5.5 Use case 5 : The machine is connected through the factory & a cellular ntwk
Description
Reaching the Internet through the factory network may not be immediately authorized or available at the
moment of the machine installation; it is the reason why, the router RAS (RAS-EC or RAS-ECW) is able to
select the available way to the Internet; the factory network access to the Internet is selected as a priority
and the cellular network is used as a backup solution. The router RAS switches automatically between that
both ways.
