    • A telephone connection is established between a pushbutton telephone set and one of telephone lines through a pushbutton telephone set unit, a speech highway, and a telephone line unit. When one of line and extension keys of the pushbutton telephone set is pressed by the user during the telephone connection, a CPU in a control unit determines whether the telephone connection is being made based on the period of time that has elapsed after the pushbutton telephone set has captured the telephone line. If the telephone connection is being made as determined by the CPU, then the CPU controls a time switch circuit according to hold function data stored in a RAM to connect the telephone line unit to a hold tone generator through the speech highway, thus holding the telephone connection. Thereafter, the CPU captures a telephone line corresponding to the depressed one of the line and extension keys.
    • 通过按钮电话机单元,话音高速公路和电话线路单元,在按钮电话机和电话线路之间建立电话连接。 当在电话连接期间用户按下按钮电话机的线路和分机键之一时,控制单元中的CPU基于按钮电话机之后经过的时间段来确定是否正在进行电话连接 已经抓住了电话线。 如果由CPU确定电话连接,则CPU根据存储在RAM中的保持功能数据来控制时间切换电路,以通过语音高速公路将电话线单元连接到保持音发生器,从而保持电话 连接。 此后,CPU捕获与按下的线路和分机键相对应的电话线。
