DEVICE FOR WIRE BROADCASTING CENTER CONTROL

摘要

The invention relates to communication technology and may be used for control of unattended wire broadcasting centres control using a telephone circuit. A device for control of a wire broadcasting centre due to introduction of a glow-discharge indicator and connection one of output terminals of a diode bridge to the telephone circuit through RC-circuit allows preventing breakdown of the device and visual control of ring signal passing, if external high voltages accidental occur on the telephone circuit. The proposed invention allows reducing labour intensity of assembly, setting-up and periodic testing.
