What failures are you trying to protect against? One of the WIC modules?
I really don't see how much good you are going to accomplish. First, my
experience
would say that a FR failure would be far more likely than a router
component failure.
Second, both FR lines are presumably in the same cable back to the CO, and
equally
subject to backhoe fade. Even if you get FR from different providers, there
still will
be local components unless you can guarantee they will be on separate local
loops --
a very expensive proposition.
If you could get a CATV connection, or wireless broadband, you actually
might be
redundant.
