Abstract: A method and apparatus is disclosed for selectively connecting network devices 22, 24 to a local area network 26. The apparatus and methodology of this invention 10, enables the devices 22, 24 to be connected to controllers 12, each of which have an output to a uniquely associated multi-station access units 14 and which allows the devices 22, 24 to be individually and selectively connected to the access unit 14. More particularly, the method and apparatus of the invention includes two computers 18, 12 which use voltage signals to selectively connect devices 22, 24 to access unit 14.
