VERY interesting. I'd guess that the cable was miswired on both 
ends, with the transmission circuits improperly split between 
twisted pairs of the CAT5. Such a cable would pass a simple 
continuity test, but would not perform well with data. 

Nonetheless, the common mode mechanism I cited in the earlier post 
is a VERY common one.
