TA-11 VOICE TERMINAL

TA-11 voice termianl is designed to provide telephone communications within the subscriber networks of automatic switching systems, field communication systems, public automatic telephone networks, manual switching systems, and also without switching systems, negotiating by means of a radio station using it as a final device. It is intended for operation in stationary objects and on the base of wheeled chassis in harsh operating conditions.

Basic technical properties:

  • operation in local battery, central battery and PBX modes with pulse and tone dialing over a two-wire communication line; 
  • "Whisper" mode with increase of transmission level by 10 dB, and disconnection of the acoustic call; 
  • "Long line" mode with increased transmission and reception levels for working in the local battery mode at long distances; 
  • possibility of sending of the integrity test signal, the SOS signal via the Morse code (in automatic mode), of any message in the Morse code (in manual mode) in the local battery mode to the line.
