The «E-11C» automatic encryption equipment of phone and digital information


The “E-11C” automatic encryption equipment of phone and digital information

The unified “E-11С” equipment for cryptographic protection of voice and data is intended for voice encryption that is transmitted in simplex, half duplex, duplex modes at the rates 1200, 2400, 16000 bps and data encryption in the duplex mode at the rates 1200, 2400 bps.

The product provides:

  • One channel operation over simplex, half duplex, duplex channels at the rates 1200, 2400, 16000 bps;
  • Transmission(reception) of the information on digital liaison channels, of channels of tonal frequency, of channels of a satellite communication, of VHF and HF radio channels, of physical communication lines;
  • Eight cipher key input with correction check and their storage while the keys are active;
  • Transmission (reception) of the documentary information from computer;
  • Maintaining of clock synchronization when reduction of communication channel reliability up to 5·10-2;
  • Light indication of operational modes and condition of a hardware;
  • Teamwork with equipment "E-11Н".
