Abstract

Сигнал для использования в проводной сети, соединяющей электронные устройства, содержащий опорное напряжение для подачи питания на электронные устройства; сигнал импульсного напряжения, несущий кодированную информацию для передачи между электронными устройствами; и цифровой сигнал, наложенный на выбранные участки сигнала импульсного напряжения, при этом цифровой сигнал содержит несущий сигнал, модулированный информационным сигналом, для передачи между электронными устройствами. Сигнал используется в сетях систем пожарной сигнализации, например, для передачи мультимедийных или иных данных, таких как управляющие сигналы, обеспечивая при этом совместимость с существующими протоколами при помощи сигналов с импульсного напряжения.
