The bytes from the low-layer packets are reformed into bytes for the higher layers.

This is followed by 38 bytes of data, and 3 byte-times of silence. Related standards uec the physical layer e. The higher link-layer strongly resembles HDLCexcept with a novel feature that allows selected stations to retransmit messages.

The physical layer synchronizes a small packet of tones to the zero-crossing of the power line’s voltage. We use cookies to make our website easier to use and to better understand your needs.

One tone is chosen for mark i. Each byte is collected into byte packets.

The standard’s low speed is caused by the limited number of bits per power line cycle. For example, it lets a central controller read a unit’s idc to noise ratios, and set the bit that enables a station to retransmit weak stations.

The silence and the preamble allow the receiver’s signal processing to measure the channel’s noise ratios. You may find similar items within these categories by selecting from the choices below:. Depending on the signal to noise 61334-66, the bits can be recovered from the difference between the power of the mark and space tones, the 61343-6 of the mark tones only, or the space tones only.

Automatisation de la distribution a l’aide de systemes de communication a courants porteurs. The tones are chosen by utilities, not specified in the standard. The frequencies are placed far enough apart that frequency-selective fading and narrow-band interference only blocks one of the frequencies, so the receiver can still recover all the data from the other frequency.

611334-6 high reliability comes from its reliable timing system i. In multiphase power lines, a separate signal might be sent on each phase to speed up the transmission.

The physical layer is adaptive. The data from zero crossings should be collected into 8-bit bytes. The standard permits each zero-crossing to convey 1, 2, 4 or 8 bits, with increased sensitivity to timing as the number of bits increases. The most significant bits are sent first, unlike a conventional serial port.
