WAN interface.

Radio firmware selection
Selects the wireless operator firmware the device will use on the network.
IMPORTANT: When using the USR803520 base unit (this is the version without CDMA technology),

If Verizon Wireless or Sprint is selected, the web interface jumps to the CDMA section. Click Start
Programming to provision the unit for CDMA.
If UMTS Generic is selected for T-Mobile or any operator not listed, you may be required to enter a
PIN code. In the PIN code section, enter the appropriate settings and click Save changes to provision
the unit for UMTS 3G.
If AT&T is selected, you may be required to enter a PIN code. In the Pin Code section, enter the
settings and click Save changes to provision the unit for AT&T 3G.
Connection Hunting
Connection hunting is a feature that allows the gateway to actively search for another network in case
the primary network is not available.
IMPORTANT: The connection hunting feature is only available on USR3520 WCDMA + CDMA
When enabled, a new section of the menu will appear allowing the user to select which other networks
the gateway should try to connect to in case the primary connection cannot be established.
The fallback time field allows selecting the time the gateway needs to try to connect to each of the
alternative networks before trying the next network.
