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 disconnections, users can activate this function to arrange
new connections 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 the disconnection of this WAN service.
Line-Dropped
