It details internal state content to include relevant variables such as levels, modes, linking and movement authority information, track and position report parameters, national values, driver and train data, and message text. The document also describes sequencing rules for tests, including ordering relationships and handling mode/level transitions, followed by telegram and message description references.","| ERTMS/ETCS – Class 1 |\n| --- |\n| On-board Data Dictionary |\n| REF : Subset-076-5-3\u003Cbr>ISSUE : Version 2.3.0\u003Cbr>DATE : 14/04/2008 |\n\n\n| Company | Technical Approval | Management approval |\n| --- | --- | --- |\n| ALSTOM |  |  |\n| ANSALDO SIGNAL |  |  |\n| BOMBARDIER |  |  |\n| INVENSYS RAIL |  |  |\n| SIEMENS |  |  |\n\n\n| THALES |  |  |\n| --- | --- | --- |\n\nMODIFICATION HISTORY  \n\n| Issue Number Date | Section Number | Modification / Description | Author |\n| --- | --- | --- | --- |\n| Version 0.0.1\u003Cbr>23-Mar-2001 | All | Draft | ALSTOM |\n| Version 0.0.2\u003Cbr>05-May-2001 | All |  | ALSTOM |\n| Version 0.0.3\u003Cbr>15-Mar-2002 | All |  | ALSTOM |\n| Version 0.0.4\u003Cbr>24-May-2002 | 4.\u003Cbr>1.
