The physical layer synchronizes a small packet of tones to the zero-crossing of the power line’s voltage.
The bytes from the low-layer packets are reformed into bytes for the higher layers. Your basket is empty. Related standards use the physical layer e. Depending on the signal to noise ratios, the bits can be recovered from the difference between the power of the mark and space tones, the power of the mark tones only, 63134-6 the space tones only.

It is actually a series of standards describing the researched physical environment of power lines, a well-adapted physical layer, a workable low-power media access layer, and a management interface. Verteilungsautomatisierung mit Hilfe von Traegersystemen auf Verteilungsleitungen. The data from zero crossings should be collected into 8-bit bytes.
This is followed by 38 bytes of data, and 3 byte-times of silence. Accept and continue Learn more about the cookies we use and how to change your settings. The most significant bits are sent first, unlike a conventional serial port. In multiphase power lines, a separate signal might be sent on each phase to speed up the transmission.
