Abstract
THE PURPOSE OF THE STACOM NETWORK IS TO PROVIDE EFFICIENT TELECOMMUNICATIONS CAPABLE OF TRANSPORTING INFORMATION BETWEEN CRIMINAL JUSTICE AGENCIES IN OHIO ON A STATEWIDE SCALE AND TO AND FROM SPECIFIC INTERSTATE CRIMINAL JUSTICE AGENCIES. CRIMINAL JUSTICE AGENCIES ARE DEFINED TO INCLUDE AGENCIES WHOSE PRIMARY FUNCTIONS ENCOMPASS LAW ENFORCEMENT, PROSECUTION, DEFENSE, ADJUDICATION, CORRECTIONS, AND PARDON AND PAROLE. THE NETWORK IS DESIGNED TO HANDLE COMMUNICATION REQUIREMENTS AMONG THESE AGENCIES PROJECTED THROUGH 1985. THE BASIC CONFIGURATION OF THE NETWORK IS AN ARRAY OF SYSTEM TERMINATIONS CONNECTED THROUGH REGIONAL SWITCHING CENTERS. EACH SYSTEM TERMINATION WILL BE ONE OF THREE TYPES: INDIVIDUAL TERMINALS, GROUPS OF TERMINALS IN CITIES, AND INTERFACES TO REGIONAL CRIMINAL JUSTICE SYSTEMS. SYSTEM TERMINATIONS WILL BE CONNECTED TO A REGIONAL SWITCHING CENTER THAT SERVES THE AREA IN WHICH TERMINATIONS ARE LOCATED. FUNCTIONAL REQUIREMENTS OF THE STACOM NETWORK ARE DETAILED IN RELATION TO MESSAGE CHARACTERISTICS (DIGITAL MESSAGE TYPES, MESSAGE CONTENT, AND MESSAGE LENGTH), NETWORK MESSAGE HANDLING (MESSAGE ROUTING, MESSAGE PRIORITIZATION, RESPONSE TIME GOALS, LINE PROTOCOL, MESSAGE CODING, ERROR DETECTION, AND NETWORK STATUS MESSAGES), SYSTEM TERMINATIONS, REGIONAL SWITCHING CENTERS (SWITCHERS WITHOUT DATA BASES AND SWITCHERS WITH DATA BASES), NETWORK AVAILABILITY, TRAFFIC VOLUMES, AND CONSTRAINTS AND BOUNDARIES (DATA HANDLING, DATA RATE, SECURITY AND PRIVACY CONSTRAINTS).
