Is the use of fusable links in the cables legal?  As in UL etc?

What if the cable itself is incorrectly wired and the fusable link
is not in the right wire?  (The semi-standard bypass wiring includes
both signals intended to drive solenoids and wires just indicating
something is plugged in.  What kind of ethernet drop cable has 
fusible links?)
