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.

Frequently Asked Questions (FAQs)

Can I just use my current system?

  • Any radios or equipment you wish to use on the network must meet P25 standards, pass the Compliance Acceptance Program (CAP), and be approved by CTS engineers.

Is the network vulnerable to outages?

  • Most sites are equipped with a standby generator and 8 hour battery backup systems, redundant HVAC systems, entry control and alarm, and fire detection systems.

Can you enhance radio coverage?

  • To improve street level/in-building portable radio coverage, beyond the network’s current capability, may require the user to purchase additional equipment (e.g., infrastructure, repeaters, etc.) to enhance reception.

Are communications encrypted?

  • Radios can be programmed for encrypted communication. The user is responsible for ensuring their radios and equipment are compatible.

 
Who is eligible to be on the Network?

  • Municipalities & public safety providers:
  • Law Enforcement
  • Fire Departments
  • EMS
  • Public Works

CLMRN User Survey

Feedback is important and benefits the whole group. Here’s what we learned from a recent survey:

CTS_HR_Logo_WhtBG

  • 77% reported improved interoperability with other users.

Users on their experience working with CTS Engineers –

  • "They were very informative and provided detailed information about the transition throughout the change over."
  • "Extremely helpful and responsive. Especially when called upon during critical incident."

Interoperability Memorandum of Understanding (MOU)

CTS is Making Interoperability a Reality. The State does not charge a fee for municipalities and public safety providers to join the CLMRN. The MOU offers written assurances for a multi-year period that outlines the responsibilities and expectations set for public safety partners to join the network. Contact us if you’d like an MOU for your organization. Click to review a draft of the MOU.

 

Next Step: Contact Us

Joining the CLMRN requires more than just flipping a switch. It’s important to note that any radios or dispatch consoles that you want to access the network must be compatible with the CLMRN. The best way to determine if you are eligible to join the CLMRN is to reach out and set up a conference call with the CTS team.
