Always On versus On Demand

When the modem is set in Always On mode, it performs as a separate entity in

relation with the wireless network. Thus, the modem is managing its own connection

and an attached host must use the modem as a point of access to the wireless

network.

When set in On Demand mode, the modem is no longer in autonomous connection

mode. Connection management in that case is performed by an attached terminal. The

most common scenario is to use the serial port in order to establish a PPP session.

Test your connection

Once the process above is completed, go to File > Diagnostic: you should see the valid

modem’s WAN IP displayed, this is the IP address that has been assigned to the

modem by the wireless carrier.

At the same time, you should see the modem’s LNK light solid ON.
