  • Assuring physical security of a subscriber line device
    Patent number: 7281131
    Abstract: A security system and method for a client device connected to a network by a broadband connection. The security system insures that the client machine has not been moved from its authorized location. A check is made to insure that the machine is located at its assigned location.

  • Auto-detection of ISDN BRI services
    Patent number: 6990125
    Abstract: A method and apparatus for auto-detection of ISDN BRI services available for use by terminal equipment is disclosed. This auto-detection provides a variety of simulated call activity stimuli to the ISDN switch peered with the terminal equipment, thus exercising secondary ISDN features such as call conferencing, call forward, call transfer, and X.25/D channel data transfer capability in a manner that can be detected by the terminal equipment. For instance, the call conferencing feature can be detected by having the terminal equipment place a call to it's own directory number using one B-channel, answering the call on the other B-channel, and then attempting to add a third party to this call. By evaluating the messages returned from the switch during the attempted third party addition, the auto-detection process can determine whether the call conferencing feature is available.
