Vehicle Intercom System (VIC)


Vehicle Intercom System (VIC) is a digital intercom system for mobile crews, which allows you to organize internal communication between crew members, communication between crew members and external subscribers via radio, communication between crew members and external or internal telephone network subscribers for a wide range of different armored vehicles from light to heavy vehicles and command centers.
VIC provides the possibility of organizing voice communication between subscribers of similar equipment, subscribers of radio of a vehicle, subscribers of telephone networks connected to a vehicle.
VIC is built according to a modular structure and provides a flexible approach to creating an intercom system. The possibility of choosing the type of configuration depending on the requirements of the Customer, provides adaptation to the necessary operating conditions, in which individual members of the crew are provided with the implementation of the functionality of various degrees.
VIC’s modular structure also provides a cost-effective upgrade path, allowing you to add or replace equipment (intercom or radio subscribers) gradually with a financial resource.

System components

Main unit VIC-MU

The central unit of VIC-MU is the core of the system. The VIC main unit has eleven Ethernet data transmission interfaces, which are used to organize a local network of the facility and provide internal communication between subscriber terminals, VIC-RG radio station units and one specialized voice frequency path for connecting the VIC-SAU unit. VIC-MU has the ability to directly connect radio stations with an Ethernet interface (for example, Harris 7800 or Aselsan VRC9661) for data transmission.

Central tank unit VIC-CTU

Central unit VIC-CТU – a variant of the central unit with six Ethernet data transfer interfaces, which are used to organize the local network of the facility and provide internal communication between subscriber terminals, VIC-RG radio station units and one specialized tone frequency path for connecting the VIC-SAU unit. Designed for installation in linear combat vehicles.

  Phone connection unit VIC-PCU

The VIC-PCU unit provides operation with two external telephone sets such as TA-57U, TA-01 and others, as well as the connection of network equipment using three Ethernet connectors.
VIC-PCU supports power supply using “Direct PoE” technology with a voltage from 12 V to 27 V and an Ethernet cable length of not more than 50 m.
VIC-PCU provides registration of subscriber lines using SIP protocol followed by a set of voice codecs: G.711u / a, G.729a, G.726-32, T.38, V.21.

  Operator unit VIC-OU

The subscriber terminal of the VIC-OU operator has a graphical LCD display, an extended keyboard, an interface for connecting a headset, an interface for connecting a radio and / or an external loudspeaker, and an Ethernet data transmission interface. VIC-OU provides control of the conversation volume, indication of operating modes on the integrated display, radio communication with radio via radio connection units, operation in the object’s internal network, connection of an external loudspeaker, editing, sending and receiving text messages, control and setting the terminal using the built-in keyboard .

  Subscriber unit VIC-SU

The simplified subscriber terminal VIC-SU has a selective switch for selecting the operator’s work from one of the 4 radio included in the intercom system or the Intercom mode, an interface for connecting a headset, an interface for connecting a radio and / or an external loudspeaker, a transmission interface Ethernet data, volume control, LED display modes. VIC-SU is designed to provide internal and external communication as part of mobile objects. VIC-SU is an active network device that is used when building a local area network of a mobile object.
VIC-SU supports by default the following voice codec set: G.711 (A Law, u-Law) and Speex.

  Radio gate unit VIC-RG

The VIC-RG unit is designed to provide internal and external communication as part of mobile objects. It has an Ethernet data interface for connecting to a local area network and a PM interface for connecting a radio and / or an external loudspeaker. VIC-RG provides the interface between radio networks and IP-telephony in local computer networks and provides the ability to transfer data to the radio network, connect a loudspeaker and / or radio via the PM interface and control the output of the radio for transmission using a tangent signal.
VIC-RG is an active network device that is used when building a local area network of a mobile object.

  Loudspeaker

The loudspeaker AN420 is designed for loud listening of a radio subscriber. The loudspeaker AN 420 provides connection to a radio, connection to an analog telephone, the ability to connect a handset, the ability to adjust the listening volume.

Subscriber access unit VIC-SAU

The VIC access set is intended for providing internal and external communication in the structure of mobile objects, which are equipped with 360 ° rotating tower and which are equipped with the device VKU (rotating contact device). The access control set consists of the following devices: subscriber access block and access block. The access block of the subscriber VIC-SAU is installed near the workplace equipped with a shamrock with a chest switch. It allows the user to switch the gadget switch by connecting the object’s internal communication network.

Central calculation module (CCM)

CCM is intended to provide information processing (cartographic information, data obtained from external devices) and the transfer of processed information to the display device. With the help of CCM the Vehicle Intercom System allows:
– to provide display of cartographic information on input and display devices;
– provide the display of information about your own location on the background of a digital map using a GPS receiver;
– provide the laying of a route of the vehicle movement on a digital map and its transfer to users;
– provide display, storage and measurement of the length of the track;
– to provide drawing, display and modification of tactical signs on a digital card;
– to ensure the drawing and display of marks on the digital map;
– ensure the exchange of formalized teams;
– provide information display on the input devices and display information about the readiness to complete the assignment for the purpose of the appropriate model of military equipment.

 

  Onboard network filter

The filter of the on-board network is designed to reduce the ripple and noise of the on-board network of mobile objects on the sound paths of VIC equipment.

Power supply unit

The power supply unit is designed to stabilize the voltage from 9 to 36 V DC to a voltage of 27 V, as well as to filter the noise of the network, which supplies power to terminals and units of VIC. The PSU can be placed on a horizontal or vertical surface. The maximum load current of the PSU is 5A. The power supply has two voltage outputs 27V, which allows you to connect two power lines of VIC.
