Device Management System

Device Management - How It Works

Device Profile Type created on Application Server� Defines the Access and Configuration Profile

settings for the Device.

� Container for Device Template files

� Parent Instance for Device Profiles

Device Profile is created on Application SIP NOTIFY (sync/reset)

HTTP GET

HTTP PUT

Templates FilesConfiguration Files

Device Profile is created on Application Server and Assigned to User.� Device Profile represents the physical device

� Device Management builds files replacing tags in template files with user data

� Built files are pushed to Profile Server

Device Initialized on Network� Downloads files from XSP via HTTP(S)

� Use username/password for authentication

� Device Restarts via SIP NOTIFY from Application Server

HTTP(S) GET

Service Integration

Device Template files are created with Device Management Tags� When files are built the Device

Management tags are replaced with service data for the user.
