标准摘要
[中文适用范围]: IEC 60839 的这一部分规定了报警传输系统中标准接口使用的传输层消息结构、格式和传输程序。这应该用于所有此类接口,其中一个供应商的设备旨在与其他供应商的设备互操作,并且底层系统架构不提供支持公共应用层的必要设施。该结构遵循 OSI 针对分层协议的建议,允许灵活选择和使用较低层传输介质和协议,同时保持对通用应用层协议的支持。本标准同样适用于入侵、火灾、访问控制和社会报警系统之间的警报和其他消息的传输,以及其他类似系统之间的信息传输。本标准所要求的认证密钥的物理管理不包括在内。 [外文原描述]: Specifies the transport layer message structure, formats and transmission procedures to be used at standard interfaces in alarm transmission systems. Should be used at all such interfaces where equipment from one supplier is intended to inter-work with equipment from other suppliers, and where the underlying system architecture does not provide the necessary facilities to support the common application layer.
