  • Communication system conferencing arrangement
    Patent number: 4150259
    Abstract: A communication conferencing arrangement is disclosed which relies upon the use of a plus/minus (+/-) nonlocking button followed by the operation of a button associated with any other line appearing at the station. If the operated line button is associated with a currently active line that line will be removed from the conference. If, however, the operated button is associated with a nonactive line (held or idle) then that line will be added, in conference fashion, with the communication leads of the enabling station. Provision is made to allow any number of added connections up to a preset maximum number at any station.

  • Communication system call transfer arrangement
    Patent number: 4125748
    Abstract: A communication system call transfer arrangement is disclosed which relies on the establishment of two system access buttons on every telephone served by the system. The system access buttons are operational to originate a call to any station in the system over any idle link. A call on either access line can be added to any other currently active line on the telephone set. The system access buttons at all the stations operate such that an incoming intercom call will terminate on eitherbutton, and calls can be originated from the station by using either button. For call transfer purposes the system access lines are arranged such that when the station passes a call via the access line to another station and then goes on-hook, the system access lines become idle and are available for use by the station even while the transferred call is in progress.
