摘要
ISDN服务器是RBC系统的重要组成部分,负责管理从物理层到传输层的链路连接建立和释放,以及可靠的、透明的数据传输,并且完成与GSM-R无线网络、RBC通信机以及维护终端之间设备数据交互。提出了一种基于CTCS-3级列车运行控制系统的ISDN服务器实现方案,描述了系统软硬件设计、通信时序等关键技术的原理和实现。
ISDN Server is one of the crucial devices of RBC in train control system.The key function of ISDN Server is in charge of the establishment and release of connections from physical layer to transport layer,and ensure reliable and transparent data transfer,and complete data interchange with GSM-R wireless network,RBC communicator and maintenance terminal.A framework of ISDN Server based on CTCS-3train control system is presented and the principles and implementation of its key technologies,such as hardware and software design and time sequences of communication are described.
