I'm glad I checked with Rhino on this point. My original understanding
was incorrect.  Bryce Chidester at Rhino said "The external port is to
be used *instead* of the internal header in the event there is no
internal header, or if you just want to mount the [failover
card]externally".  

I also learned that the name of this device is the "Single Port
T1/E1/J1, Ethernet and Analog Failover Card" sometimes referred to as
the SPF (single port failover) card.  I suppose it's so named because
even though it will failover 4 analog circuits, it will only failover 1
Ethernet or T1/E1/J1 circuit.
