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.
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.
IMPORTANT:
The connection hunting feature is only available on USR3520 WCDMA + CDMA
IMPORTANT:
When using the USR803520 base unit (this is the version without CDMA technology),
you don't have to select the wireless operator. The device uses the
UMTS Generic
setting.
