  • ETSI H1/H2/H3.


  • Setting of connection to one device or several Lawful Interception devices by channels;
  • The issue of random sequence of operating commands on DL-1 (data link - 1) with a possibility of manual definition of separate command parameters, as well as with a possibility of random manual modification of a command body;
  • Acceptance and decoding of messages arriving from Lawful Interception on DL-1 (data link - 1) and DL-2 (data link - 2) with a possibility of view of separate message fields;
  • Forming of a test protocol containing the list of commands and responses;
  • The phone-tapping of the channel interval content with display of the signal oscillogram and a possibility of the record on the disk;
  • Forming and execution of certification test automation scripts;
  • Check of the complex operability in a self-testing mode;
  • Certificate of conformity.


The complex consists of the processor-monitor module (PMM) on the base of laptop and interface module (IM) providing interaction with 1..8 primary digital streams (TS-30). Built-in power sources in PMM and IM provide an autonomy of complex operation during long time. The phone-tapping of sound information is carried out with the help of built-in speakers or headphones of the package contents.

Technical characteristics:

  • The number of primary digital streams: from 1 to 8;
  • Communication protocols with Lawful Interception: 70,174,268;
  • TCP interface: Ethernet 10/100/1000М;
  • Power: 220V;
  • The mass of the set in a hermetic shock-proof suitcase: not more than 12,5 kg.

"Vitok-E1-Imitator"  has the certificate of conformity №000016, issued on December 23, 2013.
