摘要： In an attachment apparatus for a key telephone system of the type which permits a plurality of intercom substations to access a trunk telephone line via a common communication circuit, a novel subset operable switching circuit is disclosed that permits each subset access to said common communication circuit only on an individual one-at-a-time basis. Transistor circuitry is provided to lock out other stations when more than one subset tries to gain access at the same time.

摘要： A key telephone system is arranged to provide access for any number of key telephone stations to any number of line circuits. When two or more stations are selectively connected to the same line circuit, the transmission capability of each such station is placed under control of a push-to-talk key at that station. The line circuit is associated with a selector for scanning each such connected station sequentially and for providing exclusive transmission capability to a first detected station having an operated push-to-talk key. On simultaneous connections to certain line circuits, the enabling of an override key at any of the connected stations provides unlimited transmission capability from that station without regard to the operational status of the push-to-talk key.

摘要： A method is disclosed that enables the managing of the overall sound level in an enterprise environment where telephones are used. A data-processing system such as a private branch exchange monitors whether one or more telephones are in use. Based on detecting when a first endpoint is in use and, therefore, when the endpoint's user is present, the private branch exchange controls one or more characteristics of the loudspeaker volume at a second endpoint. By accounting for other considerations such as the spatial closeness between the endpoints, which can be determined from office dimensions stored in a database, the private branch exchange of the illustrative embodiment is able to determine the degree of sound that is coupling over from one endpoint location to another. On a larger scale, the exchange is able to control the loudspeaker volumes of all of the endpoints in the workplace area. In doing so, the exchange manages the overall acoustic noise present.
