"Vitok-SDH" - telephony interception and monitoring on the communication network supporting SDH architecture.


  • Retrieval of audio data from STM-1/STM-4/STM-16 (ITU-T G.707) channels in the passive mode;
  • Possibility to analyze the channel structure with automatic identification of containers hierarchy, localization of signaling SS-7 (ITU-T Q.703, Q.704, Q.763) and audio (ITU-T G.711);
  • Processing of multiservice (voice+data) optical networks of STM-1/STM-4/STM-16 SDH level — any level hierarchies.
  • Wide capabilities for scaling, building of distributed hierarchy configurations (up to 100 optical channels in one hierarchy node);
  • Transfer of commands to LI Control Panel via the hub: via X.25, Е1/G.703 or TCP/IP, Ethernet protocols pursuant to Order No. 70 of the Ministry of Communications;
  • Optional compression of sound during transfer between the system components for installation on weak communication lines.

Technical characteristics:

Retrieval devices:
  • 1U form factor, 360W: 1 duplex optical channel STM-1,4,16;
  • 2U form factor, 460W: 4 duplex optical channels STM-1,4;
  • 4U form factor, 400W: 2 duplex optical channels STM-16.
