Standard E-9-1-1 Interface TriTech Software Systems Glossary TERM Definition TriTech TriTech Software Systems SA System Administrator Client Interface The software module described herein VMS VisiCAD Message Switch VisiCAD Command The CAD Users I Customer personnel who perform dispatcher and call -taking functions Client I Client 2. Introduction The VisiCAD E911 Interface will transfer data from the E911 system into VisiCAD Command in order to display and record incoming 911 data specific to the caller's address location and telephone number. The information being captured will be used for the features outlined in this document. This standard VisiCAD interface provides a one-way transfer and management of data from the E911 controller to VisiCAD. Once the call -taker answers the call, the ALI trunk will assemble a data stream of fixed length or delimited fields that contain the attendant number, the telephone number, the location information, etc., and send the data packet to the VisiCAD Interface via an RS-232 (serial) connection. Once the interface receives a valid data packet, the data will be processed, storing selected fields into the VisiCAD database, and notify VisiCAD Workstations of the event. The target VisiCAD workstation will process the event by automatically opening a new Emergency Call Taking screen with select E911 data populating predetermined display fields. Alternatively, VisiCAD can be configured to initially display a pop-up verification window with summary information regarding the incoming E911 data. This Verification pop up window will ask the user if they want to accept or decline the information that is being displayed. If the user accepts the information displayed, the E911 data will be imported into the Emergency Call Taking Screen as described above. If the user declines the information, the E911 data will be discarded and a blank Emergency Call Taking Screen will be displayed. TriTech Software Systems is responsible for providing and initially configuring the VisiCAD E911 Interface software, and selecting the method of connection. CLIENT is responsible for the E911 controller, any necessary cabling, or communications connections, and arrangement and funding of any work. The customer understands that changes made to the E911 controller and/or network, including the format of delivered data, may disrupt the operation and functionality of this interface. 3. Functionality 3.1 Use Case: Matching Attendant Stations to VisiCAD Workstation The Interface provides a configuration to enable the user to set up the links between each phone system attendant station and corresponding VisiCAD workstation. Upon receipt of an E911 call, the Interface will identify the corresponding VisiCAD workstation with the E911 System attendant station number provided by the ANI/ALI data spill. The E911 Interface will then process the data, and, if a valid match exists, the interface will direct processing to that workstation. Alternatively, all incoming E911 data can be directed to specified VisiCAD workstation(s), regardless of any attendant station identification provided in the E911 data. If no match for the attendant number is provided for the ANI/ALI data spill. A VisiCAD Activity Log entry will be made with a format of: [Date Time] + [Activity] + [Comment].
