information, such as fixed addresses for wireline calls or GPS coordinates from wireless devices, to a public safety answering point (PSAP) occurs on limited point to point circuits using modems, the organization said. The just- published standard provides a way to deliver information from the ALI to the PSAP using data packets over a multi- point IP network, ATIS said. It also updates the data to XML syntax. The ESMI protocol will provide a “delivery envelope” that will enable not only voice, but video, graphics and images to be part of next generation emergency networks, ATIS said. Examples of potential services that could be triggered with a 911 call would include transmission of a map of known hazmat at an industrial site. The call could activate public or private video cameras at an incident site, ATIS said. The ESMI standard was prepared by the ATIS Emergency Services Interoperability Forum. It was reviewed by the American National Standards Institute and was accepted by that body for trial use, ATIS said. The Forum said it would continue to work on another standard to define additional protocols for the transfer of data within emergency services networks using internet protocols such as HTTP, SMTP and FTP. That standard is expected to be published in Q1 2006, ATIS said.
