    • In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes, HDLC data is transferred from a first terminal to the first communications node via a first transmission line, the HDLC data conforming to an HDLC format. It starts to assemble, in the first communications node, at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received. Then the above at least one cell of ATM data is transferred from the first communications node to the second communications node. Disassembly is started, in the second communications node, of the above at least one cell of ATM data to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell of ATM data among the above-mentioned at least one cell of ATM data is received by the second communications node. The fluctuation compensation time is based on a maximum fluctuation time of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line. Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line.
    • 在具有第一通信节点和第二通信节点的通信网络的ATM信元组装和拆卸方法中,HDLC数据经由第一传输线路从第一终端传送到第一通信节点,HDLC数据符合HDLC格式。 当接收到包含在HDLC数据中并且等于一个小区的数据时,它在第一通信节点中开始组合来自HDLC数据的至少一个小区。 然后将上述至少一个ATM数据单元从第一通信节点传送到第二通信节点。 在第二通信节点中,在ATM数据的上述至少一个小区中开始解码,从而在上述至少一个小区中的ATM数据的第一小区之后经过了波动补偿时间后生成原始HDLC数据 ATM数据由第二通信节点接收。 波动补偿时间基于将第一通信节点和第二通信节点彼此连接的路由的最大波动时间以及第一传输线路的比特率。 最后,原始HDLC数据经由第二传输线从第二通信节点传送到第二终端。
