Hands Free Activation
Hands-Free Activation (HFA) is a series of client-initiated commands performed when the device is powered on in
a factory default state. The device is considered to be in the factory default state when any of the following
conditions are true:
•
MSID is default (000-000-xxxx)
•
MDN is default (000-000-xxxx)
Applications can reset the device to the factory default state by sending the $RTN command.
The transactions below are performed in the order listed during HFA:
1.
Client-initiated Device configuration
2.
Client-initiated PRL update
3.
Client-initiated FUMO

Session establishment
Device management sessions can be established by the OMA-DM Server using a Notification Initiation Alert
(NIA). The NIA is sent in the payload of a WAP-encoded SMS message. The NIA will be processed immediately if
the device is not in an active data session.
In general, the message payload consists primarily of a server account identification pointing to a server account
preconfigured in a DM tree node (tree.xml file).
If a data session is active, the LISA/FW75-C200’s DM Client will store the NIA until it can be executed. The
conditions required for execution are:
•
The current data session has moved to an idle or dormant state (i.e. the traffic channel is idle)
•
The modem is on either a home or roaming signal.
It should be noted that the dormant data connection will be torn down when the device process the NIA.
