Information processing systems. Fibre Distributed Data Interface (FDDI) - Physical layer protocol (PHY-2)1 Scope This part of ISO IEC 9314 specifies the Physical Layer Protocol (PHY), the upper sublayer of the Physical Layer, for Fibre Distributed Data Interface (FDDI). FDDI provides a high bandwidth (100 Mbit s), general purpose interconnection among information processing systems, subsystems and peripheral equipment, using fibre optics or other transmission media. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit s

Who is ISO 17634 for

BS EN 60349-4 also does not apply to minor machines such as windscreen wiper motors
