Purpose目的This document defines the RBC/CTC interface application layer in WG DPL. 本文档定义了武广客运专线RBC/CTC接口应用层。RBC/CTC interface refers to the following interfaces: RBC/CTC接口指以下接口：RBC central CTC RBC和CTC中心RBC CSM RBC和CSM

5、In the rest of the document, CTC refers to all of the above interfaces. 在以后的文档中，“CTC”指以上这些所有的接口。1.2.

The CTC and CSM are supplied by the CRSC. The central CTC system communicates with the RBC through the

7、 CTC-RBC Interface Server which connects with the VIA and the communication bases on Ethernet. The CTC-RBC Interface Server is dual configuration and connects with several VIAs.RBC系统（包括RBC本地终端）由庞巴迪提供，CTC和CSM系统由通号公司提供，CTC系统通过CTC-RBC接口服务器（属CTC系统设备）和RBC系统的VIA设备通信，设备之间基于以太网通信。CTC-RBC接口服务器为双套配置，可同时和多套VIA

8、相连。When the message is transmitted from CTC to RBC, CTC send the message to configured VIAs, it is VIA functionality to decide which RBC shall process this input message.CTC向RBC传送消息时，直接将消息发送给所有的VIA，由VIA来决定发给哪些RBC。Figure 1 IL/RBC/VIA/CTC System Architecture图0 IL/RBC/VIA/CTC 系统连接图1 RBC/CTC系统连接Figure 2

10、的顺序排列的（最低有效字节优先）。1.5. Message Structure信息格式According to reference (3NSS008253D0008), the message structure of RBC/CTC interface is defined as the table 1. 根据参考文件(3NSS008253D0008)文档规定，RBC/CTC接口信息格式如表1。Table 1 Message structure of RBC/CTC I/F表1 RBC /CTC接口信息格式Field 字段Size 长度(bytes字节)Description 描述SN 序号

11、4 The SN is a running number in the CTC to recognise VIA acknowledgement. When the VIA has responded with the same SN, the message has been received correctly in the VIA. SN为在CTC内部连续的数字，用于确认VIA消息的接收。当VIA回应的消息中为相同的SN时，则认为此消息已经被VIA正确地接收了。Message sequence number消息序列号ACK 应答4 When a messages has been rec
