    • A test system exactly checks the integrity of data in an ATM system, and generates a test cell of a desired band. In the first aspect of the system in which data stored in an ATM cell are transmitted in an 8-bit parallel format in the ATM system, a test cell generating device connected to an input line outputs a test cell having 1 in all of the eight bits or having zero in all of the eight bits, and the test cell confirming device connected to an output line of the ATM switch detects the above described data. In the second aspect, the test cell generating device provided in an input trunk outputs a test cell of a desired band based on a ratio between two optional integers N and n (N.gtoreq.n), the state of a buffer of the ATM switch is monitored, and a load test is conducted to determine whether or not any cell has been destroyed.
    • 测试系统精确地检查ATM系统中数据的完整性,并生成所需频段的测试单元。 在ATM系统中以8比特并行格式发送存储在ATM信元中的数据的系统的第一方面中,连接到输入线的测试单元生成装置输出具有1个全部八个的测试单元 位或在所有八位中具有零,并且连接到ATM交换机的输出线的测试单元确认装置检测上述数据。 在第二方面,提供在输入中继线中的测试单元产生装置基于两个可选整数N和n(N> / = n)之间的比率输出所需频带的测试单元,ATM的缓冲器的状态 监控开关,并进行负载测试,以确定任何电池是否已被破坏。

    • An ATM transmission system transmits cell-formatted data in an asynchronous transfer mode, and aims at conducting an online path route test in the system. If one path route only is established in the system, then one or more valid cell detecting units for detecting, upon receipt of a cell enable signal indicating that a valid cell to pass through the path route has been sent, the arrival of a valid cell are provided at an optional point including an ATM switch in the path route so that the path route can be partially or entirely validity-checked. If plurality of valid path routes are established, the system provides, in addition to the valid cell detecting units, a virtual path identifier and virtual channel identifier comparing unit for comparing values of the VPI and VCI stored therein with values of a VPI and a VCI added to an arriving cell, and a path route validity check unit for partially or entirely validity-checking a path route in the ATM transmission system.
    • ATM传输系统以异步传输模式发送小区格式数据,目的是在系统中进行在线路径测试。 如果仅在系统中建立一个路径路径,则一个或多个有效的小区检测单元在接收到指示通过路径路由的有效小区的小区启用信号已被发送时,检测有效小区的到达 被提供在包括路由路由中的ATM交换机的可选点处,使得可以部分地或完全地进行有效性检查。 如果建立了多个有效的路径路由,则除了有效的小区检测单元之外,系统还提供虚拟路径标识符和虚拟信道标识符比较单元,用于比较其中存储的VPI和VCI的值与VPI和VCI的值 以及路由有效性检查单元,用于部分或全部有效性地检查ATM传输系统中的路径路径。
