    摘要： A main terminal and a method of operating the same. In this method of operating the main terminal, the main terminal is connected to a telephone network so as to communicate with the telephone network, and selectively connects an external terminal to the telephone network. To perform the method, first, if it is requested that the telephone network be disconnected from the external terminal and instead be connected to the main terminal, an internal current to flow into the main terminal is obtained from a loop voltage generated when the external terminal is in connection with the telephone network. Next, the internal current is applied to the main terminal. Thereafter, the telephone network is disconnected from the external terminal and instead connected to the main terminal. While the internal current is flowing in the main terminal, the main terminal maintains the loop voltage generated when the external terminal is in connection with the telephone network. Accordingly, the telephone network can be disconnected from an external terminal and instead be connected to the main terminal without generating an interrupt. Thus, an exchanger included in the telephone network can be prevented from malfunctioning due to the generation of the interrupt.

    摘要： An audible signal associated with an event is provided as part of the audio path of a telephone. In particular, a telephone according to one embodiment of the invention includes a microphone adapted to receive audible signals from a user and to convert the audible signals to electrical signals for transmission to a distant party, and a speaker adapted to receive electrical signals associated with input from the distant party and to convert the electrical signals to audible signals. According to the invention the telephone also includes a processor adapted to produce electrical signals associated with an external event, and to integrate these electrical signals with the received electrical signals. In an alternative embodiment according to the invention, a method of alerting a party to a telephone conversation of an external event includes the step of providing an indication of the external event to the party from a speaker of the telephone during the telephone conversation. The external event can be a time of day, for example, and the indication can be a distinctive chime or an announcement of the time.

    摘要翻译： 主要终端及其操作方法。 在这种操作主终端的方法中，主终端连接到电话网络，以便与电话网络通信，并且选择性地将外部终端连接到电话网络。 为了执行该方法，首先，如果要求电话网络与外部终端断开，而是连接到主终端，则从外部终端产生的环路电压获得流入主终端的内部电流 与电话网络有关。 接下来，将内部电流施加到主终端。 此后，电话网络与外部终端断开连接，而是连接到主终端。 内部电流在主端子流动时，主端子保持外部端子与电话网络相连时产生的环路电压。 因此，电话网络可以与外部终端断开，而是连接到主终端而不产生中断。 因此，可以防止电话网络中包括的交换机由于产生中断而发生故障。
