What is ISO 21111‑2 about?
ISO 21111‑2 is part two of the multi-series standard that specifies the following items to complement ISO/IEC /IEEE 8802-3:
- Interface between reconciliation sublayer and physical entity including reduced gigabit media independent interface (rgmii)
- Common physical entity wake-up and synchronised link sleep functionalities independent from physical media and transmission bit rate
Note-
The optical and electrical component requirements and test methods for optical and electrical transmission of in-vehicle Ethernet is not in the scope of ISO 21111‑2.
Who is ISO 21111‑2 for?
ISO 21111‑2 on common physical entity requirements is useful for:
- Vehicle manufacturers
- In-vehicle ethernet providers
- Telecom network providers
- Vehicle testing facilities
Why should you use ISO 21111‑2?
As the use of the internet has increased devices are becoming smarter. Cars too are now connected to the internet with in-vehicle ethernet. The ISO 21111 series includes in-vehicle Ethernet requirements and test plans that are disseminated in other International Standards and complements them with additional test methods and requirements.
ISO 21111‑2 specifies the interface between reconciliation sublayer and physical entity including
reduced gigabit media independent interface (RGMII), and the common physical entity wake-up and synchronised link sleep functionalities, independent from physical media and bit rate.
ISO 21111‑2 provides supplemental requirements to a physical layer capable of transmitting 1-Gbit/s over plastic optical fibre compliant with ISO/IEC/IEEE 8802-3, with specific application to communications inside road vehicles, and a test plan for physical entity conformance testing.
ISO 21111‑2 gives service primitives, events, algorithms and state machines used to define the transition between the power states of a physical entity.
ISO 21111‑2 also specifies timing requirements to complete the defined algorithms
