Abstract
A device for identifying a specific station, among a plurality of geographically-dispersed stations represented by a common phone number and serviced by a common PBX, which has initiated an emergency '9-1-1' telephone call. The specific station having initiated the call is identified to the appropriate public safety answering point (PSAP) which is connected in an enhanced '9-1-1' emergency call network. Typically, the PSAP and PBX have different protocols. The device functions to convert the protocol of the PBX to the protocol of the emergency call network. Further, it assigns an arbitrary designation representing the specific station identified as having initiated the emergency call. Further, the invention transmits the arbitrary designation to the appropriate PSAP for responding to the call.
