Abstract: A multilocation private line selective signaling system is arranged to generate privacy lockout tones when a first station at any location goes off-hook. The first such off-hook station is designated a controlling station and circuitry at each location responds to the lockout tones by removing signaling and communicating capability from all but the controlling station. Communication capability is extended only to those stations signaled by the controlling station and busy tone is returned to any off-hook station which has not been given such capability. Each location is arranged with circuitry for controlling data transmission between stations and for preventing any station from interfering with the data.

Abstract: A multiline selective signaling system is arranged to generate privacy lockout tones when a first station on any line goes offhook. The first such station off-hook is designated a controlling station and circuitry at each station or common to a group of stations responds to the lockout tones by removing signaling and communicating capability from all but the controlling station. On interline calls single station control of the system is maintained by an interline control circuit which is arranged to inhibit the first station going off-hook in a called line from also becoming a controlling station. On interline override calls dialing capability is removed from the interference with previously established called line connections.
