It puts an impedance across the xmit and receive pairs. Without
which the ring interface will drop the phantom drive signal and
de-insert.

I can't imagine why you couldn't BUILD such a device, crossing
over the appropriate wiring pairs and putting the proper
impedance (balanced) across the leads to fake out the cable
fault detection.

Hey, look at who came up with the idea.....you expect cheap from
IBM? >:-)
