摘要： A route bypassing a root node is constructed in a network in which a spanning tree is formed. A received frame is sent out on a designated port as well as on a root port by using a designated-port data send-out function, provided that a transmitting port for the received frame is learned on the root port. When a frame is received on a blocking port, a transmitting port for a frame whose destination matches the source address of the received frame is temporarily learned on the blocking port by using a blocking-port learning function, on the condition that the destination of the received frame is already learned on some other port. When a frame whose destination matches the temporarily learned address is received, the temporary learning is changed to normal learning by using a temporarily learned address-based data transfer function.

摘要： A method of connecting a line concentrator to other line concentrators in a switching system, wherein a switching unit accommodates the line concentrator is provided. The method includes the steps of analyzing a call received by the switching unit through the line concentrator, and connecting lines that are accommodated by the line concentrator and are connected to the other line concentrators without connecting through the switching unit when the call is detected to be made between the line concentrator and the other line concentrators. Thus, a call can be made to a specific dial number without connecting through the switching unit provided in the switching system. Additionally, a call can also be made by use of another switching unit when a communication path between the switching unit and the line concentrator is overcrowded.
摘要翻译：一种将线路集中器连接到交换系统中的其他线路集线器的方法，其中提供了容纳线路集线器的开关单元。该方法包括以下步骤：通过线路集线器分析由开关单元接收的呼叫，以及连接线路集线器的线路，并且当呼叫被检测到时被连接到另一个线路集线器而不通过交换单元连接在线路集线器和其他线路集线器之间。因此，可以在不通过设置在交换系统中的切换单元的情况下对特定拨号号码进行呼叫。此外，当切换单元和集线器之间的通信路径过度拥挤时，也可以通过使用另一个切换单元进行呼叫。
