Connecticut Telecommunications System (CTS) Unit
The Connecticut Telecommunications System (CTS) is comprised of several subsystems that are integrated into a statewide communications network. The CTS Unit operates under the Division of Statewide Emergency Telecommunications (DSET) and provides land mobile radio as well as other interoperable communications for the Connecticut State Police. CTS manages over 65 sites across Connecticut to support equipment in the subsystems. Many sites include an antenna support tower and shelter, built to specifications that exceed industry standards, assure survivability, and maintain network operations during extreme conditions.
The CTS Mutual Aid (8CALL/8TAC) system was implemented as part of the 800 MHz radio installation to provide interoperability communications between Public Safety Agencies. This complies with the National Public Safety Planning Advisory Committee (NPSPAC) recommendations, FCC Rules & Regulations, and Regions 8 & 19 Regional Planning Update Committee (RPUC) plans. Interoperability allows agencies to communicate with others regardless of manufacturer, equipment model, or frequency of their native system. CTS provides various ways to allow communication between agencies. The 800 MHz NPSPAC 8CALL/8TAC system, legacy radio systems and dispatch console cross patching can create many flexible interoperability configurations.
Connecticut Land Mobile Radio Network (CLMRN) The CLMRN is a trunked P25 Phase 1 (FDMA) & 2 (TDMA) 700 and 800 MHz system that provides 98% mobile coverage statewide. The network radio sites are linked with both microwave and fiber optic cable. This provides public safety grade reliability with 24x7x365 monitoring by a dedicated team of experts at the Network Control Center. Recent updates to the land mobile radio network have increased capacity; making it possible for municipalities, State and Federal agencies, neighboring states, and public safety providers to benefit from the advantages of the CLMRN. The network is able to integrate trunked systems with conventional radios and dispatch consoles and has over 15,000 radios currently in use.

Network Control Center (NCC) Key Responsibilities
Monitoring (24 x 7 x 365)
- Facilities, power, HVAC, site access, transport, circuits, P25 trunked radio system, conventional radio system
Documentation
- Logging of site activity and ticketing of trouble incidents and scheduled maintenance/repairs
Notification
- Utilization of multiple systems to provide notification to technicians and customers of service affecting work (scheduled & non-scheduled)
Reporting
- Daily, weekly and monthly system reports and ad hoc reports provided to CTS to support system health and peak performance
Reminder for current CLMRN users - we appreciate your feedback! If there are areas in your jurisdiction with poor coverage (e.g., calls drop, no signal, distorted sound), contact the NCC and report the issue. You can call the NCC 24x7 at (860) 685-8008. Do your best to describe details such as: geographic location, radio type (mobile, portable), if portable – how worn, in-building or outside, type of antenna (quarter or half wave). These details help our engineers address the issue.
