PINX是一种专用网络,用于在企业内部提供综合通信服务。PINX中的各个节点需要进行时钟同步,以确保通信的准确性和可靠性。ISO/IEC 15507:1997规定了PINX中时钟同步的要求和方法,以确保PINX中各个节点的时钟同步。
该标准规定了PINX中时钟同步的两种方法:基于时间戳的方法和基于时钟频率的方法。基于时间戳的方法是通过在PINX中传递时间戳来实现时钟同步的。基于时钟频率的方法是通过在PINX中传递时钟频率来实现时钟同步的。这两种方法都需要在PINX中定义时钟同步协议,以确保各个节点之间的时钟同步。
该标准还规定了PINX中时钟同步的要求。PINX中各个节点的时钟同步误差应该小于1毫秒。此外,该标准还规定了PINX中时钟同步的测试方法和测试要求,以确保PINX中各个节点的时钟同步。
总之,ISO/IEC 15507:1997是一项关于PINX中时钟同步的标准,规定了PINX中时钟同步的要求和方法,以确保PINX中各个节点的时钟同步。该标准对于企业内部提供综合通信服务的PINX网络具有重要意义。
