The Digitised Trunk Communications System (D-TCS) is a high bandwidth data network that links together various battlefield communications systems and technologies, to enhance the command and control of integrated operations. Compared to the TCS, which was used by the Singapore Armed Forces (SAF) in the early 1990s, the digitisation and high bandwidth of the D-TCS allows for real-time transmission of voice and data over vast distances. This connects fighting forces in the battlefield to the command headquarters, facilitating the exchange of critical information and establishment of a common operating picture. The D-TCS can be used in both conventional operations as well as training exercises.

Features of the D-TCS

• Richer Information Exchange 
  The D-TCS provides high bandwidth connectivity with each radio capable of transmitting up to 34Mbps. The high bandwidth allows for a wider scope of communications such as videoconferencing, the transmission of high-resolution videos and photos, as well as real-time data and file sharing. This capability enables accurate and timely information exchange to establish a common operating picture, facilitating increased situational awareness and decision making on the battlefield.

• Superior Networking Capabilities            
  The older analogue version of the TCS was unable to connect various platforms into a single network. The digital technology of the D-TCS allows the integration of various communications technologies and systems used in the battlefield, into a single network. This facilitates information exchange between various SAF platforms such as Terrex Infantry Carrier Vehicles, Main Battle Tanks, High Mobility Artillery Rocket Systems, Apache Attack Helicopters, Unmanned Aerial Vehicles, and even individual soldiers equipped with Advanced Combat Man Systems. The communications systems on the various platforms are also able to transmit key battlefield information to the Division and Brigade Headquarters. This enables commanders to monitor all their forces in the battlefield, for tactical coordination and decision making.   

• Highly Secure         
  The D-TCS network is highly secure, with security measures such as customised encryption and firewalls. Information assurance technologies can also be incorporated and deployed to secure the D-TCS against the latest security threats.

• Highly Mobile, Quickly Deployable and User-Friendly            
  The D-TCS is highly mobile and quickly deployable. Setting up a D-TCS system from its basic components takes less than 30 minutes. D-TCS vehicles are also able to operate and travel across rough terrain. The improved technology and commercial networking equipment that have been incorporated into the D-TCS also makes it more intuitive and user-friendly.
