Emergency call station identification system
First Claim
1. Apparatus for identifying, to an appropriate public safety answering point (PSAP) connected in a "9-1-1" emergency call network having a designated protocol, a specific station, of a plurality of geographically-dispersed stations represented by a common phone number identifiable by the "9-1-1" emergency call network and serviced by a private branch exchange (PBX) having a different protocol, initiating a "9-1-1" emergency call, comprising:
- (a) means for assigning an arbitrary designation representing a specific station identified as having initiated a "9-1-1" emergency call, and for transmitting said arbitrary designation to the appropriate PSAP; and
(b) means, integral in a common module with said assigning means, for harmonizing, prior to entry of the emergency call into the "9-1-1" emergency call network, the PBX protocol with the protocol of the "9-1-1" emergency call network;
(c) wherein the PSAP identifies the specific station having initiated the "9-1-1" emergency call based upon said arbitrary designation; and
(d) wherein the PSAP identifies the specific station having initiated the "9-1-1" emergency call without the need of any companion equipment to said module.

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.
