  "text": "The complete specification of these interfaces consists of two parts:\nspecification of the protocols for the transport of information from/to ERTMS functions and for ensuring safety in the communication.\nspecification of the interfaces between pieces of equipment. The interfaces between the equipment are described in:\nSection 4.2.6 (On-Board Interfaces Internal to Control-Command) for on-board\nSection 4.2.7 (Trackside Interfaces Internal to Control-Command) for track-side\nThis Basic Parameter describes the air gap between track-side and onboard Control-Command Assemblies. It includes:\nthe physical, electrical and electromagnetic values to be respected to allow a safe functioning\nthe communication protocol to be used\nthe availability of the communication channel\nThe following specifications apply:\nRadio communications with the train: Class A radio communication interfaces shall operate in the R-GSM Band. See Annex A, index 35. The protocols shall comply with Annex A index 10, 18, 19, 39, 40.\nEurobalise and Euroloop communication with the train: Eurobalise communication interfaces shall comply with Annex A index 9, 43.
