| 释义 | X.25 X系列第25号标准 A CCITT recommendation relating to the interface between a packet switching network and a packetmade DTE (a computer). It describes the interface on three levels: Level 1 deals with the circuit interface between a DTE and a DCE; it is currently the same as that of CCITT V.24. Level 2 deals with the “frames”in which packets are sent. It defines the beginning and ending flags, an errordetection frame check sequence (FCS) and the method of sequencing frames. Level 3 deals with the “packetlevel”interface. It covers setting up and clearing virtual circuits, error conditions and interrupts, and packet sequencing. 国际电话电报咨询委员会发布的关于交换网络与信息包方式数据终端设备(计算机)之间 的接口的建议。该建议所述的接口分为三层:第一层涉及数据终端设备(DTE)与数据电路端 接设备(DCE)之间的接口,目前与CCITT V.24相同。第二层涉及发送信息包的“帧”,其中 定义了起始标记、结束标记、用于错误检测的帧检查序列(FCS)及帧定序的方法。第三层 涉及“包级”接口,其中包括虚拟电路的建立与清除,误差条件与错误中断,包定序等。 |
