    • The present invention realizes a digital switching equipment provided with an extra PCM highway without an unnecessary increase in the capacity of the time division switch. A time division switch is provided with first PCM highways connected to all card slots and a second highway connected to a predetermined card slots. Each of all the card slots have a function of outputting first address setting signal signifying an initial time slot position of the card slots capable of using the first PCM highways. Each of the predetermined card slots, to which the second PCM highway is connected, has a function of outputting a second address setting signal signifying an initial time slot position of the card slots capable of the second PCM highway can use.
    • 本发明实现了具有额外的PCM高速公路的数字交换设备,而不会不必要地增加时分开关的容量。 时分开关设置有连接到所有卡槽的第一PCM高速公路和连接到预定卡槽的第二公路。 所有卡槽中的每一个具有输出表示能够使用第一PCM高速公路的卡槽的初始时隙位置的第一地址设置信号的功能。 与第二PCM高速公路连接的每个预定卡槽具有输出表示第二PCM高速公路能够使用的卡槽的初始时隙位置的第二地址设置信号的功能。
