Understanding Spectralink Phone Software
Architecture
The Spectralink handset software is made of four basic components:
Updater
The software that loads & runs first when the handset is powered on
Spectralink Software
The software that implements the handset functions and
features
Configuration files
The files that contain the handset
’s parameter settings
Resource files
Optional files that contain settings for advanced features

What is the Updater?
The Updater is a small application that resides in the flash memory on the handset. The Updater
is installed at the factory and is already installed on your new Spectralink handsets.
When you start/boot/reboot the handset, the Updater performs the following tasks:
1
Enables you to open the setup menu so you can set various network and provisioning
options.
The Updater requests IP settings and accesses the provisioning server (also called the
boot server) to look for any changes to the Updater software.
If updates are found, they are downloaded and saved to flash memory, which overwrites
itself after verifying the integrity of the download.
2
If new updates are downloaded, the Updater formats the file system, removes any
application software and configuration files that were present.
3
Downloads the master configuration file.
The Updater and the application use this file to acquire a list of other files that the
handset needs.
