What are these N64 controllers from?

I spotted this on Yahoo Japan. Seems to be pairs of N64 controllers sharing a singular button on a control box that plug into a phone jack which is fed into a PCB or some sort of electronics system. Could this be from an airline or hotel system for playing games remotely?

Pretty sure they're for a hotel system, like the lodgenet ones.

 

Was there a rival to lodgenet? I have a lodgenet controller somewhere and im pretty sure it has the same plug.
Would be great if someone could actually piece together a working system instead of just finding all these controllers.

 

Lodgenet hotel system, they had the same for gamecube as well

 

Great thanks guys. Just a lodgenet variation then.

 

I never got to take advantage of any hotels that used this. I came across a few when I was a kid, but my parents were never exactly accepting of video games.

 

Quite an interesting find.

 

My trip to the US back in 1996/7 had Lodgenet. It was crazy expensive, my parents just said 'forget it'.

 

We had a few snes ones in Australia at some point but im not sure what company did them.
Mum and dad flat out refused their prices too though they were pretty exorbitant rates.

There was still one in MA that had this when I stayed 4 years back.
