Tennessee Information Enforcement System
The CJIS Support Center (CSC) is responsible for providing criminal justice and law enforcement agencies within Tennessee access to the Tennessee Criminal History Repository and NCIC. This is communicated using the Tennessee Information Enforcement System (TIES) network. The TIES, located at TBI Headquarters in Nashville, is a statewide communications network created to facilitate the exchange of information regarding crimes, criminals and criminal activity. TIES provides a dedicated, high‑speed message switching function for all city, county, state and federal law enforcement and criminal justice agencies in Tennessee. The TIES maintains computer interfaces to several key information systems on the state and national level, including the following:
- Tennessee Crime Information Center (TCIC): operated by the TBI and required by Chapter 10 of Title 38 of the Tennessee Code Annotated. The operations of TCIC and all of its component systems are subject to and controlled by the federal and state constitutions, all applicable federal and state law, all rules, regulations and guidelines promulgated by NCIC, Nlets and TBI rules. TCIC provides access to Criminal History Record information (CHRI) residing in the criminal records unit of TBI, as well as access to the TN Sex Offender Registry, TN Boat Registration File, and TIES Help File assistance.
- National Crime Information Center (NCIC): a nationwide, computerized information system established as a service to criminal justice agencies - local, state, and federal. NCIC serves criminal justice agencies in the 50 states, the District of Columbia, Puerto Rico, and Canada. Through established state systems, the NCIC System has become available for use by all criminal justice agencies. The goal of NCIC is to help the criminal justice community perform its duties by providing and maintaining a computerized filing system of accurate and timely documented criminal justice information.
- International Justice and Public Safety Network (Nlets): comprised of representatives of law enforcement agencies from each of the fifty states, the District of Columbia, Puerto Rico, US Virgin Islands, many federal law enforcement agencies, and the National Insurance Crime Bureau (NICB). They also have a connection to the Canadian Police Information Centre (CPIC) files. Nlets purpose is to provide interstate communications to law enforcement, criminal justice and other agencies involved in enforcement of the laws.
- Office of Information Resources (OIR): the state mainframe system provides access to databases containing Tennessee Driver License and Vehicle Registration Files. OIR also maintains and coordinates the T1 communication lines and pix boxes used by agencies to connect to TBI for TIES and Automated Fingerprint Identification System (AFIS) access.
CSC personnel also conduct triennial audits, provide relative training and technical assistance for more than 350 law enforcement and criminal justice agencies currently comprising the TIES network. Currently, there are more than 8,000 terminals, mobile units, and hand-held devices in the state accessing the TIES network.
