TLDR
In this paper, a decoding network establishes a direct link from the user to control circuitry for the intended subsystem by sequentially decoding call or address signals initiated by the user and transmitted over a single pair of wires.Abstract:
A system is disclosed for selecting and controlling any one of a number of remotely-located, controllable subsystems. A decoding network establishes a direct link from the user to control circuitry for the intended subsystem by sequentially decoding call or address signals initiated by the user and transmitted over a single pair of wires. Once the link from the user to a particular control unit selected has been established, the connection remains secure until broken by the user; and subsequent control signals actuated by the user select and control the desired function of the remote subsystem.read more
