Abstract: The use of a group of relays, all having only make contacts interconnected in a manner to allow a single current pulse to selectively operate one relay while at the same time releasing all the other relays, has resulted in the design of circuits where a one-hot out-of-n code can be used to control the operational states of the circuits. The fact that the relays have remanent reed sealed contacts and are thus self-latching greatly simplifies minimumization of peripheral equipment and reduces control complexity since a single current pulse can both select the desired circuit state by operating one of the relays and release any other operated relay.

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.

Abstract: A group of timers, each having the characteristic of providing an immediate output voltage translation when an input goes from low to high and providing a delayed output voltage translation when the input goes from high to low, are arranged to detect the leading and trailing edges of a step input and to generate a step function having leading and trailing edges independently delayed from the respective leading and trailing edges of the detected step input. The delayed step function is supplied to another group of timers arranged to provide individually controllable pulse outputs in coincidence with the leading and trailing edges of the delayed step function.

Abstract: There is disclosed a line circuit for use in the path between a switching machine and a telephone station for controlling communication services such as ringing and hold to the station. The line circuit is connected across the communication conduction pairs in a manner which allows removal without interrupting active telephone service. The transient signals which are generated whenever the station makes a transition from on-hook to off-hook and from off-hook to on-hook are used to obviate the need for line current detection. In this manner, the line relay is removed from the series path between the switching machine and the telephone station.

CPC classification number: H04M9/006
Abstract: There is disclosed a line circuit for use in the path between a switching machine and a telephone station for controlling the hold function. The hold control circuit is arranged to respond to a momentary transient signal on the communication leads from the telephone station and to the presence or absence of a signal on the A lead from the station for establishing either the hold state or the disconnect state of the line circuit. Structure is disclosed for timing the release of the hold function on communication lead open conditions with the time delay dependent upon the insertion of a diode in series with the timing capacitor to adjust the voltage across the capacitor.

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.
