You can easily built those yourself. It's nothing else but a handful of
Reed Relays that, when power is off, cause a cross-connect between the
two external plugs, and when power is on, provide a normal feed to the
jack.

A couple relays, two RJ-45 jacks, to RJ-45 plugs and a small universal
circuit board is all you need (besides some skillz handling a solder
iron...).

Cheers,
Frank
