink e340/h340/i640 Wireless Telephones allow over-the-air transfer of software updates from the designated TFTP server to the handsets. The downloader function in the handset checks its software version every time the handset is turned on. If there is any discrepancy the handset immediately begins to download the update.

Normal download messages

When the handset is powered on, it displays a series of messages indicating that it is searching for new software, checking the versions, and downloading. The normal message progression is:

Message

Description

Checking Code	Handset is contacting the TFTP server to determine if it has a newer version of software that
	should be downloaded.
Erasing Memory	Handset has determined that a download should occur and is erasing the current software from
	memory. This message also displays a progress bar. When the progress bar fills the display line
	the erase operation is complete.
Updating Code	Handset is downloading new software into memory. The number icons at the bottom of the
	display indicate which file number is currently being downloaded. This message also displays a
	progress bar. When the progress bar fills the display line the update operation is complete on

When the update is complete, the handset displays the extension number, and is ready for use.
