Road vehicles - Interchange of digital information on electrical connections between towing and towed vehicles - Part 1: Physical and data-link layers
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.
