Good distinction.  What you're describing sounds more like the RedFone
device which is actively parsing, processing, and routing the digital
media stream of a T1/E1, using a digital switching system not a
mechanical one.  I imagine that in your field of broadcasting, there
would be little tolerance for artificats introduced a mechanical switch.

The Rhino is just a passive (normally closed) mechanical switch with an
active monitoring system.  The advantage is that it can be used to do
failover on switch Ethernet, Analog or ISDN.  You couldn't get that kind
of flexibility otherwise.  

Thanks!
