摘要： A system and method for detecting cut-off of calls in a switching system records data corresponding to connection of a call in a first memory, records the call connection data in a second memory, and then at a later time and, for example, in response to a call release request compares the data in the two memories corresponding to the call. If the data does match, it is determined that the call has been cut-off. The first memory may be located in a switching unit and the second memory may be located in a processor which controls the switching unit. The switching unit may be a time switch or a space switch. Once a call cut-off is detected, the processor transmits information notifying an operator of the cut-off. The system and method represents an improvement over existing systems in terms of increased reliability and ease of repair and maintenance of system components.

摘要翻译： 用于检测交换系统中的呼叫截断的系统和方法将与第一存储器中的呼叫的连接相对应的数据记录在第二存储器中，然后在稍后的时间，例如在 响应于呼叫释放请求比较对应于该呼叫的两个存储器中的数据。 如果数据匹配，则确定该呼叫已被截断。 第一存储器可以位于切换单元中，并且第二存储器可以位于控制切换单元的处理器中。 开关单元可以是时间开关或空间开关。 一旦检测到呼叫截止，则处理器发送通知操作者截止的信息。 该系统和方法代表了在提高系统组件的可靠性和易于维护和维护方面对现有系统的改进。
