Railway applications. Communication means between safety equipment and man-machine interfaces (MMI). | Status: Withdrawn, Superseded

1 Scope This Technical Report defines, in accordance with the ERTMS/ETCS requirements:

1. a) for each DMI function to be exchanged to and from the driver, including ETCS, STM:

• . performances needed;
• . degraded modes recovering;

1. b) DMI Safety targets;
2. c) communication system requirements:

• . al-time capability;
• . performances (bandwidth, etc.);
• . expansion capability;
• . RAMS;
• . applicable standards;
• . degraded modes;
• . degraded modes management;
• . interface with other systems;
• . LCC requirements.

Each item in the list above corresponds to one chapter of the present document. Figure 1 — Systems concerned by this document This Technical Report does not cover the following items:

• . Train functions;
• . STM “Separate DMI” as defined in document [1] regarding DMI equipment that is part of the STM itself;
• . GSMR EIRENE functions;
• . Ergonomics;
• . Use of the ETCS DMI as a terminal server for maintenance purpose.
