Anyone know what this wire sticking out of my wall is?

Question

Moved into a new (but old) house recently and found this sticking out of my wall. Any idea what it is? Old telephone or radio wiring assembly?

First you drive your car into your new house, and then you plug that into the OBD-II port on the vehicle. ;) — RockPaperLz- Mask it or Casket, Dec 13 '21 at 06:39

That’s the cable and connector used between Verizon FIOS ONTs (mounted outdoors typically) and their indoors-mounted AC-DC power supply and backup battery.

The larger wires carry DC power (from either the AC supply or the battery); the smaller wires communicate status (power failure, battery missing, etc.) between the two units.
