Abstract: An intrusion sensing device includes an intrusion detection sensor enclosed within a housing and operable to detect an intrusion into a container. A mounting detection mechanism contacts the surface of the container when the housing is mounted thereto and is operable to detect when the housing is not in contact with the surface of the container. An access detection mechanism is operably connected to an access panel of the housing and operable to detect removal of the access panel from the housing. A control module is operable in a setup mode and an active mode. The control module is adapted to receive an alarm message from the intrusion detection sensor and operable to initiate an alarm event during the setup mode which varies from an alarm event initiated during the active mode. A wireless transmitter is operable to transmit an alarm indication signal to a remote monitoring system.

Abstract: A method and architecture for transitioning the embedded base of Digital Loop Carrier access systems from the current narrowband circuit-switched paradigm—i.e., Synchronous Transfer Mode transport and Time division Multiplexed—to an Asynchronous Transfer Mode transport and ATM network interface paradigm. The invention operates to terminate the control data links from legacy DLC equipment, and to provide a protocol conversion function that enables these links to interface with the associated control and call processing structures of a serving packet switch. An additional function of the invention is the interfacing for bearer channels of the STM feeders from the legacy DLC and the provision of a Synchronous to Asynchronous Conversion function on such feeders.
