Abstract
FIELD: low-frequency communication systems for ships, submarines, etc. SUBSTANCE: system has symmetrical guide line with voice-operated subscriber telephone sets, small-size transceivers, portable radio sets, and interface units between subscriber telephone sets and transceivers arranged along this line. Voice information is transmitted via physical two-wire circuit by means of electromagnetic waves. Signals picked off transceiver are transmitted over two-wire communication line in either side and arrive through interface unit at other transceivers; same signals go through transceivers, are amplified in interface units, and radiated in ship's compartments. Radiated signals are received by portable radio sets. Two-wire communication line is routed both inside and outside ship's main hull. EFFECT: improved reliability and survivability of emergency communication system.
