Scheduling：
The WAN disconnection schedule will be activated by checking this
option. In some areas, there is a time limitation for WAN connection
service. For example: the optical fiber service will be disconnected from
0:00 am to 6:00 am. Although there is a standby system in the device, at
the moment of WAN disconnection, all the external connections that go
through this WAN will be disconnected too. Only after the disconnected
lines are reconnected can they go through the standby system to
connect with the Internet. Therefore, to avoid a huge number of
disconnection, users can activate this function to arrange new
connections to be made through another WAN to the Internet. In this
way, the effect of any disconnection can be minimized.
Line-Dropped Period：
Input the time rule for disconnection of this WAN service.
