the 3G-WAN USB port on the rear side of the device, and then plug the 3G USB modem
into the USB modem extension cable-mount slot. This enables you to dial a wireless call
to the 3G wireless service provider network, which acts as an Internet gateway. To use
the 3G USB modem as a backup interface, you can use the dialer feature available in the
