ABSTRACT:
A data request router for use with a public safety answering point (PSAP) system. The router receives a data request from the PSAP system and transmits the data request to a primary database and an alternate information sources. The router is capable of determining whether the primary database is able to provide the data requested by the PSAP system. If the router determines that the primary database is unable to provide the data requested, it receives a reply from the alternate information source and transmits the data contained in the reply from the alternate information source to the PSAP system. In one aspect, the router includes a switch designed to directly connect the PSAP system to the primary database when the router becomes inoperative either due to a failure or loss of power. In another aspect, the router transmits the data request received from the PSAP system to the primary database and determines that the primary database is unable to provide the data requested when a reply from the primary database does not contain the data requested. In another aspect of the invention, the router determines that the primary database is unable to provide the data requested by the PSAP system by analyzing the data request received from the PSAP system.
