This document describes the data link layer (DLL) and physical layer (PHY) for the two CAN-based network interfaces specified in the 11992-series.
The DLL sub-clauses are composed of:
-  DLL protocol entity requirements;
-  DLL device interface requirements; and
-  DLL network system requirements.
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.
The physical signalling (PS) sub-clauses are composed of:
-  PS entity requirements;
-  PS device interface requirements; and
-  PS network system requirements.
The physical medium attachment (PMA) sub-clauses are composed of:
-  PMA protocol entity requirements; and
-  PMA device interface requirements.
The physical medium dependent (PMD) sub-clauses are composed of:
-  PMD entity requirements;
-  PMD device interface requirements; and
-  PMD network system requirements.
