C4i - Integrated Secure Voice and Data Communication Systems

C4i is an experienced turnkey communications systems supplier, integrator and maintainer of communications, command and control systems for defence (airforce, army and navy) and civilian customers around the world.

C4i has in-house hardware and software design, development and manufacturing capability. Our base product is the Switchplus® digital voice and data switch which has been used in applications such as:

• Air traffic control
• Air-ground-air voice and data communications
• Ground-ground voice and data communications
• Inter-site radar and data routing
• Remote radio control
• Mobile and fixed military secure (red / black) voice, command and control communications
• Naval shipboard and shore-based voice and data communications
• Voice communications system simulation
• Secure voice conferencing systems

SWITCHPLUS DIGITAL VOICE AND DATA COMMUNICATION SYSTEM

The Switchplus communication system consists of two main elements, the fully fault tolerant yet affordable Switchplus digital voice and data switch and a touchscreen based Human Machine Interface (HMI) with a customisable Graphical User Interface (GUI). These elements are coupled to communication equipment such as radios, PABXs, intercoms, direct telephones, etc to form total communications systems. The switch provides the core technology for the C4i product range.

The C4i-developed switch adheres to an open systems architecture by using industry standard interfaces and protocols such as X.21, X.25, G.703, fast and gigabit Ethernet, ETSI, CAS, QSIG, ISDN, DPNSS and TETRA and supports VOIP and TDM over IP. This allows for distributed architecture that places the correct equipment in the correct location to achieve an efficient cost effective solution for any customer.

The Switchplus non-blocking 'mesh' architecture ensures that a call will always get through the system.

The implementation of radio communications specific commands such as individual PTT, carrier detect indication, main / standby changeover, retransmission, voting and remote control are core features of the product.

With its modular design, Switchplus can be configured for small to large (i.e. up to 1,000 operators, 2,000 party conferences and control of 200 plus radios) communications systems that provide a variety of communications features and a wide range of analogue and digital interfaces to choose from.

The ruggedised version of Switchplus is suitable for use in transportable defence applications and has been designed and tested to MIL-STD-810E and MIL-STD-167 for shock and vibration as well as to MIL-STD-461/462 for EMI/EMC.

SECURE CONFERENCE SYSTEM

Designed for defence applications, the Switchplus Secure Conference System (SSCS) overcomes the limitation of point to point encrypted calls by providing customers with the ability to conference validated users of point to point encryption devices into any combination of user defined conferences.

The system provides audio announcements as parties enter and leave conferences, verification of security levels and user defined conferencing. Additionally, operators within a secure enclave can be provided the ability to join conferences with geographically distributed end users providing maximum flexibility for secure conferences.

The SSCS will work with numerous cryptographic devices including CONDOR, KY-57, KY-100, OMNI™, Sectéra® Wireline and Wireless, STE-R and STU-III.

TACTICAL RADIO INTERFACES

Our ruggedised radio interface units are readily adaptable to tactical land environments and facilitate the control of tactical radios over an IP network connection.

REMOTE RADIO CONTROL AND MONITORING

C4i has a fully developed software library supporting the remote control and monitoring of multi-vendor radio equipment and accessories at manned or unmanned sites through our PC based System Management Facility (SMF) or alternatively integrated on the operator touchscreen of a corresponding Switchplus system.

C4i has experience with leading radio manufacturers’ equipment including Park Air, Rockwell Collins, Rohde & Schwarz and Sunair and is continually building the software library with other manufacturers protocols.
