Long phone cord.
Before the glorious days of cell phones and cordless phones, all telephones needed a wire to connect themselves to the telephone line. Cords are made of copper and covered in plastic with four small cables weaved together, and with special connectors designated as 4P4C and RJ11. The small cables inside must be placed in the plug in a certain order. Only two of the cables are actually used for communication, but if a second line is required, the other two are used as well.
Primarily used by corded telephones or as improvised garrote wire.
