A Eurobalise telegram contains one header and an identified and coherent set of Packets.欧洲应答器消息是指由一个应答器组发送的信息（即消息由一个或几个报文组成，这些报文根据应答器组中的应答器编号来分类（1号应答器的报文排在首位），每个报文都通过一个欧洲应答器进行传输。欧洲应答器报文包含一个报文头、标识号和一组连贯的信息包。Figure 1: Composition of a balise group message图1：应答器组消息的组成 A Euroradio message contains one header and an identified and coherent set of variables (if needed) and Packets.欧洲无线消息包含一个报文头、标识号、一组连贯的变量（如果需要）和信息包。 A Euroloop message contains one header and an identified and coherent set of Packets.欧洲环线消息包含一个报文头、标识号和一组连贯的信息包。8.4 Rules规则8.4.1 Common Rules一般规则 A message (Euroradio/Euroloop) or telegram (Eurobalise) shall be composed of1. One Header,2. When needed, a predefined set of variables (only for Radio),3. When needed, a predefined set of Packets (only for Radio),4. Optional Packets as needed by application.一个消息（欧洲无线/欧洲环线）或报文（欧洲应答器）应当由以下部分组成：1. 一个报文头；2. 在需要时，有一组预先定义的变量（仅适用于无线）；3. 在需要时，有一组预先确定的信息包（仅适用于无线）；4. 根据应用需求的信息包（可选）。 The transmission order shall respect the order of data elements listed in the message format (from top to bottom).传送次序应按照消息格式中数据元素的排列顺序（从上到下）。 The behaviour of the receiver shall not depend on the sequence of the Packets given by the message.接收器的动作与消息中信息包的顺序无关。.1 Exception for Infill information: The locations given in the packets following packet 136 (Infill Location Reference) shall be referred to the balise group indicated in such packet.注入信息除外：信息包136（注入参考位置）之后的信息包给出的位置应以此信息包指定的应答器组为参考。.2 Note: orientations are in any case always referred to the directionality of balise group (balise transmission), directionality of loop (Euroloop transmission) or directionality of LRBG (radio transmission).注：无论如何，方向总是以应答器组（应答器传输）的方向、环线（欧洲环线传输）的方向或LRBG（无线传输）的方向为参考。 It shall be forbidden to send more instances of the same packets type for the same direction in the same message.应禁止在同一消息中发送多个用于同一方向、信息包类型相同的信息包。.1 Exception 1: A message can contain several packets 44 (Data used by applications outside the ERTMS/ETCS system).例外1：一个消息可以包含多个信息包44（非ERTMS/ETCS系统使用的数据）。.2 Exception 2: A message can contain several packets 65 (Temporary Speed Restriction). The identities of the corresponding temporary speed restrictions (variable NID_TSR) transmitted in the same message shall be different.例外2：一个消息可以包含多个信息包65（临时限速）。但是在同一个消息中传送的与临时限速对应的标识号（变量 NID_TSR）应不同。.3 Exception 3: A message can contain several packets 66 (TSR Revocation). The identities of the corresponding temporary speed restrictions (variable NID_TSR) transmitted in the same message shall be different.例外3：一个消息可以包含多个信息包66（取消临时限速）。但是在同一个消息中传送的与临时限速对应的标识号（变量 NID_TSR）应不同。.4 Exception 4: A message transmitted by a balise group can contain one packet 136 per balise telegram per direction. Each packet 136 indicates which part of that telegram is to be considered part of the infill information. Multiple packets 136 in balises of a balise group shall have identical content per direction.例外4：一个由应答器组传输的消息可以允许每个应答器报文在每个方向都包含一个信息包136。每个信息包136说明了报文的哪个部分是注入信息。应答器组中的每个应答器包含的信息包136在每个方向上应具有相同的内容。.5 Exception 5: Intentionnally deleted例外5：有意删除。.6 Exception 6: A message transmitted by a balise group can contain several packets 254 (default balise or loop information).例外6：一个由应答器组传输的信息可以包含多个信息包254（应答器或环线默认信息）。8.4.2 Rules for Eurobalise telegrams欧洲应答器报文规则 The format of the telegram to be transmitted by each balise is as follows: General Format of Balise TelegramField No.VARIABLELength ( bits)Remarks1Q_UPDOWN1Defines the direction of the information: Down-link telegram (train to track) (0) Up-link telegram (track to train) (1)2M_VERSION7Version of the ERTMS/ETCS language.3Q_MEDIA1Defines the type of media: Balise (0)4 N_PIG3Position in the group.
