6.3.1 Performance Mode (Always Connected)
This mode allows 3G/3.5G USB dongle to keep at the connected status. The power consumption is huge
under this mode. System will keep detecting if 3G/3.5G USB dongle is connected; In this mode, the
trigger condition is disable.
6.3.2 Backup Mode
3G/3.5G USB dongles wil be in power saving state, which the system will provide low power for USB
interface. The system will keep detecting the wired network status and traffic. If the wired network is
disconnected, 3G/3.5G USB dongle will provide the network connection at any time. When the wired
network is back, 3G/3.5G USB dongles will return to power saving state.
When the WAN connection is detected failed, the traffic will transfer to USB:
A. Trigger Condition:
When ALL the chosen wired connections are detected failed
You have to choose at least one WAN port; When there are multiple WAN ports chosen, the system will
transfer the traffic to 3G/3.5G dongle when all the chosenwired connections are detected failed.
B. Return condition:
When ALL the chosen wired connections are detected back, the system will return 3G/3.5G USB dongles to
power saving state.
* Take the figure above, which user clicks both WAN 1 and WAN 2, as example: When the system detects
both WAN 1 and WAN2 are disconnected, 3G/3.5G USB dongles will be the backup for the wired network.
When WAN1 and WAN2 both return to connected, 3G/3.5G dongles will return to power saving state as
well.
