The FUNCTIONS that are essential for the safe control of the railway traffic, and that are essential for the operation, including those required under degraded modes.\n2.. The INTERFACES.\n3.. The level of PERFORMANCE required to meet the essential requirements.\nThe specification of these functions, interfaces and performance requirements are provided in Chapter 4 (Characterisation of the Subsystem) where supporting standards are referenced.",
