Before implementation of the ACCJIN, agencies in the county processed data separately and could only transfer information to each other through photocopy and fax machines. Independent systems existed for records management, computer- aided dispatch, crime analysis, and jail administration. The initial funding for the network resulted from a lawsuit concerning contested DUI forfeitures. The network consists of two message switching computers, a private packet switching setup, and common software applications including a central name index, a justice automated want system, and a remote book capability. The ACCJIN has revolutionized methods of information exchange in Contra Costa County. Successful development of the program has been attributed to good communications, well-defined criteria, and ample funding. 2 references
