<p>This document describes the data link layer (DLL) and physical layer (PHY) for the two CAN-based network interfaces specified in the 11992-series.</p>
<p>The DLL sub-clauses are composed of:</p>
<p>— DLL protocol entity requirements;</p>
<p>— DLL device interface requirements; and</p>
<p>— DLL network system requirements.</p>
<p>Normally, the physical signalling sub-layer is implemented in the CAN protocol controller. The physical medium attachment sub-layer is normally implemented in the CAN transceiver or the System Base Chip (SBC). Optionally, it can comprise also additional protection circuitry. The media-dependent sub-layer comprises the connectors and the cabling.</p>
<p>The physical signalling (PS) sub-clauses are composed of:</p>
<p>— PS entity requirements;</p>
<p>— PS device interface requirements; and</p>
<p>— PS network system requirements.</p>
<p>The physical medium attachment (PMA) sub-clauses are composed of:</p>
<p>— PMA protocol entity requirements; and</p>
<p>— PMA device interface requirements.</p>
<p>The physical medium dependent (PMD) sub-clauses are composed of:</p>
<p>— PMD entity requirements;</p>
<p>— PMD device interface requirements; and</p>
<p>— PMD network system requirements.</p>
