Abstract
Emergency service calls, such as 911 calls, are routed to specially trained operators at public service answering points (PSAPs). A PSAP switch, a special focus private branch exchange (PBX), is provided for interconnecting incoming PSAP calls to a PSAP position staffed by a PSAP operator. The PSAP position comprises a telephone facility for talking to the caller, and a PC for accessing and displaying data about the caller, i.e., the caller'"'"'s address, and any special characteristics such as a caller'"'"'s disability, etc. An ISDN, (Integrated Services Digital Network), line connects a tandem access switch used for routing PSAP calls with the PSAP switch. The ISDN facility is used for conveying information about the caller for display at the PC of the answering PSAP position. Advantageously, this arrangement provides an integrated system for communicating both the voice of the caller, and the data describing the caller to a PSAP operator.
