Mini Automatic Telephone Exchange System (MINI ATE)

It is intended for providing of reliable and qualitative communications with possibility to organize  the internal  communication,   increasing efficiency of use of  the existing  local  phone lines, thereby decreasing expenses of it contents.

Automatic  telephone  exchange  (ATE)   satisfies  to  the international quality standards, providing uninterrupted communication at any load. It is simple in installation and is convenient in use.

The  given  advantages in a combination of easy  usage and obtainable price  do automatic  telephone  exchange   by  necessary  attribute  for business life of any firm. 

 

 

 MINI ATE

The main functions of the MINI ATE are: 

  • provision of local communication
  • distribution of incoming calls
  • various categories of access
  • organization of communication both with the centre battery (CB) and with a local battery (LB)
  • convenient remote dialectic mode of provision of commutation by the operator
  • auto attendant
  • inhibit  of intercity calling
  • conference communication
  • divert call
  • selector communication
  • call’s tariffication
  • possibility of connection with a urban telephone network through Е1
  • possibility of a group IP-telephony
  • archiving of conversations on selective channels
  • crypto-protection of communication channels.
  • direct exchange facilities

JAMMER OF THE CELLULAR PHONES SIGNAL OF GSM 900/1800 STANDARD

“JAM”

  

 

Jammer  “JAM” is intended for blocking (suppression) of the signals in 890....960 MHz and 1710...1880 MHz frequency ranges. At device switching on all cell phones which are in this range beginning operates in  searching mode.

It is recommended to apply:

  • in conference halls;
  • in theatres, libraries, cinemas, churches, temples, in hospitals;
  • on the territory of special objects;
  • at schools and institutes of higher education;
  • for security services (antiterrorism, blocking of listening in, "bugs" in the given range). 

The system has 2 independent radiofrequency sections with two direct antennas of both GSM ranges.

The following modifications   are suggested:

JAM- Out  - operating out-of-doors. In this case the level of output power is not adjustable.

JAM- In  - operating in-doors. In this modification the level of output signal on each channel is stipulated.

JAM  P  - low-power pocket.

Delivery set: 

Unit of cell phones signal supression  1 pc  
Antennas for two GSM range  2 pcs  
Fastening set and cables  2 pcs  
Passport, technical specification and user’s manual  

SPECIFICATIONS:


Maximum output power in each range: 
JAM Out-4  4W
JAM Out-10  10W
JAM In-100  Up to 100 mW

DIGITAL CONFERENCE - SYSTEM WITH SYNCHRONOUS

MULTILINGUAL TRANSLATION ( DCST)

 DCST is the hardware-software complex intended for carrying out of meetings and conferences up to 30 (60) participants.

Digital transmission of audio signals considerably simplifies maintenance of system. Provision of sound-on of halls and the organization of simultaneous interpretation in one or several languages (up to 6).

Simultaneous usage of two such systems enables increases of participants’ number up to 60 (120).

 

 DCST multipart assemblies are:

MD6-30 - central board (control unit by system) 1 pc
D6-30 - individual board of participants up to 30 pcs
TD-2 - boards of participants 1...6 pcs
DM6-30 - presiding board 1 pc
Set of connecting cables 1 set
RTS-1- radio transmitters up to 6 pcs
RTS-1 is necessary at combining of wire system with wireless. In that case the number of participants considerably increases and they have opportunity to move freely

DUAL AXIS LOW COST INCLINOMETER "MARKEL 2-01"

Inclinometer “МаrkEl 2-01” intended for high-precision measuring of angle of inclination in two axis.
It operates both autonomous and as a part of automatic control systems.

Inclinometers with an electric output signal, in proportion to an angle of inclination, are comparative new equipments produced for wide industrial application.

Its high accuracy, small sizes, absence of the mobile mechanical parts and simplicity of strengthening on object do expedient use its not only as sensor of roll but also to change by them angular sensors, and not only on stationary, but also on mobile objects.

 Fields s of application: 

  • Long-time definition of position’s changes of various high-rise buildings, dams, use in systems of platforms’ horizontalizing, definition of deflections and deformation values of different supports and blocks;
  • Control of slope angles of mobile roads and railways at its building, repair and maintenance; 
  • Definition of cars’ roll, road graders and asphalt pavers, cranes, excavating and agricultural machines;
  • Use in robots, machines and printing presses for control of the mechanism position, cutting element or printing presses rolling.
  • Use in the alarm and acoustic control systems.

 

Features:

Has a linear dependence of output signal from an angle slope in one - so-called working plane and practically does not change the values in other (non-working) plane, thus its signal weakly dependent on temperature change.
For definition of a plane position in space is used two located under 90 ° angle to each other inclinometers.

 

SPECIFICATION 

Range of a measured slope  ±5°
Threshold of sensitivity  0, 001°
