How to programmatically reserve Internet access by a second provider on win 7?

Question

Windows

A computer on win7 is connected by wire to a router that already uses redundancy, with periodic access control to a given ip.

You need to set up redundancy with another channel, already at the computer level.
In addition to the router, a phone is connected to the computer in modem mode.

If the connection on the router still falls off, you need the Internet to go through this backup interface.

How to do this using windows tools or third-party software?
It is desirable that at the same time a ping with a given period occurs on the interface that has fallen off, and as soon as the connection is resumed, it returns to the first interface.

Answer 1

Well, if I were you, I would try to google "windows 7 backup channel" and take the first script that came across.
