Abstract:
An interfacing device for connecting a telephone system to a call handling center which is in turn connected to at least one public safety answering point (PSAP) for providing information, the telephone system servicing a plurality of extension stations within a local facility, the interfacing device comprising:a. PBX interface means for connecting to said telephone system and receiving an emergency phone call from a specified one of said plurality of extension stations which initiated the emergency phone call;b. a display unit for displaying information about said specified one of said plurality of extension stations which initiated the emergency phone call;c. memory means for storing information on said plurality of extension stations within the local facility;d. 1.sup.st loop interface means having a 1.sup.st loop connection for connecting to said call handling center;e. 2.sup.nd loop interface means having a 2.sup.nd loop connection for also connecting to said call handling center;f. a central processing unit (CPU) connected to said PBX interface means, said display unit, said memory means, said 1.sup.st loop interface means and said 2.sup.nd loop interface means, and performing sequential logical operations;g. said CPU connecting the audio of the emergency phone call to said 1.sup.st loop interface means which in turn transmits the audio through said call handling center to said at least one PSAP through said 1.sup.st loop connection; andh. said CPU displayed the origin of said specified one of said plurality of extension stations which initiated the emergency phone call on said display unit while searching said memory means for information about said specified one of said plurality of extension stations, said CPU sends the extended station information through said call handling center to said at least one PSAP over a modem which is in turn connected to said 2.sup.nd loop interface means while maintaining contact between said specified one of said plurality of extension stations which initiated the emergency phone call and said at least one PSAP;i. whereby when the emergency phone call is initiated from said specified one of said plurality of extension stations within said telephone system in the local facility, the interfacing device can transmit extended station information of the extension station through said call handling center to said at least one PSAP, and also alert on-site personnel or security staff in the local facility that an emergency phone call has been initiated by one of the extension stations within the facility at the inception of the call.
